What type of torch does the Forney 140 MIG use?

The Forney 140 MIG uses a Tweco style torch and uses Tweco #1 consumables for <200A machines and Tweco #2 consumables for >200A machines.

Can I weld stainless steel with the Forney Easy Weld 125 FC?

No, stainless steel requires gas to weld. The 125 FC (Flux-Core) does not use gas. We recommend Forney MIG machines for welding stainless steel.

What is the best MIG wire to use on stainless steel?

We recommend Forney ITEM# 42298, ER308L, .030″ x 2 lbs. Stainless Steel MIG Welding Wire.

Can I operate the Forney Easy Weld 125 FC on any surge protected outlet?

This machine should be fine to run on a surge protected outlet. You will want to make sure the rating for current on the surge protection outlet is at least 25 amps for this machine or it could damage the surge protector (depending on the type of surge protector).

What is the minimum wattage necessary to run the Forney Easy Weld 100 ST from a generator?

This welder requires a minimum 3500-watt generator to operate properly.

What is the amperage at duty cycle for the Forney Easy Weld 125 FC?

80 Amps at 20%.

Why is my Forney Easy Weld 125 FC not welding correctly?

Here are a couple of common issues:

  • Check the tension on the despooler. Is it set too tight or is the wire feed tension not set correctly?
  • Are you using .035” wire? We recommend .030″.
  • Is your stickout too long? Your stickout should be no more than ½”.
  • Make sure you are pulling the trigger on the MIG gun to begin welding.
  • Make sure the ground is not attached to painted or coated metal.

Why is my Forney Easy Weld 100 ST not welding correctly?

Here are a couple of common issues:

  • Electrode choice:  We recommend the Forney E6013 & E7014. The Forney brand performs very well even up to a 1/8” electrode.  Other brands of electrodes often require more amperage.  Some types of electrodes like E6010 and E7018 also require higher amperage and may not be the best choice for the Forney Easy Weld 100 ST.  An E6011 can also be used.  Some electrodes and brands will be limited to the 3/32” diameter because of their amperage requirements.
  • Use of extension cords:  If you need to use an extension cord, we recommend a 10 gauge cord, no longer than 50 ft. or a 12 gauge at 25 ft.  A small gauge extension cord like 14 or 16 gauge will choke the incoming power and reduce your power output which will create frustration.
  • The ground is attached to painted or coated metal.

Can I TIG weld aluminum with my MP machine?

No, you would need an AC TIG machine with HF (High Frequency) start for TIG welding aluminum.  However, you could MIG weld aluminum with a 190 MP machine if you purchase the optional spool gun.

Remember, when you weld aluminum, you will need 100% Argon gas.

Can I weld aluminum with my Easy Weld machine?

No, you cannot weld aluminum with an Easy Weld.

  • If you have the Forney Easy Weld 100 ST Stick machine, you need more amperage than the 100 ST puts out.
  • If you have a Forney Easy Weld 125 FC MIG, there is no aluminum flux-cored wire.

Is it possible to weld aluminum with the Forney 140 MIG?

Assuming you have the right gas, you can weld aluminum with the 140 MIG, but it’s not capable of using a spool gun.  We suggest you change the liner in the lead to a Teflon or plastic one instead of the steel liner that comes in the lead.  Aluminum wire is a lot softer and can get caught in the steel liner.

Can the 125 Forney Easy Weld weld 1/8″ steel using a 15 amp circuit?

The 125 FC (ITEM# 299) machine is capable of welding 1/8″ steel and the plug can be 15 amps but the breaker should be 20 amps. The power cord is a 15 amp cord.

What is the difference between a Dinse and Euro connection?

Euro Connector – the Euro connector is for a MIG welding gun.  The larger hole is where the wire goes, medium size hole is for the gas and the two small holes are what control the trigger.  The brass casing transfers the welding power.

Dinse Connector – is a type of connector for welding cables, ground clamps and electrode holders.  It’s a male/female type connection that transfers electrical power. It is usually electrically hot.

What style and size connector is used on the Forney Easy Weld 100 ST?

Both the electrode holder and ground clamp connections require a size 25 Dinse connector.  A Dinse style connectors pushes in and with a quarter turn, locks in place.

What types of metal can I weld on?

The below PDF lays out the different welding processes, metal uses and also has charts on general welding information and recommendations.

Helpful Welding Information

Is there a TIG torch available with a fingertip control?

Unfortunately, Forney Industries doesn’t offer a TIG torch with a fingertip control.

What are the limitations of the 140 MIG?

Excerpt from a Technical Bulletin:

The Forney 140 MIG as well as other high output 120V machines often produce end-user frustration due to the breaker popping and needing to be reset.  This is a common problem and is very noticeable if the customer is using a 15 Amp breaker, using .035” wire, or is pushing the wire feed limits of the machine while on tap setting 4. 

When designing a 120V machine, there is a balance between maximizing the output of the machine or never blowing a breaker, but having a poor output machine.  We chose to maximize the output of the machine as the machine settings can always be turned down.  The performance of the Forney 140 MIG machine has the highest rated duty cycle and output at 90A at 35% in its class. 

Try reducing the tap setting, reduce the wire feed speed, reduce the wire diameter, or get a less capable machine.  Also, verify the breaker output and have an electrician install the largest breaker that can safely be used per electrical codes.  The chart below will provide some guidance:

140 MIG reference.png

What is the required amperage of the outlet for the 140 MIG machine?

The required amperage for the 140 MIG machine is 20 amps.

What contact tips do I use for the 140 and 190 MIG welder?

You can use the following contact tips depending on the size of wire you’re using:

Is the Forney ITEM# 85363, argon/co2 regulator compatible with Hobart?

Yes, the Forney ITEM# 85363 regulator is compatible with Hobart welders.

How do I set up the TIG option without a foot pedal and switch control?

Our TIG torch has an on/off switch that connects to the amphenol connection. It is a 17FV so it has a flex head and valve. If you use a foot pedal you do not need a trigger torch.

I’m looking for a gift for someone with limited welding experience looking to get into metal art. What do you recommend?

We offer everything from entry level welding machines to light industrial machines, torches, plasma cutters, and filler metals. The following are some recommendations:

  • Welding Machine: We would recommend the 190MP which is a Multi-Process machine, capable of MIG welding, Stick welding, and TIG welding. This machine is ideal for a fairly advanced DIY artist. You can plug it in to 230V or standard household 120V with the included adapter. Depending on the type of project or artwork he is creating will dictate what welding process is best. In this case, he has three processes to choose from. This machine gives him a lot of capability to grow into. The spool gun and TIG torch are sold separately.
  • Plasma Cutter: We would recommend the 325P Plasma cutter which is good for cutting thinner material up to about 3/8″ of an inch. Artists often like to cut out intricate metal shapes – this is a good choice that provides a better quality cut than an oxy-acetylene torch. With this plasma cutter, you do need a compressor to supply the air flow. The compressor should have a filter in place to eliminate moisture and contaminants from entering the plasma cutter. This machine is very easy to use.
  • Filler Metals: Most artists are working with steel or stainless steel. For steel MIG, we would recommend ER70S-6 MIG wire with a 90/10 shielding gas. For steel stick electrodes, we would recommend either E6013 or E7014 electrodes in the 3/32 & 1/8″ diameters. This leaves a nice looking welding bead and they are easy to use. For stainless steel, a ER308L MIG wire or E308L stick electrode is appropriate for most applications.
  • Accessories: Don’t forget an auto darkening helmetwelding gloveschipping hammerwire brushsafety glassescutting and flap disc abrasives to make sure he has all the accessories he needs to get started.

How do you join 304 stainless steel?

Most people will use a 308L electrode or wire for joining 304 stainless steel (which is by far the most popular stainless base metal).  You can easily join stainless steel with MIG, Stick or TIG welding.  It comes down to speed, precision, and location for which process will work best for you.

  • If you are working inside and need a perfect weld, then use TIG with 100% argon and a ER308L rod.
  • If you need speed and a good looking weld, use MIG with a 98/2 shielding gas and a ER308L wire.
  • If you are doing outdoor work, then use Stick with an E308L electrode.

How do you join fine art aluminum?

We recommend TIG welding with AC, 100% argon gas, and 2% Lanthanated tungsten.  The most common filler metal is ER4043.  For welds that need higher strength or will be heat treated, the ER5356 is the best.  There are many types of AC TIG welders but we would recommend one of the newer inverter style machines because you can adjust the AC parameters and really dial in a beautiful weld.  The Forney 220 AC/DC is a good choice.

Artistic TIG welding on aluminum will take some time to learn even if you TIG weld steel or stainless steel on a regular basis.  Once you learn the TIG machine and the potential adjustments, the results can be spectacular.  We always recommend using a foot pedal if possible as this helps you better deal with crater cracks by slowing down the amperage at the end of the weld and helps control the heat.  Some common settings for aluminum is: balance at 60-70% EN, frequency of 60-90 Hz, 0.5 second pre-flow, and 4-8 seconds of post-flow.  Some welders also like to add pulsing while working with aluminum.

Preheat on thicker section or large material is often needed because of the high thermal conductivity of aluminum.

How do you join fine art brass/bronze/copper?

There are a number of ways to join various types of brass, bronze or copper materials.  The most popular method, especially with artistic work, is to “silver solder” (technically – silver brazing) the alloys together.  It’s generally recommended you use a brazing product with at least 15% silver as this will allow you to join almost any copper or brass alloy to another.  Some will use a silver brazing alloy with up to 56% silver content.  But with that much silver, the brazing rod will be very expensive.  Most people use an oxy-acetylene torch for brazing.

For a secondary choice, many artists use TIG welding, although this requires more skill than brazing.  A silicon bronze filler material is often used.  Some prefer to Stick weld which is a good choice for particularly thicker sections over 1/8″.  For Stick welding, a silicon bronze or aluminum bronze electrode is a popular choice.  If color match is critical, then finding the right filler material can be very difficult and time consuming.  For lighter color bronzes, use an aluminum bronze, and for more of a reddish bronze, use a silicon bronze filler metal.

Any time you are working with copper or brass products that are thick or large, preheat is often used since copper has such a high thermal conductivity.

What’s the best wire diameter for the 95FI?

The machine can use .035” but it doesn’t do well with that diameter.  We recommend no larger than .030”.

What is the correct wire diameter range on the 270 MIG, 210 MIG, 140 MIG, and 190 MIG?

Both .024″ and .023″ are correct but .024” is a little more common and what we use for MIG wire in our catalog.  It’s a rounding issue plus MIG wire has a .003” tolerance in diameter

Does Forney ITEM# 42300 2# Flux Core MIG Wire .030″ require the use of gas?

Gas isn¹t required for Forney ITEM# 42300, although you may use gas if you¹d like.

What do I do when my machine is sputtering?

The wire feed could be set too high for the specific voltage you are at.  Give us a call at (970) 472-7056 to speak with a Technical Service technician to discuss your settings and diameter.

The welder keeps tripping my breaker, what do I do?

Make sure everything else is turned off using that circuit, and we recommend a dedicated circuit for a welding machine.  A welding machine will use all the power you can give it.

Are the drive rolls interchangeable among Forney machines?

Yes, they all use the same but there are drive rolls for different diameters and some dedicated to flux core, some for aluminum.

How do I spray weld?

Spray transfer requires a high output welder (the 210 MIG or 270 MIG), the right shielding gas (90/10 Argon/CO2 mix), the right voltage setting for the proper wire size (the 210 MIG can spray transfer .030” on tap setting six, while the 270 MIG can spray transfer .030” and .035” wires but usually you have to be in the top two voltage tap settings).

While welding in the spray transfer mode, the weld will produce a humming sound with almost no spatter while the short arc transfer produces more of a crackling/buzzing sound and very fine spatter.

What are your suggestions to avoid porosity?

Check for:

  • Are there any leaks?
  • Using the right type of gas for material?
  • Dirty material
  • Dirty or rusty wire

What are some suggestions for solving wire feed issues?

Start at the despooler and work forward. Check the following:

  • Correct wire size
  • Cleanliness of wire
  • Despooler tension
  • Drive tension adjustment
  • Drive roll size
  • Guide tube alignment
  • Any burr on liner
  • Correct liner size
  • Cleanliness of liner
  • Tip size correct

If you’re still having issues, call our Technical Support line at (970) 472-7056 for further assistance.

What MIG wire diameter is recommended?

It depends on how thick the material is that needs to be welded, but in reality the .030” wire diameter is probably the most versatile.  With an .030” wire you have the ability to weld thin sheet up to thick plate (with multiple passes).  The .030” wire also gives the welding machine a larger wire feed speed range to optimize the arc characteristics.  Some people will argue the .035” wire is more versatile and this is true if you are using a 200A+ machine, but on a machine that’s less than 200A, go with .030”.

Can I weld aluminum with a 190 MIG machine?

Start at one end and work the other (gas = 100% Argon, drive rolls = U-groove), lighter tension on drive system, Teflon liner (special order), and a larger diameter tip.

Also use a larger diameter wire like .035″ or even .045″ so it’s stiffer and easier to push.  Remember that a spool gun works best.

Can I use a .045″ MIG wire on the 140 MIG machine?

No a .035″ wire is the maximum size the 140 MIG can handle; we recommend a .030″.

Which machines are appropriate to use with a 5/32″ stick electrode?

Are the MIG guns all interchangeable on the 140 MP, 190 MP, 140 MIG, 190 MIG, 210 MIG and 270 MIG?

Yes, except the 270 MIG uses Tweco #2 because the higher output would burn up a Tweco #1.  The 210 MIG is unique.

What style consumables does a Forney 270 MIG use?

Tweco #2

Which Forney machines have 8′ and 15′ power cord?

The 140 level machines have an 8′ and 190 level machines on up have a 15′.

Which flux and rod do you recommend using in combination to fill pin holes up to 1/4″ in stainless steel material?

Instead of using a brazing rod and your oxy/acetylene set up, a better solution would be the use of stainless steel MIG wire, TIG welding, or even a stainless steel arc rod.

Does Forney have a low temperature aluminum rod?

Yes, ITEM# 46111.  It can be used with either oxy-acetylene or propane torch and has a melting point of 732 degrees Fahrenheit.

How are multi-process (MP) machines typically set up?

It depends on what you intend to do, but for everyday versatility we suggest to run an .030” diameter solid ER70S-6 wire with a 90/10 (Argon/Carbon Dioxide) gas mix for welding in the shop and then have a variety of stick electrodes for welding outside or on stainless steel.

To weld aluminum, opt for a Spool Gun setup and run 100% Argon.

Why should I TIG weld when I can MIG or Stick weld?

TIG welding is usually reserved for very precise welding or where the highest quality of weld is necessary. Often it is much easier or quicker to MIG weld or stick weld.  Personal preference is a factor.

Most find that MIG welding is the preferred method of welding since it’s fast and easy.

Some welders also prefer stick welding as it’s more portable and better for field repairs on dirty or rusty material. Stick welding is also very versatile as you can easily weld steel, stainless steel, and cast materials with a quick change of the electrode.

What type of gas should I use for TIG welding?

It depends to some extent on base metal and thickness but most TIG welders will use 100% Argon.

Do I need a foot pedal for TIG welding?

No, but you may find it helpful. The TIG pedal hooks up to the Forney MP machines by way of the 7 pin Amphenol style connector and allows the user to “remotely” control the welding arc and current.  If you use a foot pedal, the machine would need to be switched from local to remote.

How does the TIG setup work on the MP welding machines?

You can use the Forney TIG torch or any 17V style torch with a size 25 dinse style connector.  The MP machines do not have a gas solenoid for TIG welding so a TIG torch with gas valve is necessary.  The “V” in 17V indicates the torch has a gas valve.

The Forney TIG torch has a trigger that connects to a 7 pin Amphenol style connector that allows you activate the arc with the trigger.  A traditional non-trigger torch can also be used with a lift-arc technique.  The output is DC only and suitable for welding various steels, and some stainless steel.

The Forney MP machines are not A/C, pulse, or high frequency capable so welding aluminum is not recommended.

If I use Forney Easy-Flow brazing rod, how strong will the joint be and what type of flux I should use? Will the joint be as strong as JB Weld epoxy? Can I do better with aluminum rod?

The Easy-Flo Brazing rod (Forney ITEM# 46111) is a self-fluxing rod. The “as brazed” tensile strength is 35,000 PSI. This product is applied via oxy-fuel/brazing.

As for using Bare Aluminum rod, the tensile strength is lower at 29,000 psi. This product requires a flux if being gas brazed. However, the recommended application process is oxy-fuel/brazing, but it can be applied with air/acetylene or TIG processes.

Finally, refer to for information on the epoxy you want to compare. However, based on a quick review of their site it seems that the epoxy provides tensile strengths of about 3,900 psi which is ~1/10th the strength of brazing with Forney Easy-Flo.

How does the amp setting work on the Forney 190 MIG welder?

Forney ITEM #318 (190 MIG Welder) and ITEM# 311 (210 MIG Welder) both have a six tap position for voltage adjustment and infinite control over wire feed speed (WFS) which is also related to amperage. If you think of the voltage tap settings as 1/16″ thickness increments, this will help a lot.

Tap Setting related to Material Thickness that can be welded in a single pass:

  • Tap 1 = 1/16″ Material Thickness
  • Tap 2 = 2/16″ (1/8″)
  • Tap 3 = 3/16″
  • Tap 4 = 4/16″ (1/4″)
  • Tap 5 = 5/16″
  • Tap 6 = 6/16″ (3/8″)

The key to using a tapped machine is to first select the appropriate tap setting for material thickness and then vary the WFS which also affects amperage to dial in the optimum arc characteristics. Once you use this approach, you can dial in an arc very quickly.

Both the 190 MIG and 210 MIG can weld anything from thin sheet up to 3/8″ in a single pass. Thicker plate thicknesses can be welded with multiple passes.

Where can I get my Forney machine serviced?

Are there Forney parts available that would work for the Clarke 100EN MIG welder?

We do have parts available that would work:

Would the Forney 180FI gun work on my Clarke 190EN MIG welder?

Unfortunately, we don’t have schematics for the Clarke 190EN welder to confirm or not the 180FI gun will work. We sell these as a torch and gun assembly under our ITEM# 85263 if you’d like to give it a try. To order this product, you’ll need to contact our Customer Service team.

The argon supply line on my welder is 1/8″ O.D. tubing. I purchased a regulator that has a barb supplied, but the barb is for a 1/4″ O.D. line. How do I connect the small line to my regulator?

If the regulator and barb were Forney products, we do have an adapter, ITEM# 85359 that will work for the connection. It’s a quick connect device that the gas line goes inside of. To order this product, you’ll need to contact our Customer Service team.

Does your Forney #85359 MIG welder gas adapter fit a Clarke gas regulator WE6540?

Yes, ITEM# 85359 will fit the Clarke WE6540 regulator. To order this product, you’ll need to contact our Customer Service team.

Where can I find a replacement capacitor for my old Forney C3 AC welder?

Those capacitors are 370V. A couple of places where you might find them are:

  • Galco Industrial Electronics (800) 575-5562
  • Packard, Inc. (800) 334-1769

What types of metal I can weld with on the Forney 180FI?

  • ALUMINUM: For welding aluminum, an aluminum wire will be required as well as gas. Argon will need to be used in this application.
  • STAINLESS STEEL: For stainless steel, likewise a stainless wire will be required. You can use either argon or CO2 on this wire.
  • MILD STEEL: Mild steel flux core wire is best for thin gauge mild steel and doesn’t require the use of a shielding gas, although it can be used. Mild steel wire does require the use of a shielding gas. You can also use either argon or CO2 on this wire.

Is there a manual for the Forney Spitfire model #225, 225 amp, style #JE831191?

Do you carry a tip that would fit a Hobart H-9A gun?

Yes, Forney ITEM# 60165. It comes as a 3-pack.

I need a tip for the Tweco style gun on a Clarke 180EN WE6524 – do you carry a part for this?

We offer two 4-packs of contact tips:

We also offer an ITEM# 85316 shield gas nozzle.

What are the combinations the rocker switches on the Mini MIG 135 give for output?

With left being the ‘off’ position and the sequencing being top then bottom switch, the lowest to highest voltage would be as follows:

  • off off
  • off on
  • on off
  • on on

Is the Mini MIG 135 still available?

Unfortunately, that machine has been discontinued. You can see our current line of MIG welders here:

Why does the wire on the Forney 95FI 120V flux cored wire welder arc when it touches the weld piece?

A unique feature on that specific economy welder is that the gun is ‘live’ whenever the welder is ‘on’. So the best safeguard against undesired contact would be to have a piece of non-conductive material on hand to rest the gun on between welds when the machine is on.

What size wire should I use to make a 150 foot extension cord for my 130 MIG welder?

We would recommend using 10/3 wire to be able to access the higher amperage available on that machine. However, we do not recommend extension cords longer than 25 feet.

Where can I purchase a AT-100 welder?

Unfortunately, that item was discontinued. You may be interested in some of our newer machines.

Where are Forney welders made?

Forney welders are made to our specifications at a state of the art plant in Italy. The same plant produces the MIG welders offered by other large retail chains.

I use an ARC welder on heavy equipment. What type of electrode should I be using?

The rod recommended would be determined by a number of factors: load stress on the weld, condition and type of base metal, anti-corrosion or hard-surfacing requirements, etc. Without any of this information, we can’t make a solid recommendation. You may want to refer to the product descriptions found in our line of electrodes:

What type of electrode would you recommend for cast iron (1955 Willy’s Utility Wagon exhaust manifold flange)?

Welding on cast iron requires the part to be preheated. If the part isn’t preheated (and even if it is but doesn’t get hot enough) the application of the electrode will generate heat and when that hits a cold spot will crack the cast iron, further compounding the issue.

If you opt to go ahead with the welding, we recommend our 55% Nickel “Super Ni-Cast” rod, or our Super NI-Cast 99% Nickel. The 55% has a higher tensile strength and typical applications are Grade 30, 40, and 50 cast iron, and the 99% indicates a typical application would be engine blocks. See our entire line of cast iron electrodes here:

Another option would be to drill the holes out, tap them, and put a threaded insert in. The stud could then be threaded into that and would eliminate the need for the welding. Your local parts store should be able to assist with that if that’s the way you decide to go.

Where can I find a 10′ torch replacement assembly for the Clarke 220 volt wire feed welder?

Forney ITEM# 84909 would be a suitable replacement. To order this product, you’ll need to contact our Customer Service team.

Where can I find a complete replacement gun for Clarke 130 EN MIG welder, including the gun liner etc.?

Forney ITEM# 85263 would be a suitable replacement. To order this product, you’ll need to contact our Customer Service team.

Do you have any brazing and soldering tips?

Can I use the Forney light duty oxy fuel torch set (ITEM# 1680) with propane if I change the tip?

You may use propane with the other components in the set.  The only difference is that propane will dry out the O-rings on the torch and handle, the diaphragm on the regulator, as well as the hose quicker than acetylene will.

Can you tell me the composition by percentages of Forney ITEM# 38106?

Lead is shown on the Safety Data Sheet (SDS) as 80 – 100%, Tin is between 1 and 5%, and Metal between 1 and 5%.

You can also see the SDS on the product page here:–general-purpose-repair–solid-core–1-8–16-oz

Why your cylinders are stamped with UN/ISO instead of DOT standards?

It’s essentially the same standard, except the UN/ISO standard is globally recognized (including by the USDOT) instead of just being recognized in the US/Canada.  The bottom row of the stamping on our cylinders contains the UN/ISO standard stamp. There should be no issue on the fill station filling our cylinders based off the UN/ISO stamp.

Would the Forney ITEM# 86152 make my Italian Walkover torch kit work with American gas tanks? The nipple on my hose is currently too big to connect to disposable propone/O2 tanks.

Forney ITEM# 86152 is not recommended for this purpose. We recommend that you purchase a 1/4″ or 3/8″ hose as a possible alternative.

Where can I find the fine tune screw for a Forney cutting torch SA5870?

Unfortunately, we don’t stock this part. You may with to check with your local gas supplier.

Do you have spark starters?

Where can I get adapters for UK oxygen acetylene tanks to a United States Victor cutting torch?

Unfortunately we don’t carry the adapter you require for your conversion. Check with your local gas supplier.

How do I replace the swan neck liner O-ring on a Forney® #00306 & #00308?

The first step in removing the swan neck liner is to open the gun case. Be careful, because it will have to go back the same way. The electrical wire routing is important if you want to close the case tight again. Make a note of how the trigger assembly works. Do not lose the hinge pin for the trigger. Try to lift the aluminum gas block out of the case without disturbing anything else. You need to get access to the set screw near the end of the gas block next to where the swans neck enters the gas block.

Loosen the set screw. While holding the gas block, twist the swans neck back and forth and pull at the same time. It should not take much effort to remove the swan’s neck. Inside is the short liner sometimes with a rubber o ring. I have found that that o ring can cause problems, causing the wire to catch at that point. My advice is to remove that o ring before you insert the new wire liner. The funnel shape on the end of the liner goes toward the gas block and fits in a recession at the end of the swan’s neck hole in the gas block. The swans neck is inserted into the hole until it bottoms out.

Make sure the neck is pointed in the same direction as it was before you removed it. Re-tighten the set screw and put the gun halves back together.

Be sure you check the trigger wiring to make sure the connectors are together firmly and the trigger has a lip that must go inside the gun housing. If you find that the halves of the gun do not go together, tightly rearrange the wires and there is a ledge on the cable shield that must be in the correct position.
