Forney Easy Weld 100 ST FAQ’s

Q: Why is my Forney Easy Weld 100 ST not welding correctly?
A: Here are a couple of common issues:
- Electrode choice: We recommend the Forney E6013 & E7014. These Forney electrodes will perform well up to 1/8″; other brands may require more amperage. An E6011 electrode can also be used. Some types of electrodes like E6010 and E7018 require higher amperage and may not be the best choice for the Forney Easy Weld 100 ST. 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 feet, or a 12 gauge no longer than 25 feet. A small gauge extension cord like 14 or 16 gauge will choke the incoming power and reduce your power output resulting in inconsistent performance.
- Proper grounding: The ground should not be attached to painted or coated metal.
Q: Does this machine come with cables and electrodes?
A: It does come with the ground clamp and electrode holder. It does not come with any sample electrodes. We recommend Forney E7014. This machine can weld 3/32” and 1/8” in E7014.
Q: I only see a dial that goes to 80. not 90. so why does it say 90 amp?
A: This welder utilized Hot-Start technology which delivers an extra 10 amps when starting a weld. This feature helps prevent electrodes from sticking to the base metal.
Q: What amp breaker do you need?
A: For this machine you will need to have a 15-20 amp breaker.
Q: Will the 100 ST run 7014?
A: Yes, as long as the rod does not exceed an 1/8 in.
Q: Does this machine have a plug for the argon gas?
A: This unit does not have gas capabilities for an Amphenol plug for foot pedal control. For TIG, this machine would be constant amperage and you would need a TIG torch with a gas hose like Forney part #85657. Also, because this machine is DC output only, it will not TIG weld aluminum.
Q: Does this welder require a pure sine wave input, or can I run it on a modified sine inverter?
A: A modified sine wave inverter should work, however it might not deliver the best performance. It could also lower the life of the machine.
Q: What wattage and amp generator would be needed to run this?
A: to ensure the full capacities of the welder, you would need about 8000 watts. The rated input amperage for the welder is 25A.
Q: Does this welder come with the 110 plug?
A: Yes, this welder has a 110 plug hardwired into the back of the machine.
Q: Is this welder running DC or AC power for welding?
A: This is a DC output machine.
Q: Can I use 308 or 309 rods?
A: Stainless steel rods will work just fine with this machine
Q: Will a Forney Easy Weld 100 ST burn 6010 stick weld rods?
A: Yes, this machine will weld 6010 just fine!
Q: My Forney Easy Weld 100 ST is sticking. I tried adjusting it to the highest scale and I get the same result.
A: Make sure you have an extension no cord longer than 25 ft. long. In addition, be sure to check your electrodes. If your electrodes are too big it could cause the machine to seem like it can not weld because it does not have enough amperage. We recommend using 3/32-1/8 dia. electrodes.

Forney Easy Weld 125 FC FAQ’S

Q: Why is my Forney Easy Weld 125 FC not welding correctly?
A: Here are some common issues:
- Wire feed tension: Check the tension on the despooler. Is it set too tight or is the wire feed tension not set correctly?
- Wire choice: Are you using .035” wire? We recommend .030″ for best performance.
- Stickout: Is your stickout too long? Your stickout should be no more than ½”. Here’s a short video on determining stickout.
- Pull the trigger: To begin welding, pull the trigger on the MIG gun.
- Proper grounding: The ground should not be attached to painted or coated metal.
Q: Is machine AC or DC welding output?
A: This is an AC unit
Q: Is there a dedicated flux core nozzle available for this welder?
A: Unfortunately there is not a dedicated flux core nozzle that we sell for this welder.
Q: How much does this machine weigh?
A: The welder itself weighs approximately 33 lbs without the packaging.
Q: Do I need an adapter for a 10 lb spool?
A: For the 125 FC you do not need an adapter for a 10 lb spool. The spool should fit into the machine as is.
Q: Does this machine use gas?
A: No, it does not use gas.
Q: Will this machine weld horse shoes to rebar (for yard art)?
A: Using this machine for yard art purpose on material such as horse shoes and rebar would be perfect for the 125FC. It is only capable for flux core wire so there might be additional clean up, other than that it will do great!
Q: Does this machine come fully assembled with wire set up in it already?
A: It comes with a roll of wire but it not already fed through the machine.
Q: Does this machine weld stainless steel?
A: This 125 FC machine is a mild steel flux core welder only. In order to weld stainless steel you must have a gas input to get the weld you need. With our stick machine (298) which is in the same price range you can get a stick electrode (E312-16) that will weld stainless steel.
Q: Can I use an adapter plug from 120V to 240V?
A: This machine only requires 120V it will not run off 220V.
Q: How long is the torch lead?
A: The torch lead on this is 7ft long.
Q: Can you use .035 wire in this machine?
A: You “can” but we strongly recommend against it. You will have a much better experience with .030 wire or smaller. The amp output of this machine is better suited for smaller diameters. Thicker wire will seem to run “cool.”
Q: Will this machine be good for auto collision repair? If not, what do you suggest?
A. This machine is an AC transformer machine and works great for sheet metal and thin plate. Although there is more clean up because of the weld characteristics of the transformer machine. Our new Forney Easy Weld 140 FC-i is a flux core unit as well but may leave less to clean up because of the inverter technology. If the clean up isn’t a concern either machine works fine.
Q: What is the thinnest steel I can weld with this machine?
A: 18 gauge steel (.048 in) is the minimum recommended thickness for this machine.
Q: Is the 125FC compatible with a spool gun?
A: The 125 FC is not compatible with a spool gun.
Q: Can this machine weld titanium?
A: Unfortunately, no.
Q: What is the duty cycle of this machine?
A: This machine is 20% at 80A
Q: Can this machine weld aluminum?
A: This unit is a flux core welder only. This means unfortunately there are no inputs for any kind of gas. In order to weld aluminum you need the capability of using Inert gas.
See which one of our machines can weld aluminum here.
Q: Does this welder work off normal house current?
A: The 125 FC does work off “normal” house power as long as you have a dedicated circuit and at least a 15AMP breaker on the outlet you will be using.
Q: Is this an inverter MIG machine?
A: This is a transformer flux core machine with an AC output.
Q: Does this machine have a trigger activated arc or is the contact tip always hot?
A: The trigger must be pulled.
Q: Does the manufacturer cover warranty if I use .035 flux core?
A: The warranty does cover your machine if you use an .035 but, this machine works much better with an .030 wire because of the limitations of this machine.
