Get started with the Forney Easy Weld 140 FC-i! This is a breakdown of the Quick Start Guide that is included with your new machine.
FIRST STEPS
1. 
Read User Manual
2. Install wire spool
a. 0.030” (0.8mm) diameter
3. Set drive roll
a. Face the side marked 0.030” away from the machine
4. Feed wire and set pressure
a. For proper tension align the tops of the screw and nut together
5. Connect to Input Power 
a. Generator OK with continuous output ≥ 4,000 W
b. Extension cord: #12 AWG or larger; 25’ (8m) or shorter
6. Remove consumables and depress trigger until wire comes out. Replace consumables.
7. Adjust wire feed speed (
) and voltage (
). See chart on welder for correct settings.
8. With contact tip 1/4″ from metal, depress trigger completely to initiate arc.
MIG Troubleshooting Tips
Both LED lights off
- Verify machine is plugged in and on. See manual.
Both LED lights on
- Duty cycle exceeded or insufficient air flow. Allow machine to cool. Ensure vents are clear of obstacles. See manual.
Aluminum welding
- Welding aluminum requires shielding gas. This machine is only for gas-less flux-cored welding.
- This machine cannot connect to a spool gun, which is recommended for aluminum.
Workpiece grounding
- Connect ground clamp to clean, bare metal. No rust, paint or other coatings. Attach the ground clamp directly to the work piece if you are experiencing issues.
Frequently tripping circuit breaker or exceeding duty cycle
Use wire with a diameter of 0.030” (0.8mm). Larger diameters draw too much amperage. 
Trying to weld single pass on material larger than ¼” (6mm) thick is not possible with this machine. Multi-pass recommended for thicker materials. 
Welder should be the only thing plugged into the circuit.
Low weld output or poor fusion
- Usually due to low input power.
- Welder should be only thing plugged into circuit.
- Avoid using extension cords. If one must be used, it must be #12 AWG or larger; 25’ (8m) or shorter.
- Generators must be 4,000 W continuous output and not have a low-idle function (or have it disabled).
Improper wire spool installation
- Can cause feed issues and inconsistent weld quality.
- Verify all parts are in the proper place. Refer to manual.
Too much spool tension
- Wire from spool to drive should relax with a slight curve after feeding.
Incorrect drive roll pressure
- Too little pressure = Roll can slip and feed can be erratic
- Too much pressure = can crush wire, causing wire feeding problems and welder damage
No arc start on contact
- Trigger must be pulled to initiate the arc. This will initiate the arc and begin feeding the wire.
- DEPRESS THE TRIGGER COMPLETELY
Mismatched drive roll, liner, or contact tip size
- Can cause feed and weld issues and arc instability.
- Each component must be sized for wire diameter used.
