Get started with the Forney Easy Weld 140 MP! This is a breakdown of the Quick Start Guide that is included with your new machine.

MIG Welding With the Forney Easy Weld 140 MP

MIG Gun; 140 MP; Ground Clamp

FIRST STEPS

1. Read User Manual

2. SelectMIGprocess.
Process selector switch

3. Set polarity for MIG (Solid wire) or Flux-cored.
Solid WireFlux-cored

4. Connect MIG gun and ground clamp.

5. Install wire spool.

a. 0.023” (0.6mm) - 0.030” (0.8mm) diameter
8” (200mm) wire spool
4” (100mm) wire spool

6. Set drive roll.
Solid wire; Flux-cored; *Face the appropriate groove towards the inside of machine

7. Feed wire and set pressure.
Pressure knob; Knob set ~2-3 marks

8. Connect to Input PowerInput Power symbol

a.Generator OK with continuous output > 4,000 W

b.Extension cord: #12 AWG or larger; 25’ (8m) or shorter
120VAC, 20A outlet, 30A breaker recommended

NOTE: If using gas:

i. Attach gas hose to machine

10. Adjust wire feed speed (wire feed speed) and voltage (voltage). See chart on welder for correct settings.adjuster knobs 

11. With contact tip 1/4" from metal, depress trigger completely to initiate arc.MIG trigger

 

MIG Troubleshooting Tips

Both LED lights off

  • Verify machine is plugged in and on. See manual.
    LED lights off

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

  • Not recommended for this machine.
  • Requires more amperage on MIG than this machine is designed to output.
    Aluminum welding not recommended

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.
    Ground and clamp

Frequently tripping circuit breaker or exceeding duty cycle

  •   Use wire with a diameter between 0.023” (0.6mm) and 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.
    Correct; Wrong

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
    Knob set ~2-3 marks

No arc start on contact

  • Trigger must be pulled to initiate the arc. This will initiate the arc and begin feeding the wire.MIG trigger 
    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.

6. Connect to Input PowerInput Power symbol

a.Generator OK with continuous output > 4,000 W

b.Extension cord: #12 AWG or larger; 25’ (8m) or shorter
120VAC, 20A outlet, 30A breaker recommended

7. Initiate the arc with a scratch or lift technique when in contact with the metal.

a. Electrode is always electrically hot while in TIG mode

Frequently tripping circuit breaker or exceeding duty cycle

  •   Use 1/8” diameter electrodes or smaller. Some 1/8” may draw too much amperage.
  • Trying to weld single pass on material larger than ¼” thick is not possible with this machine. Multi-pass recommended for thicker materials.
  • Welder should be the only thing plugged into the circuit.
