MIG TROUBLESHOOTING TIPS

Verify machine is plugged in and on.

See manual.

Both LED lights off

Improper wire spool installation

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.

• 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).

Frequently tripping circuit breaker or exceeding duty cycle

Low weld output or poor fusion

• Not recommended for this machine.

• Requires more amperage on MIG than this

machine is designed to output.

Wire from spool to drive should relax with a slight curve after feeding.

• Can cause feed issues and inconsistent weld quality.

• Verify all parts are in the proper place. Refer to manual.

Aluminum welding

Too much spool tension

Knob set ~2-3 marks

Too little pressure = Roll can slip and feed can

be erratic

Too much pressure = can crush wire, causing

wire feeding problems and welder damage

Incorrect drive roll pressure

8” (200mm) wire spool 4” (100mm) wire spool

Trigger must be pulled to initiate the arc. This

will initiate the arc and begin feeding the wire.

DEPRESS THE TRIGGER COMPLETELY

No arc start on contact

• Can cause feed and weld issues and

arc instability.

• Each component must be sized for

wire diameter used.

Mismatched drive roll, liner, or

contact tip size

Duty cycle exceeded or

insufficient air flow. Allow

machine to cool. Ensure vents are

clear of obstacles. See manual.

Connect ground clamp to clean, bare

metal. No rust, paint or other

coatings. Attach the ground clamp

directly to the workpiece if you are

experiencing issues.
