Verify machine is plugged in and on.
See manual.
Do not weld aluminum
• 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.
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.
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
FLUX-CORED TROUBLESHOOTING TIPS
Both LED lights on
Workpiece grounding
8" (200mm) wire spool
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
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.
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.
