Verify machine is plugged in and on.
See manual.
Both LED lights off
Duty cycle exceeded or
insufficient air flow. Allow
machine to cool. Ensure vents are
clear of obstacles. See manual.
Both LED lights on
• 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).
Low weld output or poor fusion
Welder should be the only thing plugged into the circuit.
Frequently tripping circuit breaker or exceeding
duty cycle
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.
Workpiece grounding
• Not recommended for this machine.
• Output is DC only which is not recommended for TIG
welding aluminum.
