• 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 3 conductor #12 AWG
or larger up to 25 feet.
• Generators must be a minimum 10,500W continuous output with no low-idle
function (or low-idle off), 5% THD Max.

• Generator OK with continuous output >
4,000 W (120V) or 10,500 W (240V)
• Extension cord: #12 AWG or larger. 25’
(8m) or shorter extension cords
recommended
To ensure maximum quality, always clean
and prepare welding surfaces.
Workpiece Preparation
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
• 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 3 conductor #12 AWG
or larger up to 25 feet.
• Generators must be a minimum 4,000W continuous output with no low-idle function
