TIG TROUBLESHOOTING TIPS 

Workpiece Grounding 

Connect ground clamp to clean, bare metal. No rust, paint or other coatings. Attach the ground clamp directly to workpiece if you are experiencing issues. 
Workpiece Preparation

To ensure maximum quality, always clean and prepare welding surfaces.
Frequently tripping circuit breaker or exceeding duty cycle
Welder should be the only thing plugged into the circuit.
Low weld output or poor fusion
110-120V
• 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 5,000W continuous output with no low-idle function
(or low-idle off), 5% THD Max
Low weld output or poor fusion
208-240V
• 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 #8 AWG
• Generators must be a minimum 10,000W continuous output with no low-idle
function (or low-idle off), 5% THD Max

Workpiece Preparation

To ensure maximum quality, always clean and prepare welding surfaces.
Frequently tripping circuit breaker or exceeding duty cycle

Use 3/16″ diameter electrodes or smaller. Some 3/16″ will draw too much amperage.
single pass Trying to weld single pass on material larger than 3/8″ thick  is not possible with this machine. Multi-pass recommended for thicker materials.
