process
3. Connect TIG torch and ground clamp
4. Connect TIG torch lead to gas (100% Argon)
5. Adjust amperage per material thickness
6. Connect to input power
· Generator OK with continuous output > 5,000 W (120V) or 10,000 W (230V)
· Extension cord: #12 AWG (120V) or #8 AWG (230V) or larger. 25′ (8m) or shorter extension cords recommended
7. Choose between High Frequency (HF) start or Lift start.
ELECTRODE IS ALWAYS ELECTRICALLY HOT WHILE IN TIG MODE
TIG TROUBLESHOOTING TIPS
Workpiece grounding
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.
Frequently tripping circuit breaker or exceeding duty cycle Welder should be the only thing plugged into the circuit.
Workpiece Preperation To ensure maximum quality, always clean and prepare welding surfaces.

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.

Frequently tripping circuit breaker or exceeding duty cycle
Use 3/16″ diameter electrodes or smaller. Some 3/16″ will draw too much amperage. Trying to weld single pass on material larger than 3/8″ thick is not possible with this machine. Multi-pass recommended for thicker materials. Welder should be the only thing plugged into the circuit.
