2. Connect TIG torch and ground clamp | 3. Connect TIG torch lead to gas (100% Argon)  |
4. Adjust amperage per material thickness | 5. Connect to input power | 6. 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 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 |

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. | |

The 2 knobs are both twist and momentary push buttons. Does toggling the left hand sided knob (the one that adjusts the amperage) have a function? Does the Forney 220 AC/DC have a way of adjusting pre and post gas flow?
Hi Gabriel,
The knob that controls the amperage does not have a function when toggled. Also the unit does not have adjustable pre/post flow, the software of the machine determines optimal pre/post flow based on the input settings. Thanks for reaching out!
