| GTAW “Tig Process” | |||
| Wire Diameter | Amps DCSP | Volts | Shielding Gas |
| .035 | 60-90 | 12-15 | Argon 100% |
| .045 | 80-110 | 13-16 | Argon 100% |
| 1/16 | 90-130 | 14-16 | Argon 100% |
| 3/32 | 120-175 | 15-20 | Argon 100% |
Note: Parameters for tig welding are dependent upon plate thickness and welding position.
Other shielding Gases may be used for Tig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration.
