Application
ER410NiMo wire is used primarily to weld cast and wrought material of similar chemical composition. It is recommended using preheat and inter-pass temperature of not less than 300ºF. Post weld heat treatment should not exceed 1150ºF, higher temperature may result in hardening.

| 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.
