Welding Parameters
Current Type: DC Electrode Positive
| Volts | Amps | Diameter | Stick Out |
|---|---|---|---|
| 30-31 | 300- 310 | 1/16" (1.6mm) | 1" (25mm) |
| 26-32 | 250-450 | 3/32" (2.4mm) | 1¼" (32mm) |
| 30-38 | 450-750 | 1/8" (3.2mm) | 1½" (38mm) |
Welding Procedure:
Gas Cover Options (for all wire sizes):
75/25 Argon/CO2, 80/20 Argon/CO2, 90/10 Argon/CO2, 98/2 Argon/CO2. Slow cooling after welding is extremely important to reduce stress build-up and minimize the risk of cracking. Therefore, using this wire requires a minimum of preheat from 600-800 °F (315-427 °C) depending on size of the part and composition of the base metal. Throughout welding operation, limit interpass temperature to 900 °F (480 °C). After welding, the part should be returned to the preheat furnace to allow the temperature throughout the part to equalize.
