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.
