Welding Parameters

Current Type : DC Electrode Positive , DC Electrode Negative

Volts Amps Diameter Stick Out
18-24 140-200 .045" (1.2mm) 3/4"-1" (19-25mm)
22-28 170-300 1/16" (1.6mm) 1"-1¼" (25-32mm)

Welding Procedure:

When welding out of position, use .045 (1.2mm) with Electrode Positive polarity and the lower range of amperages and voltages. Weld vertical down with 3/4" (19mm) wide weave beads. A gas cover will be helpful, especially when using a constant current power source and voltage sensing feeder.
