· Maintaining a proper welding procedure · including pre-heat and interpass temperatures · may be critical depending on the type and thickness of steel being welded.

· See Above: This information was determined by welding using 75% Ar/25% CO2 shielding gas with a flow rate between 35-50 cfh (17-24 l/min). When welding using 80% Ar/20% CO2 shielding gas, reduce voltage up to one volt.

· All positions include: Flat, Horizontal, Vertical Up, and Overhead.

STORAGE
