• 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 100% CO2 shielding gas with a flow rate between
35-50 cfh (17-24 l/min). When welding using 75% Ar/25% CO2 shielding gas, reduce voltage by 1 volt.
• All positions include: Flat, Horizontal, Vertical Up, and Overhead.

STORAGE
