• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical
depending on the type and thickness of steel being welded.
• For out of position welding, short circuit or pulsed spray transfer mode must be used.
• See Above: This information was determined by welding using 98% Argon (Ar)/2% Oxygen (O2) shielding gas with a flow rate between 35-50 cfh (17-24 l/min). When welding using 85-90% Argon (Ar)/Balance Carbon Dioxide (CO2) shielding gas, increase voltage by approximately 1 volt.
