STANDARD DIAMETERS AND PACKAGES: 

For a complete list of diameters and packaging, please contact

• 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% Argon (Ar)/25% Carbon Dioxide (CO2) shielding
gas with a flow rate between 35-50 cfh (17-24 l/min).
• All positions include: Flat, Horizontal, Vertical Up, and Overhead.
