●Maintaining aproper 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 95% Argon (Ar)/5% Carbon Dioxide (CO2) shielding gas with a flow rate between 35 -50 cfh (17-24 l/min). When welding using 75% Argon (Ar)/25% Carbon Dioxide (CO2) shielding gas in accordance with the requirements of AWS A5.20/A5.20M, increase voltage by approximately 2-3 volts.

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

STORAGE

FEATURES AND BENEFITS

●Specially formulated to be used with high-argon shielding gas mixtures (>85% argon)

Excellent low-temperature impact toughness

Fast-freezing slag

●Helps minimize the variety of on-hand shielding gases and equipment required in failities primarily using high-argon mixtures for GMAW Maintains acceptable operating characteristics and mechanical properties unlike most E71T-1 type electrodes when used with >85% argon gas mixtures.Can help lower the fume generation rate and visible smoke levels

●Suitable for use in a wide variety of critical applications

●Provides good puddle control and bead contour when welding in all positions
