E71T-GS (dull gray wire)

WELDPORN® E71T-GS is an all-position, single-pass, flux cored welding wire designed to weld carbon steel. The unique quality of this product is that you do not have to use a shielding gas.  E71T-GS produces smooth arc action, low spatter, full slag coverage, and easy slag removal. The bead appearance is not equal to a gas-shielded product, but the benefits of not having to use gas makes this product extremely popular.  * Make sure your power source is set properly for a good, non-porous weld.

Typical Applications

• Lap and butt welds on galvanized sheet metal
• Repair of automobile sheet metal
• Joining of galvanized roofing sheet metal
• Prefab building fabrication
• Tanks
• Ornamental iron
• Farm implement repairs
• General fabrication

Welding Current

(DCEN) Straight Polarity

Typical Wire Chemistry

The composition of weld metal is not particularly meaningful since electrodes of these classifications are intended only for single-pass welds. Dilution from the base metal in such welds is usually quite high.
