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. E71T-GS operates on DC straight polarity (DCEN). * 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
