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 gas shielded products, but the benefits of not having to use gas makes this product extremely popular. E71T-GS operates on DC current only. Make sure your power source is set properly for a good, non porous weld.
