carbon steel flux cored welding

A5.20, CARBON STEEL Flux Cored Arc Welding Electrodesis a self-shielding flux cored wire
Standard: AWS/A5. E71T-GS delivsers best arc characteristics for gas-shielded flux-cored welding Shipbuilders and structural fabricators like it because it runs well. It’s our best running E71T-1 for high argon gas blends,and it delivers great arc stability and fast freezing slag for easy out-of-position welding,even with 1/16 diameter wire. This wire is carefully protected from moisture contamination using the vacuum-sealed foil bag packaging.
