Flux Cored Wire E71T-GS
Flux Cored Wire AWS A5.20 E71T-GS is an all-position, self-shielded flux-cored wire designed for single pass fillet and lap welding on galvanized or carbon steel as thin as 20 gauge, without burn-through. Gasless Wire E71T-GS is commonly used on small portable 110 volt welding machines, offering smooth arc action with very little spatter. Travel speed is fast, penetration is good and slag removal is easy.

Application
AWS A5.20 E71T-GS is a self-shielding all position flux cored welding wire for single pass applications. The use of DC straight polarity minimizes the risk of burn through. It is excellent on lap and fillet welds on thin mild steels.
E71T-GS is most popular for the home workshop welder because it works so well on 110 volt machines and can be used on such thin gauge steel. Gasless Wire E71T-GS is used quite extensively in automobile bodyshops for door or body repairs and it is also used for sheet metal duct work on lap and butt joints.
