Self-Shielding/Gasless Mild Steel Flux-Cored Wire (E71T-GS)
Smooth core gasless wire 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.
Smooth core gasless wire 71T-GS is most populat for the home workshop welder because it works so well on 110 volt machines and can be used on thin gauge steel. Gasless wire 71T-GS is used quite extensively in automobile body shops for door or body repairs, and it is also used for sheet metal duct work on lap and butt joints.
NOTE: As with all self-shielded wires, smooth core gasless wire 71T-GS does contain fluoride compounds which require more attention to ventilation when being used to weld galvanized steel. The zinc oxide formed during welding should not be inhaled as it can cause metal fume fever. When welding indoors or in an enclosed area, be sure that the ventilation is adequate.
