Applications:

AWS 5.20 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.

NOTE: As with all self-shielded wires, E71T-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.

Self-shielding, all-positional flux-cored wire for single pass applications. Excellent for use on thin gauges of galvanized & mild steel. Travel speed is high & weld edges are smooth. It has a smooth arc action, full slag coverage, easy slag removal & low spatter. No shielding gas is required. The use of DC straight polarity welding current minimises the risk of burn through. Deposition efficiency is higher than that of shielded metal arc electrodes.
