Conform With: AWS A5.20 E71T-GS
E71T-GS (E71T-G) is a self-shielded flux cored wire designed for the welding of thin-gauge
galvanized and mild steels in all positions. Slag removal is easy with fewer spatters.

Applications:
Flux Cored Welding Wire E71T-1C is designed for use in welding low-carbon steel and
490MPa tensile steels. It is widely used in shipbuilding, bridges,building construction,
machinery & heavy equipment, petrochemical, pressure vessel, steel structure etc.
Attention:
1. Wire into the plant must be stored in dry conditions, cannot open wire reel waterproof packing.
2. Welding shall be removed before welding surface oil, rust, water and other impurities
3. The CO2 gas protection, CO2 gas purity 99.98%.
4.CO2 gas protective gas flow rate should be controlled at 20-25L/min.
5. Wire extension length should be controlled in the range of 15-25mm.
6. Preheating before welding to weld 150-300 ºC, 700-740 ºC tempering treatment only after.
