E71T-1 Flux Cored Welding Wire
1. Excellent welding performance, soft and stable arc.
2. Low spatter loss, easy slag removal, Beatiful appearance of weld and high X-ray safty
3. Rutile type flux cored wire of 490Mpa high tensile steel
Instruction
1. Gas- Shielded:100% CO2 OR 75% Ar 25% CO2
2. When welding, the gas flow rate shoule keep between 15L/min and 25L/min
3.The oil stains and rust on the welding should be cleared away.
