Features of MIG welding wire ER70
ER70S-6 is a kind of mild steel copper coated welding wire, suitable for 100% CO2 and Argon& CO2 mixed gas protective welding with stable feasibility, good welding seams, less spatters and excellent welding process properties.
Application for MIG welding wire
Used to weld ship building steel(A,B,D,E,A36,D36,E36)and equivalent mild steel or 550Mpa grade mild alloy steel, such as container building, construction machine, railway construction, pressure vessel for semi-auto or automatic gas shielded welding.
1. Wire into the plant must be stored in dry conditions, can not open welding wire coil waterproof packaging.
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 welding protective gas flow rate should be controlled at 20~25L/min.
5. Wire extension length should be controlled in the range of 15~25mm.
