ER70S-6 wire is a kind of mild steel copper coated wire, suitable for 100% CO2 and argon and CO2 mixed gas protective with stable feasibility, good welding seams, less spatters and excellent welding process properties. Suitable for all-position work. Diameter: 0.8 mm, 1.2mm ,Coil weight: 5Kg and 15 Kg
Wire ER70S-6 used to welding ship building steel (A , B, D, E, A36, D36, E36) and equivalent mild steel or 550Mpa grade mild alloy steel, such as container buildings, bridge building, machinery manufacturing, railway construction, pressure vessels for semi-auto or automatic gas shielded and general purposes etc.

It is typically used for single arc or tandem applications for pipe welding, pressure vessels, steel buildings and structural steel . suitable for butt and fillet welding in all positions.The Wire features great feed ability at low and high amps, longer torch consumable life – i.e. contact tips and liners, greater productivity especially for automated processes. It is excellent for mild steel and galvanized materials and safer to weld with as it produces less hazardous fumes and low spatter.It welds great with normal MIG gases.
