ER70S-4 Welding Wire
Application
Welding Positions:
Notes:
1.The welding electrodes should be preheated 2 hour at 300~350℃ before welding.
2.The impurities such as rust, oil stains and moisture must be cleared off of the work piece.

Gas shielded welding wire is a kind of welding wire, also called Mag/Mig welding wire which is matched with CO2 gas or Arc gas in welding. It has strong resistance to surface scales and oil stains on the base metal. It has low blowhole sensitivity.


CO2 Gas-Shielded Welding Wire is used to welding carbon steels and 500Mpa high strength steels, used in car, building, ships and bridge. Can also be used for speed welding of sheet and pipes.
Our advantages is stable arc, little spatter, less smoke; higher deposition efficiency; excellent welding performance; easy restrike.


Applications for CO2 Welding Wire
Mainly used for welding low carbon alloy steel, widely used in industries of vehicles, bridge-engeering, machine-engeering, steel structure, shipping manufacture and contaiers.
