- Applications
- Butt and fillet welding of vehicles, buildings, ships, machinery, etc.
- Characteristics on Usage
-
- - WM-70A is a solid wire designed for all position welding and high speed welding of steel sheets can be performed easily by short-circuiting welding.
- - Arc is stable and spatter loss is low.
- Notes on Usage
-
- - Shielding gas should be used Ar+20~25%CO2.
- - Use wind screen against wind.
