Applications

Characteristics on Usage

SM-70 is a solid wire designed for all position welding by short-circuiting type

transfer. As the deposition efficiency is high and penetration is deep, highly efficient

welding can be performed.

Notes on Usage

1: Use welding grade CO2/Argon+15~25% CO2

2: Flow quantity of shielding gas should be 25 /min. approximately.

3: Use wind screen against wind.

4: Keep distance between tip and base metal 6~15 mm for less than 250A,

and 15~25 mm for more than 250A of welding current .
