Butt and fillet welding of steel structures such as vehicles, machinery and bridges.

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.

① Use with CO₂/Argon+15~25% CO₂gas.
② The Flow of quantity of shielding gas should be approximately 25ℓ/min.
③ Use wind screen against wind.
④ Keep distance between tip and base metal 6~15mm for less than 250A, and 15~25mm for more than 250A of welding current.
