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