SM - 70

Classifications    AWS A5 18 / ASME SFA 5 18 ER70S JIS Z3312 YGW12
Description Applications    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    01. Use welding grade CO2/Argon+15~25% CO2
   02. Flow quantity of shielding gas should be 25 /min. approximately.
   03. Use wind screen against wind.
   04. Keep distance between tip and base metal 6~15mm for less than          250A, and 15~25mm for more than 250A of welding current.
