SM-70
SOLID WIRE
AWS A5.18 / ASME SFA5.18 ER70S-6
JIS Z3312 YGW12
l Applications
Butt and fillet welding of steel structures such as vehicles, machinery and bridges.
l 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.
l Notes on Usage
a) Use welding grade CO2/Argon+15~25% CO2.
b) Flow quantity of shielding gas should be 25L /min. approximately.
c) Use wind screen against wind.
d) Keep distance between tip and base metal 6~15mm for less than 250A, and 15~25mm for more than 250A of welding current.
