|
Usage Specifications
|
|
|
SM-70 is a copper coated 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. It is supplied on 5 & 15 kg Precision Layer Wound Spools, or in 250 - 300 kg Tangle free Max-Pac’s.
