CLASSIFICATION：
GB ER50-6/ISO 14341-B-G6/ AWS ER70S-6
DESCRIPTION：
ER70S-6 is 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. The wire is supplied in precision layer winding on plastic spool.
FEATURES：
High capability on oiled and oxide parent metal, low stometal sensitivities. Forming well, less welding spatter, Stable arcing, arcing 99% under low current welding with 0.8 wire
