ER70S-6 (SG2) Non Copper Welding Wire 1.0mm 15kg metal spool K300
Non copper ER70s-6 do not have copper coated, but requires better production technology level and anti-rust oil with advanced formula.
This type of product is more eco friendly and the absence of copper on the surface of the wire leads to cleaner deposits and avoids the metallurgical risk of increased copper content in the molten pool.
Also, fewer harmful fume is created during welding with copper-free wire, which provides a safer working environment for welders.
