AK-ER70S-3 (Not copper plated)

Standard: 

EN ISO 636-A: W 42 5 2Si

AWS A5.18 ER70S-3

Description: Using mixed gas as shielding gas, when low-current short-circuit tra- nsfer welding is performed, the fluidity of the molten pool and the resistance to cra- cking are extremely superior, the spark spatter is very small, the welding slag is thin and easy to remove, and it is suitable for thin plate welding that requires smooth and delicate weld bead.

Application: Suitable for single-pass or multi-layer welding, it is a widely used GMAW wire. The use of a wide range of current, high and low current welding can get beautiful weld bead.
