Copper Coated

JACKSUN MIG 45

AWS/ASME: A5.2 RG45

JACKSUN MIG 45 is a copper-coated low-carbon steel welding rod designed primarily for oxy-acetylene (gas) welding and brazing applications.
Suitable for welding mild steel sheets, plates, and pipes up to medium thickness.
Excellent for general fabrication, sheet metal works, and auto body repair.
Produces soft, ductile weld deposits with good machinability.
Can be used without flux for clean, controlled welding.
