Copper-plated wire
Wire MIG/MAG G3SI1/G4SI1(SG2/SG3)/ER 70 S-6
Typical application:
- The source material for the middle section
and a heavy section rolling mill - Low-carbon steel welding
- Automotive repair
Basic information:
- It’s used with automatic and semi-automatic welding machines
- Can be used with protective gases (100% CO2, 80% Argon / 20% CO2)
- Can be coated with copper for better storage
