LT*ER70S-6 0.8/1.0/1.2/1.6mm Cooper Coating CO2 Mig Welding Wire
Features and Applications:
ER70S-6 CO2 Mig Welding Wire is a premium carbon steel electrode formulated for welding carbon
steels with a yield strength range of 55,000-70,000 psi. ER70S-6 is well suited for steels containing medium to high levels of mill scale and mild amounts of contaminants. The wire’s copper coating promotes excellent feeding characteristics.
ER70S-6 CO2 Mig Welding Wire is a good selection for weldments requiring better tie-in and wetting than possible with a 70S-3 electrode. It is a terrific choice for welding pressure vessels,structural steel, pipe, steel buildings, and automotive repair.
CHARACTERISTICS:
1. Has higher manganese and silicon for improved performance over scaled plate.
2. Excellent feedability and welder appeal.
3. Extremely stable and consistent arc transfer.
4. Achieves high wire feed speeds without problems.
