Select 70S-6 Close Window
 Print Sheet


CLASSIFICATION: ER70S-6 per AWS/ANSI A5.18, ASME SFA 5.18

This premium carbon steel, "MIG wire", electrode is formulated for welding carbon steels with a yield strength range of 55,000-70,000 psi. Select 70S-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.

APPLICATIONS: Select 70S-6 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.

DIAMETERS: .035", .045", 1/16"

SHIELDING GASES: 100% CO2, 75-95% Ar/ balance CO2, 95-98% Ar/ balance O2, 30-50 cfh

WELDING POSITIONS: All Positions

CHARACTERISTICS:

  • Has higher manganese and silicon for improved performance over scaled plate.
  • Excellent feedability and welder appeal.
  • Extremely stable and consistent arc transfer.
