HYW ER70S-6 MIG/MAG Welding Wire is a premium copper-coated solid carbon-steel wire supplied on 10 lb, 33 lb, and 44 lb spools, with multi-roll and pallet quantities available. Its high manganese and silicon content provides strong deoxidizing power for X-ray quality, porosity-free welds — even over light rust and mill scale — with a smooth, stable arc and low spatter for clean, general-purpose fabrication.

Key Features

  • High manganese & silicon deoxidizers for X-ray quality, porosity-free welds
  • Welds cleanly over light rust and mill scale
  • Smooth, stable arc with low spatter and minimal slag
  • Copper-coated for steady wire feeding and reliable electrical contact
  • 70,000 psi tensile class — versatile general-purpose mild-steel wire
  • Available on 10, 33, and 44 lb spools, plus multi-roll and pallet quantities

Ideal Applications

  • General fabrication and structural steel
  • Automotive body, chassis, and exhaust repair
  • Heavy equipment, trailers, and farm machinery
  • Manufacturing, maintenance, and repair (MRO)
  • Single- and multi-pass welding on carbon and low-alloy steels

Tensile Strength 70,000 psi (480 MPa) min — typ. 80,000 psi (550 MPa)
Yield Strength 58,000 psi (400 MPa) min — typ. 68,000 psi (470 MPa)
Elongation (2 in / 50 mm) 22% min — typ. 26%
Charpy V-Notch Impact 20 ft·lbf @ -20 °F min — typ. 60+ ft·lbf

Available Sizes & Recommended Amperage

Diameter Recommended Amperage
.023" (0.6 mm) 30 – 90 A
.030" (0.8 mm) 40 – 145 A
.035" (0.9 mm) 50 – 180 A
.045" (1.2 mm) 75 – 350 A

Recommended amperage ranges are general guidelines; optimal settings vary with base-metal thickness, joint design, shielding gas, and welding position. Store wire in a dry location to prevent oxidation and ensure smooth feeding.
