Item Details

  • Hobart® Quantum Arc™ 3 ER70S-3 Carbon Steel MIG Welding Wire is copper coated and ideal for general fabrications that use CO2 or argon rich shielding gases. 0.045" Dia wire is a combination of manganese and silicon in right proportions to make short-circuiting and spray-transfer applications easy. Wire is an ideal choice for robotic, automatic and semi-automatic welding applications with wire feed speeds ranging from moderately slow to very fast. General fabrication, light sheet metal fabrication, automotive frames or structures, metal storage bins, metal furniture and railcars also finds use of this wire to a great extent. Wire can handle argon-rich mixtures like 75% argon, 25% CO2 easily and comes in a 45 lb Steel Reel™ of 12" Dia.
