Item Details

  • Lincoln Electric® Super Arc® L-50 ER70S-3 Carbon Steel MIG Welding Wire featuring exceptional arc characteristics is a good choice for broad spectrum of single-pass sheet-metal welding applications. Welding wire with a 0.035" Dia has consistent weld deposit chemistry and is suitable for multi-pass welds on thick steel sections. It finds application in industries, farming, construction, mining equipment and also during welding pipe, pressure vessels, structural steel components. Wire with moderate levels of silicon and manganese for cleaning action is designed to be used on clean, oil-free and rust-free base material. Trouble-free performance is delivered by the wire and it comes in a 44 lb fiber spool of 12" Dia.


  • Fluid puddle, good wash in at weld toes and flat weld beads minimize defects, scrap or re work
  • Quiet, very stable arc produces less spatter, reduces clean up time and raises productivity
  • Consistent weld deposit chemistry and procedures from package to package improve quality and save time
  • Low feed forces reduce wear and tear on gun liners and contact tips
  • Excellent operator appeal no gun chatter or feeding instability
  • Copper coated for long contact tip life
  • Supports short circuiting, globular, axial spray and pulsed spray transfer
  • Moderate levels of manganese and silicon for deoxidization of clean to light mill scale surfaces
  • A solid performer for multi pass welds on thick steel sections
  • Superior feeding and arc stability
  • MicroGuard® Ultra provides superior feeding and arc stability


This Lincoln MIG wire enjoys a reputation for exceptional arc characteristics and trouble-free performance
