Features

  • ER70S-6 MIG WIRE: It's the most common wire of the copper-coated mild steel GMAW (MIG) wires for single or multiple pass welding.
  • SHIELDING GAS: ER70S-6 welding wire can be used with 100% CO2 or a mixture of 80% Ar and 20% CO2 as shielding gas. Make sure to choose a wire that is compatible with the shielding gas you'll be using.
  • EXCELLENT PERFORMANCE: ER70S-6 has the highest combination of manganese and silicon deoxidizers, permitting higher welding currents with 100% CO2 shielding gas and leaving a smoother weld bead with little to zero post-weld cleanup. It is suited for application of sheet metal on high welding current without burn through.
  • VERSATILE APPLICATIONS: This welding wire is commonly used for a wide range of applications, including construction work, farm implement fabrication, shaft buildup, tanks, truck bodies, and general shop applications with poor fit-up or rusty, oily plates. It is also great for automobile body repairs, steel structural works, earthworks, and construction works.
  • STRONG SPOOL: The wire is supplied on a robust spool constructed from a new ABS plastic material. This spool is highly durable, tough, and anti-fragile, ensuring it withstands the rigors of transportation and operates flawlessly within the welding machine.
  • SPECIFICATIONS: Weight: 10lbs(4.5kg)/Diameter: .035''(0.9mm)

  • Great value wire
Size: 10LB Color: .030"
Great great price compared to big box stores. Has worked great in my welder and makes beautiful welds

  • As expected
Size: 2LB Color: .023"
Runs fine through my Yes welder. Would buy again.

  • Good wire, good price.
Size: 10LB Color: .035"
We do a lot of welding, unless I need something to run super smooth for some reason (hydraulics) I run this wire. Fraction of the cost, never a problem. Will high dollar name brand run a little smoother yes, more noticeable in flux core. I easily run a couple hundred pounds of yes welder wire a year. To notice the difference in name brand vs this, you'll need an expensive welder and be a little better than the weekend warrior. Don't hesitate buy it you will not be sorry. Keep the extra money in your pocket. ... show more

  • Flux core wire

It’s good wire as far as a amateur goes

  • It’s decent but not for me
Size: 2LB Color: .035"
It works okay but not like I want it too. I’ve switched to the atlas brand after running 2 rolls of this and I like atlas better. My beads are better and it adjusts very well when I adjust my settings.

  • Surprisingly Good
Size: 2LB Color: .030"
Was skeptical about buying some off brand welding wire but this one has surprised me. Lays down good, weld is consistent, not much I can complain about. Would buy more when needed

  • Great Value
Size: 10LB Color: .030"
Have used this wire over the past 2 years and it’s great quality and value for the money especially compared to what they charge at the big box stores.

  • This Product Performs Well
Size: 10LB Color: .030"
The wire welds clean and feeds smoothly. I did not test the claims that the white plastic spool is stronger.
