Lincoln Electric ED030631 Mig Wire ER70S-6 0.030 in 2 Lb

Product Description

The LINCOLN ELECTRIC ED030631 is a solid MIG welding wire in the I-56 series, classified to AWS specification ER70S-6. It measures 0.030 inches in diameter and is wound on a 2-pound spool. ER70S-6 wire carries a higher manganese and silicon content than standard ER70S-3, making it well suited for welding on mill scale, light rust, or moderately contaminated base metals where weld pool deoxidation is critical. This wire is used in gas metal arc welding (GMAW) processes and is a common choice for professional fabricators, maintenance welders, and auto body technicians working with mild and low-alloy steels.

This wire is appropriate for flat, horizontal, vertical, and overhead positions when used with the correct shielding gas, typically a 75 percent argon and 25 percent CO2 blend or straight CO2. The 2-pound spool size is well matched to light-duty production runs, field repair work, and smaller wire feed units where a 10-pound or 25-pound spool would be impractical. It works with standard MIG equipment across residential, commercial, and light industrial settings.

Key Features

• AWS ER70S-6 classification with elevated manganese and silicon for improved deoxidation on contaminated surfaces
• 0.030-inch diameter for fine-detail welds and thinner gauge mild steel applications
• 2-pound spool for compatibility with compact and portable wire feed units
• Solid wire construction for consistent arc characteristics and clean bead profile
• Suitable for use with CO2 or argon-CO2 blended shielding gas

Compatibility

Designed as an OEM-style replacement and standard consumable for MIG welders accepting 0.030-inch solid wire on a 2-pound spool. Compatible equipment must support GMAW processes and accommodate standard small-diameter spools.

Installation Notes

Installation should be performed by a qualified welder or trained technician familiar with GMAW equipment setup. Before loading the spool, power down the welder and release tension on the drive roll. Set drive roll groove size to match the 0.030-inch wire diameter and verify the contact tip is also rated for 0.030 inches. Always confirm shielding gas flow rate and connections before striking an arc.
