Product Description

Brief Overview

This ER70S-6 mild steel TIG rod is engineered for distributors stocking versatile welding consumables that perform reliably across diverse jobsite conditions. The copper coating and enhanced deoxidizer package make this rod ideal for single-pass applications where surface preparation is minimal—a critical advantage on field repairs where cleaning isn't always practical. If your customers work with structural steel or low-alloy applications, consider pairing this with stainless steel alternatives for expanded market coverage.

Key Features

  • Enhanced Deoxidizer Package: Superior wetting characteristics and flatter bead profile reduce rework and improve operator productivity
  • Copper-Coated Steel: Improved electrical conductivity and smoother arc performance
  • Multi-Gas Compatibility: Works effectively with 75% Argon + 25% CO2, 98% Argon + 2% CO2, or 100% CO2 shielding gas—versatile for different customer setups
  • Rusty Surface Performance: Formulated for single-pass welding on dirty or oxidized steel without extensive surface prep
  • Optimized for Travel Speed: Flatter bead shape enables faster deposition rates, reducing labor time
  • AWS A5.18 / DIN 8559 / EN440 Certified: Meets international welding standards for quality assurance and customer confidence

Applications & Market Position

Primary Markets:

  • Structural and mild steel repairs across automotive, fabrication, and general metalwork
  • Small-diameter tube and pipe welding
  • Sheet metal applications
  • Heavy equipment repair where jobsite conditions demand robust, forgiving wire

Why Distributors Stock This Grade: The ER70S-6 classification is the workhorse of mild steel TIG welding. Its ability to perform on unclean surfaces without sacrificing joint quality means your customers spend less time prepping and more time welding. Higher deoxidizer content translates to fewer customer callbacks for porosity or weak welds—protecting your reputation.
