ER 70S-6 0.030 x 33 lb Spool AWS A5.18 Layer Wound 70S6

  • High Manganese and Silicon Content – Improves weld puddle fluidity and helps “clean” light surface rust and mill scale while welding
  • Excellent for Dirty or Slightly Rusty Steel
  • Smooth Arc Performance – Stable arc with minimal spatter
  • Good Weld Bead Appearance
  • High Strength Welds
  • Versatile Shielding Gas Compatibility – Commonly used with CO₂ or Argon/CO₂ blends
  • Layer wound to feed more smoothly through the MIG gun and reduce tangling

Description

Inweld 70S-6 contains higher levels of manganese and silicon than many other classifications of mild steel
wires. The increased Mn and Si content gives stronger deoxidizing power when welding over mild or carbon
steel that may have traces of rust or mill scale such as found on structural and plate steels.
Inweld 70S-6 is used for single or multi-pass welding. An excellent choice for sheet metal applications, where
the higher silicon content creates excellent “wetting out” properties and produces weld deposits that are essentially
flat to slightly convex and require little or no grinding. Weld deposits are x-ray quality.
