YESWELDER ER70S-6 TIG Welding Rod, 3/32 x 16 in – 5 lb

Overview

Meet the YESWELDER ER70S-6 welding rod, a copper-coated filler crafted for mild steel fabrication. Sized at 3/32 inch in diameter and 16 inches long, this 5 lb box is designed to support reliable welds across a range of shop projects. While it’s commonly used with TIG welding setups, the rod’s chemistry is optimized for a stable arc and consistent bead formation in mild steel applications.

Why choose ER70S-6 with YESWELDER

• Copper-coated composition helps promote smooth feeding and a steady arc, which can contribute to a cleaner bead profile.
• High Mn and Si deoxidizers enable higher welding currents when using shielding gas, helping you maintain efficiency on thicker or demanding joints.
• Bead appearance and cleanup a smoother bead with little to no post-weld cleanup may be achievable when shielding gas is properly applied.
• Versatile compatibility designed for mild and low-alloy steel, making it suitable for a variety of fabrication tasks.

Ideal uses

• Construction projects and structural frames where dependable filler is needed.
• Farm implement fabrication and maintenance, including bolt-on components and chassis work.
• Shaft buildup, tanks, and truck body repairs where the plates may be rusty or oily prior to welding.
• General shop applications that require consistent performance on mild steel with limited fit-up.

Shielding gas notes and bead quality

Shield gas is an important part of achieving the intended bead quality. The ER70S-6 formulation supports higher currents with 100% CO2 shielding gas, and a gas mix with more argon content can further smooth the bead and reduce spatter. When shielding gas is optimized for your setup, you may experience cleaner bead profiles and less post-weld cleanup.

How to use

Prepare the work area and ensure proper fit-up for the joint. Select appropriate amperage for a 3/32 inch diameter rod and maintain continuous shielding gas coverage during welding. Store the rods in a dry environment to preserve coating quality and performance.
