Eagle ER70S-6 TIG Rod | Mild Steel Filler Rod

Eagle ER70S-6 TIG Rod is recommended for:

Mild steel
Carbon steel
General fabrication
Structural steel
Machinery repair
Automotive fabrication
Pipe and tubing
Maintenance welding
Industrial repair
Construction
Mobile equipment
General TIG welding

Especially well suited where smooth wetting, good puddle control and reliable mechanical properties are important.

Clean the weld area thoroughly before welding.

Remove oil, grease, rust, mill scale, paint and other contaminants where practical.

Use 100% Argon shielding gas for typical TIG / GTAW applications. Lincoln and ESAB both specify pure argon for comparable ER70S-6 TIG rods.

Operate on DC Straight [–] / DCEN polarity.
Maintain a short arc and keep the filler rod inside the shielding-gas envelope.

Adjust amperage according to base-metal thickness, joint design and rod diameter.

Eagle ER70S-6 is a carbon-manganese TIG filler rod with elevated manganese and silicon deoxidizer levels.

Those deoxidizers help improve wetting and puddle fluidity while producing a smooth, clean bead on general carbon-steel applications. Comparable ER70S-6 TIG products are widely used for general engineering, construction and fabrication.

Why Eagle ER70S-6 TIG Rod?

Excellent puddle fluidity — manganese and silicon help the weld pool wet smoothly.

Smooth bead appearance — well suited for clean, controlled TIG welding.

Strong mechanical properties — typical published ER70S-6 TIG data is around 560–580 MPa tensile strength with about 26% elongation.

Versatile mild-steel filler — useful for fabrication, construction, repair and maintenance.

ER70S-6 TIG or ER70S-2 TIG?

Choose ER70S-6 for general-purpose mild and carbon steel TIG welding, especially where good wetting and a fluid puddle are desired.

Choose ER70S-2 for applications where stronger deoxidation and very clean, high-quality TIG deposits are preferred.

In simple terms:
ER70S-6 = versatile everyday mild-steel TIG filler
ER70S-2 = more specialized TIG filler for cleaner, controlled applications
