ER70S-6 TIG Welding Wire Made In China,Argon Arc Welding Wire

ER70S-3 Copper Coated TIG Filler Wire,Mild Steel TIG Welding Rod, ER70S-3 TIG Welding Rod

Primary Use: Designed for Gas Tungsten Arc Welding (GTAW/TIG) and Gas Metal Arc Welding (GMAW/MIG) on mild steel.

Deoxidizers: The silicon (Si) and manganese (Mn) content helps prevent porosity by reacting with oxygen in the weld pool, making it suitable for welding steel with mild surface contamination (mill scale, light rust). However, it has less deoxidizer content than ER70S-6.

Shielding Gases: Your information is correct. It is commonly used with:

C25 (75% Ar / 25% CO2): The most common mixed gas for GMAW.

90% Ar / 10% CO2: Provides a more stable arc and better bead appearance than C25, especially for short-circuit transfer.

100% CO2: A cost-effective option, but results in more spatter, a less stable arc, and deeper penetration.

For TIG welding (GTAW), it is used with 100% Argon.

Applications: Perfectly summarized as general fabrication for furniture, equipment, trailers, structures, etc., where the steel is clean to moderately scaled.
