STARBlaze E70S2 MIG Welding Coil is a solid mild-steel welding wire designed for MIG/GMAW welding applications. ER70S-2 is a triple-deoxidized wire containing aluminum, titanium, and zirconium, which helps produce clean, stable welds and provides good performance when welding mild and carbon steels, including surfaces with some rust or mill scale.

It is suitable for structural fabrication, pipe welding, general engineering, workshops, and industrial welding applications. The wire supports smooth feeding, good puddle control, and low-porosity weld deposits when used with appropriate shielding gas and welding parameters.
