Strong 70S2 – Style-4
STRONG 70S-2
Copper Coated Solid Wire For MIG & TIG Welding
STRONG 70S-2 is a copper-coated carbon-manganese steel wire with tripple de-oxidizers (Ti, Zr, Al) which enhances deoxidation when welding over steels that are rusty or dirty. It is also suitable for welding thin, galvanized or electro-galvanized material with x-ray quality welds.
STRONG 70S-2 is designed for welding most carbon-manganese steels including structural steel, MS steel plates, pipes, fittings, castings and forgings. This product is also a preferred wire for all position welding of small diameter pipes.

Description
STRONG 70S-2 – Copper Coated Solid Wire for MIG & TIG Welding
STRONG 70S-2 is a premium-quality copper-coated carbon-manganese solid welding wire engineered to deliver superior performance across a wide range of welding applications. Designed for both MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding processes, this wire is known for its excellent arc stability, consistent feedability, and high-quality weld output. It is especially suitable for applications where reliability, strength, and precision are critical.
One of the standout features of STRONG 70S-2 is its unique chemical composition, which includes triple deoxidizers—Titanium (Ti), Zirconium (Zr), and Aluminum (Al). These elements play a crucial role in improving the wire’s deoxidizing capability, making it highly effective when welding over surfaces that are not perfectly clean. In real-world industrial environments, materials often contain rust, mill scale, oil, or other contaminants. The advanced deoxidizing properties of STRONG 70S-2 help to minimize porosity and ensure sound welds even under such challenging conditions. This makes it a reliable choice for both workshop and on-site welding operations.
The copper coating on the wire further enhances its performance by improving electrical conductivity and ensuring smooth and consistent wire feeding during welding. This coating also helps reduce wear on contact tips, thereby extending the life of welding consumables and minimizing downtime. The result is a more efficient welding process with stable arc characteristics and reduced spatter, leading to cleaner weld beads and less post-weld cleanup.
