OVERVIEW

Smooth Arc and Fast Travel Speeds

Step up your welding game with the Techniweld Tru-Core MC 70C, a .052-inch metal core wire that combines the ease of MIG welding with the penetration and speed of flux core. Packaged in a convenient 33lb spool, this wire is perfect for welders looking to lay down serious metal without the hassle of heavy slag. If you are working on heavy sheet metal or thick plate, this wire offers a buttery smooth arc that wets out beautifully, leaving flat, professional-looking beads with minimal effort.

The Tru-Core MC 70C is a dream to run in the flat and horizontal positions. It is designed to minimize spatter, which means you spend less time grinding and more time welding. Because it is a metal-cored wire, you get the benefit of higher deposition rates compared to standard solid ER70S-6 wire. This allows you to move faster and finish jobs quicker, which is a huge plus for piece-work or tight deadlines. It runs on DCEP polarity and pairs best with high-argon shielding gas blends to keep the arc spray-like and stable.

Whether you are welding manually or setting up a track torch, this wire handles beautifully. It bridges gaps better than solid wire and bites through mill scale that would normally cause porosity issues. Ideal for automotive frames, heavy equipment repair, and general structural fabrication, the Tru-Core MC 70C gives you the performance you need to tackle heavy-duty projects with confidence.

FAQ

Tru-Core MC 70C meets the AWS A5.18 classification of E70C-6M.

It is designed for use with Argon/CO2 mixtures, typically 75% Argon / 25% CO2 or 90% Argon / 10% CO2.

This specific product is .052 inches in diameter.

As a metal-cored wire, it produces small islands of silicon slag rather than a full slag covering, making cleanup very easy.

Standard metal-cored wires like this are primarily designed for Flat and Horizontal positions. Vertical welding usually requires a pulsed MIG power source.

This product comes on a 33lb spool.

Yes, Tru-Core MC 70C has deoxidizers that allow it to handle moderate mill scale and rust better than solid wire.

This wire runs on Direct Current Electrode Positive (DCEP).
