10401930 - Tweco Classic 4 MIG Gun 400A 15ft Lincoln Connection

The VELOCITY2 Classic No. 4 0.035" - 0.045" 400 AMP MIG Guns are designed with innovative features inspired by welders, making them the industry standard for over 40 years. These air-cooled MIG guns are suitable for heavy duty fabrication. With a solid copper conductor path and optimized electrical surface contact, they offer exceptional performance and efficiency. The VELOCITY2 Consumables require fewer connections and parts, resulting in a lower cost of ownership. The gas ported velocity2 contact tips stay cooler and have a longer lifespan. Additionally, the velocity2 tips are easy to use and do not require any tools for installation. They can also be rotated to prolong their lifespan, reducing the need for frequent changes. The centered liner with the conduit liner fitting inside the tip ensures excellent wire feed ability. Welding with these MIG guns provides a smoother and more stable arc, resulting in superior welding performance. The large copper to copper surface contact further enhances thermal and electrical efficiency. These MIG guns have proven to significantly improve contact tip life for various wire types, with solid wire lasting 2 to 3 times longer, spray transfer lasting 4 to 5 times longer, and gas shielded flux core lasting 8 to 10 times longer.
