42.0001.3912 - Fronius Contec Clamping Sleeve 10-Pack

Precision Current Transfer for Fronius Systems

The Fronius Contec Clamping Shell (Part Number 42.0001.3912) is an essential component designed for the high-performance Contec contact tip system. Engineered by Fronius, this clamping shell—often referred to as a clamping sleeve or collet—plays a pivotal role in the electrical and mechanical efficiency of your MIG welding torch. It is specifically manufactured to house Contec contact tips, providing the necessary radial pressure to secure the tip in place while ensuring maximum surface contact.

In the Contec system, the interface between the contact tip and the torch body is critical. This clamping shell facilitates a superior electrical connection compared to traditional threaded designs. By wrapping securely around the contact tip, it allows for optimal current transfer directly to the welding wire. This reduction in electrical resistance minimizes heat buildup at the contact point, extending the lifespan of both the tip and the shell itself. For industrial environments where arc stability and precision are non-negotiable, using genuine Fronius clamping shells is the best way to maintain equipment standards.

This product is supplied as a pack of 10, making it an ideal choice for high-volume fabrication shops and automated welding cells where maintenance schedules require reliable stock on hand. The precision machining ensures that every shell fits perfectly, maintaining the Tool Center Point (TCP) accuracy required for robotic applications. Whether you are welding aluminum, stainless steel, or mild steel, the integrity of your torch's front end starts with the correct clamping mechanism.
