Welding Guns & Machines

Reliability for Precise Manufacturing

In demanding manufacturing environments, efficiency and reliability are key factors to keep production running smoothly. Slowdowns due to tool changes, high operating expenses, and rigid welding systems can also significantly impact productivity and profitability.

Comau addresses these challenges head-on with its new welding guns, an innovative solution designed for superior modularity, and rapid reconfiguration. The Comau all-new generation of welding guns, N-WG series, minimizes downtime, costs, and errors while maximizing welding operation performance. This enables manufacturers to achieve higher speeds, improved quality, and greater cost efficiency in their welding processes.

Comau’s N-WG welding guns represent a new paradigm in welding technology, designed with direct feedback from our customers. Our commitment to innovation and customer satisfaction is reflected in every detail, from the single body design that covers the entire range to the fast-change arm that eliminates production halts.

Comau provides a full range of standard gun arms (small, medium, large and extra-large). For specific requirements, Comau engineering supports customers in the modeling and designing of special gun arms. The 3D model shape can also be simulated and tested before the manufacturing launch to verify absolute process reliability.

This groundbreaking design ensures high-speed functionality, superior quality, cost-effectiveness, and exceptional process efficiency.
