The performance of the surfacing gun greatly affects the deposition rate, powder utilization rate, surfacing layer quality, and process stability. This surfacing gun body is made of one piece of die-casting, which has better insulation and sealing, ensuring high stability and safety during the surfacing process.

Consists of three parts: the upper gun body (secures the tungsten electrode and connects water/electric connectors), the lower gun body (secures the nozzle, forms the water cooling cavity, and connects lines), and the insulator. The protective gas completes gas diffusion internally to form uniform protection, while the independent powder feeding pipeline ensures a smooth, non-clogging system.

Provides high performance, high surfacing welding efficiency, excellent quality post-welding, and extended nozzle life. The unit is convenient to operate, easy to replace, small, flexible, and adaptable for manual, semi-automatic, and automatic welding processes.
