WEL-195234 - 25mm Dinse Adapter for Air Cooled TIG Torches 9/17

Precision Connection for Air-Cooled TIG Systems

The Dinse Plug Flow Through 25mm is an essential component for professional welders utilizing 9 and 17 series air-cooled TIG torches. Designed to bridge the gap between your welding power source and the torch power cable, this connector utilizes the international standard 10-25mm (often referred to simply as 25mm) Dinse sizing. This ensures compatibility with a wide range of compact and portable inverter welding machines that favor this smaller, yet robust, terminal size.

Unlike standard solid plugs, this unit features a "flow-through" design. In traditional setups, the gas line might need to be routed separately to a solenoid or valve on the machine face. With a flow-through Dinse, the shielding gas is routed through the center of the connector itself, allowing for a cleaner, more integrated cable management system. This is particularly advantageous in mobile welding applications where minimizing loose hoses and snag points is critical for safety and efficiency.

Constructed from high-grade brass, the core of the plug offers excellent electrical conductivity, minimizing resistance and heat buildup even during prolonged welding sessions at the upper amperage limits of 17-series torches. The exterior is encased in a durable, high-dielectric rubber boot that provides essential insulation, protecting the operator from electrical hazards while offering a comfortable grip for the twist-lock engagement. This plug is engineered to withstand the rigors of industrial environments, resisting impact, heat, and abrasion.

Installation is straightforward, typically involving a crimp or set-screw connection to the torch's power cable. Once installed, the twist-lock action ensures a positive mechanical and electrical connection that will not vibrate loose during operation. Whether you are repairing a damaged cable or building a custom TIG rig, this 25mm flow-through Dinse plug delivers the reliability required for precision gas tungsten arc welding.
