W4017500 - Tweco 50mm Female to 25mm Male Dinse Reducer Adapter

Connect Heavy-Duty Cables to Compact Inverters

The Tweco Dinse Adapter (W4017500) is an essential accessory for professional welders who need versatility in their equipment setup. As welding technology evolves, many modern inverter-style welding machines are designed with compact 25mm Dinse terminals to maintain portability and reduce weight. However, many workshops and mobile welding rigs are still equipped with robust, heavy-duty welding cables featuring standard 50mm Dinse plugs. Instead of purchasing entirely new cable sets or cutting off perfectly good connectors, this adapter provides a seamless bridge between generations of equipment.

Engineered by Tweco, a leader in welding components, this adapter features a 50mm Female Dinse end on one side and a 25mm Male Dinse end on the other. This configuration allows you to plug your existing standard weld cables directly into the smaller receptacles found on portable TIG and Stick inverters. The internal components are machined from high-quality brass to ensure excellent electrical conductivity and minimize resistance, preventing overheating at the connection point during operation.

Durability is key in industrial environments, and this adapter is built to withstand the rigors of daily use. The exterior is encased in a tough, insulating rubber shell that protects the conductive metal from accidental shorting while offering resistance to oil, grease, and workshop grime. The twist-lock design ensures a tight, mechanical connection that won't vibrate loose during welding, maintaining a stable arc and safe operation. Whether you are a pipe welder moving between machines or a fabrication shop maximizing equipment compatibility, the Tweco W4017500 is a cost-effective problem solver.
