92551140 - Tweco 250A Work Lead Assembly with 50mm Dinse Connector - 10ft

Reliable Grounding for Quality Welds

The Tweco 9255-1140 Work Lead Assembly is a premium grounding solution designed to ensure consistent electrical conductivity and arc stability for your welding operations. Rated for 250 Amps, this assembly is perfectly suited for a variety of MIG, TIG, and Stick welding applications found in light industrial, automotive, and hobbyist environments. A solid ground connection is critical for preventing arc wander, sputtering, and poor weld penetration, and this Tweco lead delivers the performance required for high-quality results.

Designed for Thermal Arc Compatibility

Specifically engineered as a replacement or upgrade for Thermal Arc welding power sources, this work lead features a 50mm Dinse (50D) connector. The Dinse style connector allows for quick, safe, and positive locking into the machine's output terminals, minimizing resistance and heat buildup at the connection point. The 10-foot cable length offers practical flexibility, allowing the welder to move around the workpiece without excessive cable clutter, making it ideal for bench work and shop fabrication.

Durable Construction

The assembly comes complete with a heavy-duty ground clamp pre-attached to the cable. The clamp is designed with a strong spring mechanism and conductive contact points to bite through light rust or scale, ensuring a low-resistance path for the welding current. The welding cable itself is insulated with a durable jacket that resists abrasion, cuts, oil, and sparks, ensuring a long service life even in tough workshop conditions. Whether you are replacing a damaged lead or outfitting a new machine, the Tweco 9255-1140 provides the reliability professional welders demand.
