91101177 - Thermal Arc 250A Stick Electrode Lead Assembly with 50mm Dinse

Product Overview

The Thermal Arc 91101177 is a complete Stick (SMAW) welding lead assembly designed to meet the rigorous demands of industrial welding environments. This assembly is rated for a maximum output of 250 Amperes, making it suitable for a wide range of medium-to-heavy duty welding applications. The unit comes pre-assembled with a high-quality electrode holder, a durable welding cable, and a machine-side connector, facilitating immediate deployment and reducing downtime associated with component assembly.

Technical Specifications

The core of this assembly is the 13-foot (approximately 4 meters) welding cable. The cable length is optimized to provide sufficient reach for the operator while minimizing voltage drop, ensuring consistent arc characteristics at the workpiece. The cable is terminated on the machine end with a 50mm Dinse (50D) connector. This large-style Dinse connector provides a secure, twist-lock electrical connection that maximizes surface contact area to prevent overheating at the terminal point. It is compatible with any power source equipped with standard 50mm Dinse output receptacles.

Construction and Compatibility

The electrode holder included in this package is designed for ergonomic handling and secure electrode retention. It features heavy-duty jaw springs and high-conductivity copper alloy contact points to ensure efficient current transfer to the welding rod. The cable insulation is formulated to resist common workshop hazards, including abrasion, oil, and sparks. This specific part number is an OEM replacement for Thermal Arc welding machines but is universally compatible with other power sources requiring a 250A rated lead with a 50mm Dinse connection.

Application

Ideal for maintenance, repair, and fabrication shops, this lead assembly supports the Shielded Metal Arc Welding (SMAW) process. It is capable of handling various electrode diameters consistent with a 250A output range. Users should verify their machine's output terminal size (Dinse 25 vs Dinse 50) prior to procurement to ensure proper fitment.
