OVERVIEW

Heavy-Duty Replacement Cable for Tweco MIG Guns

Keep your welding operations running smoothly with the Tweco Hefty Cable Assembly (870194). Designed as a direct replacement for compatible Tweco MIG guns, this assembly restores the electrical and mechanical integrity of your welding torch. Over time, cable assemblies can suffer from internal strand breakage, liner compression, or outer jacket damage, all of which lead to poor wire feeding, erratic arcs, and overheating. Installing a genuine Tweco Hefty assembly resolves these issues, returning your equipment to factory specifications.

The "Hefty" designation refers to Tweco's commitment to durability. The outer sheath is constructed from a high-grade rubber compound that resists the harsh realities of metal fabrication, including exposure to hot sparks, sharp metal edges, and heavy equipment traffic. Inside, the assembly houses the power conductor, gas line, and control wires in a configuration that promotes longevity and safety. The copper cross-section is sized to handle the amperage requirements of industrial welding without excessive heating, ensuring operator comfort and equipment safety.

Installation is straightforward for maintenance personnel familiar with Tweco guns. The assembly is designed to mate perfectly with the rear connection of the gun handle and the machine-side pin or adapter. By choosing a genuine Tweco replacement part, you ensure that the gas seals, electrical connections, and liner conduits align perfectly, preventing leaks and feed issues. Invest in the longevity of your welding torch with this high-performance cable assembly.

FAQ

The assembly typically includes the main power cable, the outer protective jacket, the internal gas hose, and the control wires for the trigger. It is a complete conduit connecting the gun handle to the machine plug.

Signs include the cable becoming extremely hot during use (indicating broken strands), visible cuts or burns on the jacket exposing internal wires, or persistent wire feeding issues that changing the liner doesn't fix.

No, it is specific to certain models and amperage ratings. Please verify your MIG gun model (e.g., Spray Master, Classic) and the required length before purchasing.

Typically, cable assemblies do not include the wire liner. The liner is a separate consumable that is inserted into the cable assembly and must be matched to your wire diameter.

The 'Hefty' line features a thicker, more durable outer jacket designed to resist abrasion, cuts, and heat better than standard lightweight cables, making it ideal for industrial environments.

Minor cuts can sometimes be taped, but if the internal copper strands or gas hose are compromised, the entire assembly should be replaced to prevent safety hazards and gas leaks.
