17202117 - Tweco No. 2 MIG Gun Cable Assembly 15ft 200A

Industrial Grade Replacement Cable Assembly

The Tweco 1720-2117 is a premium replacement Cablehoz assembly designed specifically for the Tweco No. 2 series of air-cooled MIG guns. This assembly serves as the critical lifeline between the wire feeder and the gun handle, integrating the welding power conductor, shielding gas hose, and trigger control wires into a single, robust coaxial unit. Engineered for industrial reliability, this 15-foot (4.6-meter) assembly is rated for 200 Amps at a 60% duty cycle, making it suitable for a wide range of medium-duty fabrication and repair applications.

The construction of the Cablehoz features high-grade copper stranding optimized for efficient current transfer, minimizing voltage drop even at the full 15-foot length. This ensures a stable arc and consistent weld bead profile. Surrounding the conductor is a specialized insulating layer that separates the power lead from the control wires and gas path, preventing electrical shorts and ensuring safety. The outer jacket is manufactured from a high-performance rubber compound that offers exceptional resistance to abrasion, hot sparks, oil, and common shop chemicals, significantly extending the service life of the assembly in harsh environments.

Maintenance and repair professionals choose the Tweco 1720-2117 for its precise fitment and ease of installation. As a genuine OEM part, it guarantees compatibility with standard Tweco No. 2 back-end connections and handle assemblies. Replacing a compromised cable assembly is essential for troubleshooting issues such as erratic wire feeding, porosity caused by gas leaks, or intermittent trigger response. This assembly restores the gun to factory-performance levels, ensuring operational efficiency and weld quality.

The flexibility of the Cablehoz is a key design feature, balancing durability with ergonomics. The assembly is rigid enough to prevent kinking—which can disrupt wire feeding—yet flexible enough to allow the welder to maneuver the gun into difficult positions without excessive wrist strain. This balance is achieved through Tweco's proprietary cable manufacturing process, which has set the standard in the welding industry for decades.
