17642113 - Tweco No. 4 MIG Gun Power Cable Assembly, 15 ft

Technical Overview: Tweco 1764-2113 Power Cable Assembly

The Tweco 1764-2113 is a specialized power cable assembly designed specifically for the classic Tweco No. 4 MIG gun series. This component serves as the critical umbilical link between the wire feeder and the welding gun, transmitting high-amperage welding current, shielding gas, and the wire liner simultaneously. Engineered for industrial environments, the assembly features a coaxial design that optimizes flexibility while maintaining a consistent cross-sectional area for current transfer, rated up to 400 Amps.

Constructed with high-grade copper stranding, the power conductor ensures minimal voltage drop over the 15-foot (5-meter) length, which is essential for maintaining stable arc characteristics in heavy fabrication. The outer jacket is manufactured from a durable, abrasion-resistant synthetic rubber compound capable of withstanding the harsh conditions of a welding shop, including exposure to hot sparks, metal chips, and dragging over concrete floors. The internal geometry is precise, allowing for the smooth insertion of wire liners and unobstructed gas flow, which is critical for preventing porosity in the weld deposit.

This assembly comes pre-terminated with the specific crimped connections required for the Tweco No. 4 rear connector and gun handle, ensuring a secure mechanical and electrical bond. Regular inspection of this cable is recommended; compromising damage to the outer jacket or internal strands can lead to resistive heating and reduced welding performance.
