10501085 - Tweco Classic 5 MIG Gun, 500A, 15ft, Tweco Connection

Heavy-Duty Industrial MIG Welding Gun

The Tweco Classic No. 5 MIG Gun (1050-1085) is a premier air-cooled welding torch designed for high-amperage industrial applications. Renowned for its durability and performance, this gun is rated at 500 Amps at a 60% duty cycle when using CO2 shielding gas, making it capable of handling thick plate welding, structural steel fabrication, and heavy equipment repair. The unit comes equipped with a 15-foot (4.6 meter) cable assembly, providing the necessary reach for large workpieces while maintaining consistent wire feeding characteristics.

This specific model features a standard Tweco rear connection, ensuring seamless compatibility with a wide range of wire feeders and power sources that utilize the Tweco-style adapter. The gun is factory-configured for standard wire sizes (typically .035" to .045") but is versatile enough to run wire diameters up to 3/32" (2.4mm) with the appropriate liner and contact tip changes. The air-cooled design simplifies setup by removing the need for water coolers, hoses, and potential leak points, while the heavy-duty copper components ensure efficient heat dissipation during prolonged welding arcs.

Maintenance is straightforward with the Classic No. 5. It utilizes the widely available Tweco 15 Series consumables (nozzles, contact tips) and 54 Series gas diffusers, reducing inventory complexity and downtime. The metal-jacketed conductor tube and rugged cable outer sheath are engineered to withstand the harsh environments of shipyards, mines, and fabrication shops. Whether running solid MIG wire or Flux-Cored wire, the Tweco Classic No. 5 delivers the reliability professional welders demand.
