10501113 - Tweco Classic No. 5 MIG Gun 500A 15ft 1/16 Wire

Heavy-Duty Industrial Performance

The Tweco No. 5 Air Cooled MIG Gun (Part Number 1050-1113) represents the pinnacle of air-cooled welding technology for heavy industrial applications. Designed to handle high amperage outputs without the complexity of water-cooling systems, this gun is rated for 500 Amps, making it suitable for structural steel, heavy equipment manufacturing, and demanding fabrication environments. The unit comes fully assembled with a 15-foot cable, providing significant reach for welders working on large assemblies or in situations where the wire feeder cannot be positioned immediately next to the workpiece.

Optimized for Heavy Wire

This specific configuration is set up for 1/16-inch (1.6mm) welding wire, a standard size for high-deposition welding. The internal liner, contact tip, and gas diffuser are engineered to ensure smooth wire feeding and consistent electrical conductivity, which are critical for maintaining stable arcs at high currents. The air-cooled design utilizes heavy-duty copper components and high-temperature insulation materials to dissipate heat effectively, ensuring the gun remains operational during extended welding cycles. The robust construction minimizes downtime associated with overheating, a common issue in lesser-rated air-cooled guns attempting to push high amperages.

Classic Design and Compatibility

Part of the renowned "Classic" series, the No. 5 gun features the signature Tweco handle design that has been an industry standard for decades. The connection style is the standard Tweco rear connection, ensuring compatibility with a vast array of wire feeders and power sources found in industrial settings globally. Maintenance personnel appreciate the modular design, which allows for rapid replacement of consumables and trigger components. The cable assembly is reinforced with durable outer jacketing to resist cuts, burns, and abrasion common in harsh shop environments. This product delivers a reliable GMAW solution that balances power, durability, and ease of integration.
