10401147 - Tweco No. 4 MIG Gun 400A 15ft Lincoln Connection

Heavy-Duty Industrial Welding Performance

The Tweco No. 4 Air Cooled MIG Gun is a legendary tool in the welding industry, renowned for its rugged durability and consistent performance in demanding environments. Designed to handle up to 400 Amps, this MIG gun is the go-to choice for fabricators and welders who require a reliable torch for heavy structural steel, manufacturing, and general fabrication tasks. The model 1040-1147 is specifically configured to meet the needs of professionals using Lincoln Electric wire feeders, featuring a direct Lincoln-style rear connection that eliminates the need for adapters and ensures a secure, conductive fit.

One of the standout features of this assembly is its 15-foot cable length. This extended reach allows welders to move freely around large workpieces and fixtures without constantly repositioning the wire feeder. The cable itself is built to withstand the rigors of the shop floor, resisting cuts, abrasion, and heat. Being an air-cooled unit, it offers the significant advantage of simplicity; there are no water lines to leak or coolant levels to monitor, making it an excellent choice for field work and shops where portability and low maintenance are priorities.

This specific configuration comes ready to weld with 1/16-inch wire, a diameter often chosen for high-deposition rates on thick materials. The gun utilizes standard Tweco consumables, which are widely available and easy to replace, ensuring that downtime is kept to a minimum. The ergonomic handle is designed to fit comfortably in the hand, reducing operator fatigue during long welding sessions. Whether you are welding in a shipyard, a heavy equipment repair facility, or a structural steel plant, the Tweco No. 4 delivers the arc stability and wire feeding performance necessary for high-quality welds.

Investing in a genuine Tweco No. 4 means investing in longevity. The gun's components are engineered for easy serviceability, allowing users to replace liners, contact tips, and nozzles quickly. With its robust design and high amperage rating, this MIG gun stands as a testament to Tweco's commitment to quality and the welder's productivity.
