The Tweco 10401133 is a premium replacement MIG gun designed for professional welders who demand reliability and performance. This model is a genuine Tweco No. 4 air-cooled gun, factory-fitted with a Miller-style back-end plug. This configuration allows for immediate plug-and-play compatibility with most industrial Miller wire feeders and integrated MIG machines, upgrading your setup with the proven durability of the Tweco platform.
Performance Specifications:
At the heart of this gun is its impressive 400-amp rating (at 60% duty cycle using CO2 gas). This high amperage capacity makes it suitable for running large diameter wires, including flux-cored and solid wires up to 5/64" (2.0mm), although it is commonly set up for .035" to .045" wire in general fabrication. The air-cooled design eliminates the complexity of water coolers, making it a rugged choice for field work, shipyards, and heavy equipment repair.
Construction and Durability:
Tweco guns are renowned for their serviceability. The 12-foot cable assembly features a heavy-duty copper stranding configuration that maximizes current transfer while maintaining flexibility. The outer jacket is engineered to resist oil, ozone, and physical damage. Unlike disposable guns, the Tweco No. 4 is fully repairable; from the trigger switch to the conductor tube, every component can be replaced, extending the lifespan of the tool significantly.
Consumable Compatibility:
This gun minimizes inventory headaches by using standard Tweco consumables. It accepts:
For welders who prefer the specific feel and balance of a Tweco torch but operate a Miller fleet, the 10401133 is the ideal solution. It bridges the gap between equipment brands, delivering the best of both worlds: Miller power source reliability and Tweco gun performance.
