OVERVIEW

Reliable Miller-Compatible MIG Gun Solution

Upgrade your welding setup with the Tweco WeldSkill 400 Amp MIG Gun, featuring a 25-foot cable and a Miller-style rear connection. Identified by SKU 1047-1019, this MIG gun is part of the renowned WeldSkill family, which combines professional-grade features with exceptional value. It is specifically designed to replace OEM guns on Miller welding machines, offering a seamless transition for operators accustomed to high-performance equipment. The 25-foot lead length is a significant advantage for welders working in large bays or around expansive workpieces, reducing the need to constantly reposition the heavy power source.

Built for the Industrial Grind
The WeldSkill 400 is built to handle the rigors of daily industrial use. It boasts a 400-amp rating at a 60% duty cycle (with CO2), making it suitable for medium to heavy fabrication tasks. The air-cooled design is efficient and simple to maintain, eliminating the complexity of water-cooled systems while still providing substantial amperage capacity. The gun features a durable outer jacket that resists cuts, abrasion, and burns, ensuring the cable assembly survives the tough environment of a welding shop floor.

Superior Ergonomics and Consumables
Welding fatigue can significantly impact productivity, which is why the WeldSkill 400 features an ergonomic handle design. The balanced weight distribution and comfortable grip allow for precise torch manipulation with less strain on the wrist and forearm. Furthermore, this gun utilizes the legendary Tweco consumable platform. By using standard Tweco contact tips, gas diffusers, and nozzles, you benefit from a supply chain that is vast and reliable. The simplified front-end design allows for quick consumable changes, keeping your arc on time high.
