XL4015-35 - Tregaskiss TGX 400A MIG Gun, 15ft, .035 Wire, Miller Plug

Technical Precision and Durability

The Tregaskiss XL4015-35 TGX MIG Gun is an air-cooled, 400-amp welding torch engineered for professional GMAW applications. This model is specifically configured with a Miller-style back-end connection, making it a direct replacement or upgrade for compatible wire feeders. The gun is rated for 400 amps, providing ample thermal capacity for high-deposition welding on mild steel, stainless steel, and aluminum applications when equipped with the proper liner. The 15-foot cable assembly features high-quality copper stranding and a durable outer jacket designed to withstand the rigors of industrial environments, including exposure to spatter, oil, and physical abrasion.

At the front end, the TGX gun utilizes Tregaskiss's proprietary TGX consumables. These components are designed for optimal electrical conductivity and heat dissipation, ensuring stable arc characteristics and extended contact tip life. The gun comes pre-fitted for 0.035-inch (0.9 mm) wire, a standard diameter for a wide range of fabrication tasks. The gooseneck geometry is optimized to provide excellent joint access while maintaining smooth wire feeding, minimizing the risk of bird-nesting or erratic feeding issues.

The TGX chassis is built to handle lower amperage applications and shorter arc-on times compared to heavy-duty robotic guns, yet it retains the robust build quality Tregaskiss is known for. The simplified design allows for easy maintenance; liners can be changed quickly, and the modular construction means repairs can be performed on the shop floor without specialized tools. For welders who demand consistency and reliability, the XL4015-35 delivers a stable arc and comfortable handling, shift after shift.
