The Tweco Fusion 250 MIG Gun (1023-1069) is a premium air-cooled welding gun designed for medium-duty industrial applications. Engineered to be a direct replacement for Miller-style wire feeders, this unit features a robust 250-amp rating at a 60% duty cycle, making it suitable for a wide range of fabrication tasks involving mild steel, stainless steel, and aluminum.
This model comes equipped with a 15-foot (4.6 meter) cable, providing ample reach for working around large assemblies. The backend connection is specifically configured for Miller power sources, ensuring a plug-and-play installation without the need for adapters. The gun is factory-setup to run 0.035" to 0.045" (0.9mm - 1.2mm) welding wire, utilizing a high-quality steel liner that promotes consistent wire feeding and minimizes bird-nesting.
A defining feature of the Fusion series is the integration of Velocity consumables. Unlike traditional threaded contact tips, Velocity tips feature a threadless, drop-in design that seats firmly into the gas diffuser. This design maximizes surface contact for superior electrical conductivity and heat dissipation, resulting in a more stable arc and longer consumable life. The nozzle also utilizes a secure seating mechanism that prevents it from loosening during operation.
The gun assembly is built to withstand harsh industrial environments. It features a rugged outer jacket that resists cuts and abrasion, while the handle is molded from high-impact polymer. Heavy-duty strain reliefs at both the gun handle and the machine connection point protect the internal cabling from kinking and stress damage, ensuring long-term reliability.
