Tweco, an ESAB brand, has introduced the Fusion Pro 450, a water-cooled MIG gun designed for running wires from .035- to 1/16-in. diameter in medium- to heavy-duty industrial fabrication, maintenance and repair applications. Using mixed gas, the Fusion Pro 450 is rated at 450 amps at 100 percent duty cycle; with CO2 shielding gas, it is rated at 500 amps at 100 percent duty cycle.
“The robust Fusion Pro 450 offers an ergonomic and well-balanced handle with rubber soft areas and a ball-and-socket connection with spring support between the handle and the cable to reduce strain and make it easier for the operator to manipulate the gun,” says Jeff Henderson, Global Business Manager for Torches, ESAB. “Both features are new to the Tweco line. Coupled with its high heat dissipation capabilities, the Fusion Pro 450 enhances operator comfort in high arc-on time, high duty cycle applications, such as spray transfer, pulsed MIG and Flux-Cored welding with larger wires.”
The Fusion Pro 450 uses easy-to-service front-end consumables, similar to those found on the Tweco Supra 450 water-cooled MIG gun, but it also features an insulated torch neck and slip-on nozzle that makes the torch more comfortable to handle. Guns come with 10- or 15-ft. cables and are available with standard Tweco back-end connections, Euro-style connections or connects for other leading wire feeder brands.
For higher amperage needs or running 3/32-in. diameter wires, Tweco offers its Standard 600-amp water-cooled MIG gun, which has a 100 percent duty cycle at 600 amps with CO2 shielding gas.
