The Magnum 450WC is a water cooled gun and cable assembly designed for both
To function properly, the 450WC must be connected to a water cooler. Water flows through the gun cables and han- dle to the end of the gun tube, cooling the gas diffuser and nozzle.
In addition to keeping the contact tip cool, the outgoing end of the gun tube is specially designed for maximum heat transfer between the cooling water and the gas nozzle. The gas nozzle will not overheat, even when operating the gun at 100% duty cycle.
This results in cool operation in appli- cations such as spray transfer, pulse welding and when using argon blended gas.
The gun has two ratings when cooled at a minimum water flow rate of .58 gallons (2.2 liters) per minute.
With straight CO2 gas:
450 amps, 100% duty cycle.
With argon/CO2 blended gas: 400 amps, 100% duty cycle.
The wire diameter range is
.035 - 5/64” (0.9 - 2.0mm):
Solid Wire:
.035 - 1/16” (0.9 - 1.6mm)
.045 - 5/64” (1.2 - 2.0mm)
