The MAGNUM®™ 450WC Water Cooled Gun is rated at 450 amperes 100% duty cycle using carbon dioxide
shielding gas and cooled with water at a flow rate of .58 gallons per minute (2.2 liters per minute). It is also rated
400 amperes 100% duty cycle with mixed argon shielding gases. There are several models of guns designed for
gas metal arc welding (GMAW) with .035-1/16 (.9mm-1.6mm) solid electrodes and gas shielded flux cored arc
welding (FCAW) with .045-5/64 (1.2 mm-2.0mm) cored electrodes. The gun tube angle is as shown in the table
below and the gun has a Fast-Mate™ wire feeder end connector. Two 10 ft. (3.5 M) guns with a 45 degree gun
tube angle are available for feeding .035-1/16 (.9mm-1.6mm) aluminum electrode. Optional liners are available
for feeding aluminum electrode with the 60 degree guns. See ACCESSORIES section for details.
