Successful welding with aluminum requires a stable arc. With its short feed distance, this spool gun provides a steady, reliable feed of the soft aluminum wire. Canaweld Spool guns improve the “feed ability” of aluminum and other type of wires that are difficult to feed, through the standard MIG gun, by locating a small 1 lb. 1/ 4-inch diameter spool of wire on a pistol-grip style gun. CST251 spool gun is a 200 A lightweight, well balanced semi-automatic spool gun, with dual groove drive rolls, heavy duty and all metal wire feeder and is easy to set up. It has been designed for easy and reliable aluminum wire feeding with a variety of CV power sources and engine-driven welders. The control connector is metal-made too. It features easy access to the drive assembly which reduces service time and allows for routine maintenance without disassembly of gun.
