The Prince XL and Magnum SG are spool guns that can add wire feeding capabilities for aluminum and stainless with a variety of constant voltage power sources and engine driven welders. The Prince XL provides performance for aluminum applications. It is rated at 200 A at 100 percent duty cycle. It is capable of feeding 0.030 in. to 1 /16 in. diameter wire on up to 4 in. diameter spools at speeds up to 900 IPM. Featuring a 3 3 /4-turn wire feed speed potentiometer control for precise fine adjustment of wire speed, it is offered with a 25 ft. cable length and comes standard with a leather cable jacket cover with Velcro closure. Available with the standard straight barrel or the optional curved barrel to assist in hard-to-reach settings, the EZ-Lock barrel design makes changing or rotating the barrel an easy, no-tool twist of the wrist. The braking system eliminates the need to adjust and re-adjust braking tension. A wire paddle, which maintains slight pressure, keeps the wire flat on the spool to reduce wire tangling and unraveling. The Magnum SG is a low-cost, lightweight, hand-held semiautomatic spool gun designed for aluminum welding. The model features a variable speed control adjustment at the gun eliminating the need to walk back to the power source. It is rated at 250 A at 60 percent duty cycle. It is capable of feeding from 0.023 in. to 3 /64 in. wire diameters on up to a 4 in. diameter spool at speeds up to 650 IPM. The gun includes a 25 ft. cable to allow extra reach away from the power source. See through spool and body covers enable the user to see wire supply and check wire feeding for ensured performance.
