  • XR-Aluma-Pro and XR-Pistol guns work in conjunction with XR-Controls, XR-AlumaFeed or select Millermatic machines to provide the best solution for push-pull applications.
  • Threaded quick-change 360° rotatable head tubes are available in different bends and lengths for even those hard-to-reach welds. Over 30 different styles to fit your application and welder's preference.
  • Wire tension settings (except XR-Pistol). 4000 or 5000 specific tension settings ensure the very best wire feeding performance and arc consistency.
  • Heavy-duty construction. All internal components are designed to provide long lasting performance and feeding precision.
  • XR-Aluma-Pro: Robust professional-grade gun has the highest duty cycle rating in its class. Easy access to drive assembly and removable toolless head tube reduce service time, by allowing a simple means of changing drive rolls and head tube - or performing routine maintenance without disassembly of gun.
  • Processes - MIG (GMAW) with aluminum wire (capable of other wires with optional hardwire kits), Pulsed MIG (GMAW-P) with optional pulsing power source.
  • Suggested power sources: Millermatic 252, Millermatic 350P/350P Aluminum. These power sources require XR-AlumaFeed or XR-Control: Deltaweld Series, Invision MPa, AlumaPower MPa, XMT Series (except VS model), Trailblazer Seri.
  • Industrial products are suitable for applications that do not require high-volume production.
  • They typically have a 40 to 60% duty cycle and/or rated output of 300 amps or lower. Industrial products are an appropriate choice for professional welders.
