The new lighter XR-Aluma-Pro Gun 301568 reduces fatigue, improves output and is rugged to withstand industrial environments. You can be assured of heavy-duty construction with all internal components designed to provide long lasting performance and feeding precision. The 4000 or 5000 specific tension settings and the replaceable feed cable liner ensure the very best wire feeding performance and arc consistency. Parts cost and service time are reduced by allowing a simple means of removing and replacing the liner and not the complete feed cable. It offers versatility with threaded quick-change 360-degree rotatable head tubes that 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. Head tubes are FasTip and Bernard Centerfire compatible. The 3-3/4 turn potentiometer provides better resolution when selecting the right wire speed for the job. You get quick connection between the control cable and electrical components (trigger, motor, potentiometer). An isolated, common, knurled drive roll helps reduce wear, reducing downtime and cost. Easy access to the drive assembly and removable head tube reduces service time. The pressure release lever allows drive rolls to be held open for wire changeover. The XR-Aluma-Pro gun 301568 weighs only 2.5 lbs (1.1kg) with a 100% Duty Cycle at 300A. 70-900 ipm Wire Feed Speed. Accommodates .030 - 1/16" Aluminum Wire. Cable length 15 ft. This is the direct replacement for the Miller 300000.
