XMT 350/450 Series Heavy Industrial Applications Quick Specs Construction Shipbuilding Railroad Truck/Trailer Manufacturing Fabrication Repair Shops Rental Fleets Power Generation Plants MIG (GMAW)/Pulsed MIG (GMAW-P)* Stick (SMAW) TIG (GTAW) Flux-Cored (FCAW) Air Carbon Arc Cutting and Gouging (CAC-A) Issued July 2012 • Index No. DC/18.83 Multiprocess Welding Power Source Input Power 350: Requires 3- or 1-Phase Power, 450: Requires 3-Phase Power Rated Output *XMT 350 CC/CV and 450 CC/CV with required optional control; not available with XMT 350 VS model. XMT 350 VS Wind Tunnel Technology ™ protects electrical components and PC boards from contamination. Fan-On-Demand™ cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine. Lift-Arc™ allows TIG starting without the use of high-frequency. Starts the arc without contaminating the weld with tungsten. Adaptive Hot Start™ increases the output amperage at the start of a weld if necessary, eliminating electrode sticking. XMT 350 Model Only Auto-Line™ Power Management Technology allows for any input voltage hook-up (208 – 575 V) with no manual linking required, providing convenience in any job setting. Ideal solution for dirty or unreliable input power. (450 model is manual link.) Dinse- or Tweco-style weld disconnects provide high-quality weld cable connections. (450 model utilizes studs.) Inverter arc control technology provides greater puddle control for superior 6010 Stick electrode performance, and outstanding MIG weld performance. Line voltage compensation keeps welding output constant even if input power varies by +/-10 percent. Line voltage compensation further expands to an amazing +37/-59 percent when operating on 460 VAC. Process selector switch reduces the number of control setup combinations without reducing any features. Large, dual digital meters are easy to view and are presettable to ease setting weld output. Lightweight, aerospace-grade aluminum case offers protection with the benefit of reduced weight. Power source is warranted for 3 years, parts and labor. Original main power rectified parts are warranted for 5 years. Gun warranted for 90 days, parts and labor.
