Additional Features

Features
XMT 350 MPa expands the process capability of the XMT Series, with built-in Pulsed MIG operation. MPa stands for MIG, Pulse, advanced arc control. The advanced arc control provides:

  • Improved pulsed MIG welding on aluminum
  • More control over the puddle and weld bead using SharpArc
  • More robust and stable arc at very low arc lengths
  • Reduces heat input
  • Welds on a wider range of material thicknesses

Sharp Arc on the XMT 350 MPa:

  • Can handle virtually any MIG welding job, including those hard-to-weld alloys like aluminum, found at power generation plants and shipbuilding facilities
  • A low setting gives a more fluid puddle and a flatter bead appearance
  • A high setting gives a less fluid puddle and a ropier bead appearance
  • Can be adjusted to help customize the arc for the type of shielding gas being used

Additional features

  • Auto-Line Power Management technology allows for any input voltage hook-up (208-575V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable input power
  • 350 amps of aluminum MIG welding output at 60% duty cycle enables improved deposition through using larger diameter electrodes common in construction applications
  • Available with Dinse or Tweco-style output connectors
  • Power factor of .95 enables smaller fuses/breakers and primary wiring. Primary amperage draw at rated output is 25% less than the competition
  • Exceptional electrical efficiency. At 400 amps, efficiency is 87.24%, this helps to reduce the utility bill or fuel supply required to weld
  • Inverter arc control technology provides greater puddle control for superior 6010 Stick electrode performance
  • Auto Remote Sense enables unit to automatically use remote control if connected to remote control receptacle
  • Reduced OCV operation - an internal dip switch enables reduced open-circuit voltage Stick welding capability. OCV is typically below 15 volts
  • Process selector switch reduces the number of control setup combinations without reducing any features
  • Large, dual digital meters are easy to view and presettable to ease setting weld output
  • Lightweight, aerospace-grade aluminum case offers protection with the benefit of reduced weight
  • Wind Tunnel Technology™ Internal air flow that protects electrical components and PC boards from dirt, dust, debris... greatly improving reliability
  • LVC Line Voltage Compensation Keeps output of the power source constant regardless of fluctuation in input power ± 10%
  • Fan-On-Demand Internal power source cooling system that only works when needed, keeping internal components cleaner
  • Adaptive Hot Start for Stick Automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion
  • Lift-Arc Simply touch the tungsten to the work piece and the arc is initiated instantly and automatically without the use of high frequency
  • Optional 115 VAC auxiliary power provides 10 amps of circuit-breaker-protected power for water circulators, etc
