Item Details

  • Miller™ SyncroWave™ 250 DX TIG Welder Machine measuring 46" X 28 1/2" X 40 1/2" features adjustable balance control to clean and remove oxides. Welder featuring Syncro Start™ selects soft, standard and hot TIG starts for welding based on application, lead lengths and tungsten size. Welder features dual inline high-frequency points that provide intense high frequency for arc starting and stabilization. Digital welding meters display amperage and voltage to view actual and preset values for greater accuracy and repeatability. Last procedure recall simplifies the changeover of syncrowave back and forth from aluminum TIG to stainless TIG to stick welding. Square wave output with AC balance control features adjustable penetration and cleaning action while increasing arc stability on aluminum alloys. Stick welding features adaptive Hot Start™ that provides good arc strikes without sticking. TIGRunner™ system with Coolmate3X cooler ensures flow of coolant and increases productivity. Tilted operator interface provides added convenience to welding experience. Arc timer/cycle counter records actual welding time and number of arc starts. Square wave technology improves your weld quality and makes TIG welding easier. Welder featuring AC square wave welding current automatically removes the layer of oxide for producing high quality welds. The Syncrowave compensates for power fluctuation without changing your welding parameters. Easy load dual cylinder rack minimizes cylinder lifting. It utilizes an input power of 230/460/575 V and works with 50/60 Hz single phase input to perform AC TIG, air carbon arc, DC TIG, pulsed TIG, stick, TIG, cutting and gouging. It includes running gear, integrated Cool mate3X cooler, 4 ga of coolant, RFCS-14 HD remote foot control, 25' Weld Craft™ WP20 water-cooled torch, AK4C torch accessory kit, 15' 1/0 work cable with clamp, style connection kit, 12' rubber gas hose, Smith HM2051A-580 regulator/flow meter and torch cable cover. It has an output range of 3 - 310 A ideal for precision metal fabrication, aerospace, automotive applications, ship building, maintenance, repair, light and heavy manufacturing.


  • Coolmate3X cooler option on TIGRunner features a 3-gallon cooling system, A flow indicator provides visual indication that the system is working, The Coolmate 3X is also equipped with an external filter to stop any foreign objects from entering the water-cooled torch cable for better flow and longer life
  • Syncrowave 250 DX TIGRunner Compete! Now includes EZ Load™ Cylinder Rack, 4 gallons of coolant, and a water-cooled torch kit
  • Syncro Start™ for customized arc starts allows the operator to choose from three different starting conditions to optimize the application according to tungsten diameter and material thickness
  • Square wave output with AC balance control features adjustable penetration and cleaning action while increasing arc stability on various aluminum alloys, and helps eliminate tungsten spitting and arc rectification
  • Dual digital meters allow for quick and easy viewing of actual and preset values of amperage and voltage
  • Last procedure recall automatically recalls the last procedure set-up when switching polarity
  • Built-in preflow/postflow provides 0. 2 - 5 seconds of preflow and 0 - 50 seconds of postflow
  • Built-in consumable storage located on the front panel allows the operator to store and readily access the needed consumables to be more productive
  • Fan-On-Demand™ operates only when needed - reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine
  • Lift-Arc™ start provides TIG arc starting without the use of high frequency
  • LVC™ Line Voltage Compensation
  • Keeps output of the power source constant regardless of fluctuation in input power 10%™
  • 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
