Product Description

Miller 951117 Syncrowave 250 DX TIG Welder Machine 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. It features pulsed TIG control that lowers heat input into the part and reduces warping as well as distortion. 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 Coolmate 3X 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 208/230/460 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 mate 3X 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.
