Product Description

Miller 907204001 Dynasty 350 TIGRunner TIG Welder measuring 43 1/8" X 23 1/8" X 43 3/4" features a Blue Lightning arc starter to provide consistent arc starts and to increase productivity.

Welder featuring independent AC amperage control allows independent setting of EP and EN amperages while extending tungsten performance. Welding machine features Hot Start adaptive control that provides positive arc starts without sticking. Welder features Blue Lightning arc starter to provide consistent arc starts and to increase productivity. It is compatible with wireless remote controls and eliminates clutter and cord tangles in the work area. It features extended AC balance that controls the amount of oxide cleaning that is essential for high quality welds on aluminum. AC frequency controls the width of the arc cone and the force of the arc. It provides smooth and precise arc for welding exotic materials. High-speed DC pulse reduces heat input and increases travel speeds. Welder featuring AC frequency control adds additional stability for stick welding. Welder featuring low OCV stick reduces open-circuit voltage to 5 - 10 VDC when power source is not in use. It has a input voltage hook-up in the range 208 V - 575 V and includes power source, 8' primary power cord, 2 dinse connectors, runner cart, coolmate 3.5, setup and operation DVD. It works with 1/3 phase input and uses 50/60 Hz frequency to perform AC TIG, air carbon arc, DC TIG, pulsed TIG, stick, TIG, cutting and gouging. It has an output range of 3 A - 350 A ideal for precision metal fabrication, heavy fabrication, aerospace, aluminum ship repair, anodized aluminum fabrication, pipe and tube fabrication.


  • Auto-Line - Allows for any input voltage hook-up (208 - 575 V) with no manual linking, providing convenience in any job setting
  • HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination
  • Superior Arc Performance- Smooth running 7018 or stiffer, more penetrating 6010
  • Fan-On-Demand operates only when needed - reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine
  • 120 V auxiliary power receptacle for cooling system or small tools
  • Programmable start parameters allow independent starting conditions based on process and memory selections (amperage, time, and polarity)
  • Extended balance control range (30-90% EN) allows precise cleaning control and prolonged tungsten life
  • Lift-Arc start provides TIG arc starting without the use of high frequency
  • Wind Tunnel Technology is an Internal air flow that protects electrical components and PC boards from dirt, dust, and debris, greatly improving reliability
  • Program memory features 9 independent program memories that maintain/save your parameters
  • Auto-Postflow calculates the length of postflow time based on the amperage setting. This eliminates the need to independently set the postflow time for different amperages. This feature preserves your tungsten and prevents porosity
  • TIGRunner packages feature a 3.5 gallon cooling system. The cart is equipped with cylinder-carrying capabilities, filler rod holder, foot pedal holder, torch, and cable holders. A pullout drawer provides additional storage for torch consumables and tools
