250A TIG output on 240V power drives deep penetration on aluminum and steel without oversized shop machines.
150A TIG output on standard 120V circuits keeps repair jobs moving where only wall outlets exist.
AC/DC Mix TIG blends oxide cleaning and penetration in one arc for faster heavy aluminum weld passes.
0.4–1000 PPS pulse control stabilizes puddle heat on thin metals while producing consistent stacked-bead appearance.
54 lb machine weight moves easily between shop bays, trailers, and job sites without hauling bulky welders.

HTP Independence 251 Dual Voltage AC DC TIG Welder Machine Only Miller Compatible Package Product # tig251dv-miller
*This package will only work if you already own a Miller® Tig torch with the 35 dinse and the Miller®14 pin foot pedal.
Includes: Independence 251 DV welding machine, dual voltage adapter cord, two 5/8-18 RH to 1/4 BSP gas fitting adapters Does Not Include: Flowmeter, gas hose, TIG torch, ground cable, foot pedal, welding cart, gas bottle, tungsten, filler rod
Dual voltage AC DC TIG welder designed for welders who already own compatible Miller TIG accessories.
This package includes the Independence 251 dual voltage welding machine configured for users who already own Miller compatible TIG equipment. It allows the operator to reuse a Miller TIG torch, ground clamp, 14 pin foot pedal, gas hose, and flowmeter.
The machine supports TIG welding, pulsed TIG, Stick welding, and carbon arc gouging. It operates on either 120V or 240V input power and delivers up to 250 amps of TIG output when connected to 240V power.
This configuration is intended for welders who want the Independence 251 power source while continuing to use existing Miller accessories. The machine requires a 35 Dinse TIG torch connection with a side gas connection. Flow through torches require a different connection.
Input Voltage: Dual voltage 120V or 240V Maximum TIG Output: 250A Maximum Stick Output: 200A AC Frequency Range: 20 to 400 Hz under 100A AC Frequency Range: 20 to 200 Hz above 100A AC Balance Range: 10 to 90 percent Programmable Memory Slots: 8
USED FOR • Aluminum TIG welding and fabrication • Welders upgrading from Miller equipment • Motorsports and fabrication shops • Shops needing dual voltage TIG capability
Not For • Users without compatible Miller TIG accessories • Shops without 120V or 240V power • Users needing a complete ready to weld package
