This package is for customers who want the brand new HTP® Independence 251 DV welder but would like to use their existing Miller® accessories -torch, ground clamp, foot pedal (14pin) and existing gas hose and flowmeter (please note that your Miller TIG torch will need the 35 Dinse connection with the side gas connection, if your torch is flow thru you will need a new dinse connection).  When you order this package in the dual voltage option you get the Independence 251DV welder, two adapters to convert the 5/8-18 gas fittings to 1/4BSP, and the 110/220 adapter cord.  

Power Forged in Independence. 

From the sparks of revolution to the spirit of American craftsmanship, HTP America brings you the Independence 251 AC/DC — a TIG machine that delivers unmatched performance with the grit and reliability American welders demand. 

If the INDEPENDENCE 210 AC/DC was the declaration, then the INDEPENDENCE 251 AC/DC is the Constitution — the solid foundation of TIG power, control, and versatility that lets you weld without limits. 

Built on the legacy of the Invertig 251 AC/DC, the Independence 251 AC/DC keeps everything you loved — and flies it under a new banner. Designed for those who take pride in their work and stand tall behind every weld they make.

This machine is your TIG torch of liberty. 

This is not just another TIG welder — it’s a symbol of what happens when rules are broken and welders not “bean counters” build elite welding machines. 

🔥 FEATURES OF THE INDEPENDENCE 251 AC/DC

⚡ 250 Amps of TIG Power – AC & DC Modes 

Confidently weld everything from aluminum to stainless, mild steel, titanium, and more — with smooth, stable arc control throughout the full range.

🔄 AC/DC Mix TIG Mode 

Combine the cleaning power of AC with the deep penetration of DC in a single arc. Perfect for heavy aluminum and high-speed productivity — ideal for structural, motorsports, and marine applications. 3 AC wave forms to choose from and mix wave shapes. 

🔁 Double Pulse TIG 

Add rhythm and control to your welds. Reduce heat input, minimize warping, and create that signature “stacked dime” appearance with ease — even on tricky metals and thin gauge material. The perfect tool for titanium.

⚙️ Fast Tack Function 

High-frequency, low-distortion arc starts for quick tacking without filler — ideal for precise fixturing and fit-up work where every second counts. 

🎯 Full AC Frequency & Balance Control 

Dial in the exact arc shape, focus, and cleaning action for your job. Whether you’re welding cast, extruded, or mirror-finish aluminum — you’re in control.

⏱️ Start & End Amps with Adjustable Slopes 

Soft starts and smooth finishes — set your arc exactly how you want it to begin and end, from razor-thin sheet to thick section fabrication.

🧠 Memory Function & Preset Jobs 

Save and recall your favorite settings in seconds — fast setup for repeatable jobs in the shop or field. 

🔥 Carbon air arc gouging  

Easily remove old welds, cut castings, remove stainless and leave a surface ready to just touch up with a grinder or in most cases to weld to right away. 

🖥️ Large Color Display & Intuitive Controls 

Big, bright interface with simplified menus. Quickly adjust key parameters without digging through layers of complexity.

🌀 Fan-On-Demand Cooling 

Runs quiet when idle. Powers up when things get hot — keeps your machine clean and efficient.

🧰 AC and DC Stick Welding Mode with Pulse 

Versatile enough for maintenance and structural welding with stick. Quick polarity changeover and smooth arc response. 

🔌 Dual Voltage – 120V & 240V Compatible

Take it anywhere. Plug into standard 120V power for light-duty jobs or go full throttle at 240V for high-output TIG work. 

🪶 Portable Powerhouse – Under 60 lbs 

Easily moves between shop bays, race trailers, or job sites. Heavy-duty handle and compact form make it truly portable.

Steven W. ★★★★★

The dual voltage switch is a lifesaver for my shop and home setup, and it fired up perfectly with my old 14-pin foot pedal right out of the box. Took a bit to find the right settings, but the arc stability on 110V honestly surprised me.

Ryan ★★★★★

Finally a machine that runs smooth on both 110 and 220 without any hassle. The arc starts clean and stable right out of the box, even with my old Miller torch connected.

David ★★★★★

The dual voltage is a lifesaver—I plugged it into a regular 110 outlet at my buddy’s garage and it ran my 14-pin foot pedal without a hiccup. Swapping over my old Miller torch took five minutes, and the arc starts up clean every time.
