The
Invertig 221 AC/DC Inverter TIG welder will allow you to produce welds with all types of metal! We increased the maximum welding current by 10% to a full 220 amps of rugged welding power. And we put the machine on a diet, the HTP Invertig 221 weighs in at only 40 lbs, so it’s easy to take right to the job! We also added the Invertig 221 DV (Dual Voltage) which welds on both 110 volts and 220 volts – the ultimate in portability.


The Invertig 221 is packed with features many of our competitors don't even offer at twice the price! It's the only welder in it's class with independent AC amperage adjustment. This feature gives you precise control over the heat input to both the workpiece and the tungsten by allowing you to separately adjust the electrode negative and electrode positive amperage.



Welding cart NOT included; Includes CK Worldwide 20 Series TIG torch with zippered Nylon cable cover.
Conventional transformer TIG welders have a fixed AC frequency of 60 Hz (same as your household current).
They use a pure tungsten electrode which forms a ball when welding AC. The Invertig 221 offers you the
ability to adjust the AC frequency from 20 Hz to 200 Hz – the higher AC frequency gives you a more focused
arc with greater arc control. With an inverter, running a higher AC frequency, say in the 150 Hz to 200 Hz
range allows you to use ceriated, lanthanated, or thoriated tungsten sharpened to a point. Which:
TIG Welder Invertig 221 top view • Allows the arc to jump from a point instead of
a ball, which provides unparalleled arc stability
and reduces "arc wandering".
• Produces a more focused arc, resulting in a
narrower bead and making it much easier to
weld inside corners.
• Minimizes the heat affected zone as the heat
is more concentrated, making it easier for both
the novice and professional to weld thin materials.

The 221 also gives you precise control over the
AC balance (from 10% to 90%) so you can
control the arc cleaning action.



The 221 is also an excellent DC welder too. The smooth, stable arc coupled with the 221’s high speed pulse DC pulse make intricate work on mild steel, 4130, stainless, inconel and titanium a breeze. High speed DC pulse focuses the DC arc much like the AC balance focuses the AC Arc – the end result – more control and less arc wandering. With a pulse rate of up to 999pps, there isn’t a job out there the 221 can’t handle.

Let’s face it, control of the arc is the foundation of better welds and precision results. With the 221’s independent AC amperage adjustment, adjustable AC frequency, adjustable AC balance, and high speed DC pulse, the 221 gives you arc control like you never before experienced.

The 221 allows you to store up to 64 separate welding programs. So, say you found a setting you really like for welding aluminum radiator tanks to cores. AC – On, HF – On, Max Current = 180 amps, AC Balance = 65%, AC Frequency = 180 Hz, EP = 60%, Pulse Freq 1 Hz, Peak Time 80%, Background Current 30%. Simply store this program and you can come back to it when you have another tank to core job. Assigning banks of memory slots to multiple welders allows them to access their personal settings in a job shop environment.

Our Dual Voltage model can be ordered with or without a water-cooler.

Conventional arc welding is really simple with the Invertig 221. Using the stick mode in conjunction with the foot pedal, allows you to vary the welding amperage. Perfect when doing pipe welding!

Select the touch start mode for welding aluminum or any other material without High Frequency. This is important if your application takes you near sensitive electronic equipment, such as on site repairs in a hospital or repairing aluminum vehicles with on-board computers.

This package of power weighs just 48 Lbs. and fits into a cabinet measuring 19-3/4" L x 7-1/2" W x 15-3/4" H. The Invertig 221 package includes the Invertig 221 DV power source, a 12-1/2' 20 Series water-cooled TIG torch with a zippered Nylon cable cover, a 12-1/2' foot pedal, the Arctic Chill water-cooler, a 10' ground cable and clamp assembly, a flowmeter, and 2-gallons of coolant. The welding cart is NOT included.

The advanced technology found in the Invertig 221 will allow you to produce professional quality welds in all types of metal – quickly, easily and affordably. And every Invertig 221 comes with our 90-Day Money-Back Guarantee. We are so sure you will love your Invertig 221 that you can try it in your own shop for 90-days – if for any reason you don’t like it we will take it back, no questionsa asked. Further, we back the machine with a 3-year warranty.

Invertig 221 water cooled dual voltage review June 11, 2015
Reviewer: RJB from Reno, Nevada  
I intentionally waited before writing this review.  I have used it almost every day since late 2014.  I am retired and not a professional welder but I love to weld for relaxation.  I can honestly say I love this welder.  

I have used other high end inverter TIG welders as well and for the price, the extensive range, multiple settings, it is fabulous.  At very low amperages the arc is extremely stable and I have never overrun the duty cycle at high settings.

What sets this welder apart from anything in its class is the ability to control amplitude in AC and control the bead when welding aluminum.  

I didn't buy it as a stick welder but it works well on everything from 6010, to 7018, to 7024.

HTP Customer service is the gold standard.  It is reassuring that there are internet businesses, where the consumer can get immediate resolution to any issue.

I am not paid and have no link to the company other than being an extremely satisfied customer.
