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 its 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
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 50 lbs and fits into a cabinet measuring 19 ¾” long by 7 ½” wide by

Invertig 221 DV January 17, 2014
Reviewer: Scott Evans from Simi Valley Ca.  
I have been using the Invertig 221 DV air cooled machine for a few months now. I have been using it only on 110V. It seems to have plenty of power for all my needs. The foot pedal is nice. I ordered mine with a flexy torch head. I really love it! The superflex hose is amazing. Makes the torch feel so light.
The machine has a lot of bells and whistles, but it's very easy to set up and adjust.
The fan at idle is so quiet I don't know the machine is on. When you get on the power you can hear the fan spool up. Once off the pedal it goes right back down to nothing.
I would buy again and I tell all my friends about it.
Thanks HTP!
