Description
 
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.



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

15 ¾" high. The Invertig 221 package includes a 12 ½' long 17-Series air-cooled TIG torch, 12 ½’

long foot pedal, 10' ground cable clamp, flowmeter and 70 minute TIG DVD.


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 questions asked. Further, we back the machine

with a 3-year warranty. Welding cart not included.

HTP Invertig 221 April 27, 2016
Reviewer: Wayne Hopfe from Bakersfield, CA  
I love welding since I bought this machine. I had never been happy with my welding on the old Lincoln AC225 or even a Century 130 wire feeder. This machine has solved all those issues. I no longer grind anything to make it look good and I have easily welded aluminum from .050 up to more than 3/8". I tigged up a 24 gauge VW bug fender for a friend of mine, running 15-17 amps. It came out very nicely. I love this machine!

LOVE IT! December 19, 2015
Reviewer: Jason A from Texas  
After spending years doing MIG work in my home garage, I found myself needing to learn how to TIG.  I've owned this machine only a short time and while I'm still not the tig master, I am finding this machine is helping me progress my skills very quickly.  The HF start makes life super easy for a novice like me.  I shopped for months and ALMOST fell for the green machines from China.  I'm glad I discovered HTP and their Italian company Stel.  If the HTP machine was blue, you'd have to spend over 5k for the same features and still not get duty cycles like this inverter welder!!!  USAWELD, has been great to work with so far and the accessories like the ground clamp, regulator and CK torch are top notch quality.  What do they say?  Drive a lincoln, drink a miller and weld with an HTP?  Works for me!  Sure wish I got a T-shirt with my welder..
;-)

Amazing unit November 21, 2014
Reviewer: Andrew from Spokane, WA  
I've had this machine since about March of 2014, and tackled many jobs big and small with it. From Titanium pie cuts to 1 inch thick aluminum. Its got so much versatility, from the small size to wide range of settings. I'm very picky when it comes to quality of the machine its self, and i could not find one thing i didnt like, even when i took it appart, it's built solid and will last for a years to come. If you're on the border about getting a dynasty or inverting 221, what really sold me was Customer service. I've called 5 times and always talked to the same person. try to get that with miller. They will bend over backwards to make you happy and care that you're happy with there product. It's a fantastic unit in every way!

Superb machine May 13, 2014
Reviewer: Anonymous Person from Little Rock, AR.  
I researched this machine for three days before purchasing it, TRYING to find some negative comments on it,...I found absolutely none!!!  I bought a Chinese made TIG last year, and it was almost like a toy compared to this machine.  When I have visitors to my shop, I show them a side by side comparison on the differences of this machine to the Chinese made ones,...things as simple as a ground clamp, are just worlds apart in quality.  I've never seen such a well built machine for this price.  The hose to the torch is unbelievably flexible and easy to work with.  I'm a beginner TIG welder and from the very first arc that I fired up, I was laying beautiful beads.  I can't say that for my Chinese version.  The foot pedal is heavy and wide, and is so proportionally controllable,...I love it.  There are very few things that I have ever purchased that were worth every penny spent on it, like this welder.  If you're shopping for a great TIG welder, you can stop looking and buy the HTP 221.
