Temporarily out of stock; new inventory expected mid-December.

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 its 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 dont even offer at twice the price! Its 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 221s 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 isnt a job out there the 221 cant handle.

Lets face it, control of the arc is the foundation of better welds and precision results. With the 221s 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" long by 7-1/2" wide by 15-3/4" high. The Invertig 221 package includes the Invertig 221 power source, a 12-1/2' 17-Series air-cooled TIG torch, a 12-1/2' foot pedal, a 10' ground cable and clamp assembly, and a flowmeter. Welding cart 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 dont like it we will take it back, no questions asked. Further, we back the machine with a 3-year warranty.

HTP Invertig 221's Arc Blows Miller Dyansty Away October 27, 2018
Reviewer: Jason Quinlan from Coventry, RI United States  
I own both the HTP Invertig 221 and The Miller Dynasty 210DX and i have to say this Invertig's arc is so smooth and buttery i dont use my Miller much it sits in the corner staring at my Dynasty envious its being used. The HTP has a few features the Dynasty does not like AC Amplitude which is way better than the gimmick of wave forms. HTP also has 10-99% Balance miller is 50-90% so you get more rang. The HTP will also pulse stick weld while the Miller doesn't. Do your self a favor and get the HTP Invertig 221 and gte the 10 more amps and the better arc. This machine has never let me down. When you order this you will get the CK torches and SSC pedals unlike Everlast where you don't get premium accessories. This machine has been out for almost 10 years its time tested. You wont find a bad thing about this machine. The service is the best you'll ever find as well....You will not regret getting this machine. I love mine and i know you will too.

Invertig 221 - This Thing Oozes Quality May 22, 2017
Reviewer: WD from Virginia  
The features that sold me were: 220amps, good duty cycle, full feature set, reputation for quality design, build, & customer service, top quality peripherals (foot pedal, torch, flow meter & ground clamp).

After using the machine for several projects, I’m utilizing features that I never thought I needed:

Digital Display for everything – this is so much better than a simple knob
Spot Timer - awesome for fusion tacks (like Jody)
Low current starts
Adjustable post flow - Argon is lasting forever
Full set of pulse tools – frequency, duration & background all controlled with a digital numeric display
On demand fan – I’ll never have another welder w/o this feature

It really is a joy to use.  The quality, precision, adjustability and smoothness has exceeded my expectations.  If you’re looking for an inexpensive hobby machine, buy a Chinese import.  If you’re looking for a professional level machine, that’s going to be rock-solid reliable, stretch you budget and get the HTP.

Awesome machine!! November 30, 2016
Reviewer: leslie thibodaux from Schriever, LA United States  
Did my first job with the 221 and I have to say this machine welds like a champ!! Welding on .100 thick 5052 plate. Corner joints and T-joints. AC balance at 75 and 100Hrz and 125 amps, this thing lays down a beautiful weld even with 2%thoriated tungsten. Well worth the money and couldn't ask for a better machine!! Thank you USA Weld for the fast shipping and a wonderful product!!!

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..
;-)
