You have to see it to believe it! A combination 
TIG/stick welder delivering an impressive 130 amps of 
high performance DC TIG welding power, packaged in 
a compact, 11 lb., go-anywhere cabinet. It’s the HTP 
Invertig 131 DC/HF, and you’ll be happy to know that 
its affordable price tag is equally hard to believe.
Sounds good so far, but can the 131 DC/HF handle the 
wide range of jobs you might run into? No sweat! Able to 
weld up to  ” steel, this little workhorse is the ultimate 
machine for chrome moly roll cage fabrication in drag 
race cars, custom motorcycle tanks, fenders and frames, 
air frame fabrication (out of either chrome moly or mild 
steel tubing) for experimental aircraft, custom automotive 
frame and sheet metal fabrication and restoration, 
stainless steel kitchen and dairy fabrication, as well as any 
other application which might require TIG or stick 
welding.
There are any number of other reasons why the Invertig 
131 DC/HF belongs at the top of your short list. High 
frequency non-contact arc starting delivers operating ease 
which completely eliminates the possibility of tungsten 
contamination. The 131 also features touch start arc 
starting for welding applications where HF starting cannot 
be used. Remote foot pedal amperage control is another 
plus that makes your welding projects not just easier, but 
more precise. Also . . . amperage is infinitely adjustable 
from 5 to 130 amps, and a gas solenoid valve is standard, 
eliminating the hassle of manually operating a gas valve 
on the torch. 
The Invertig 131 DC/HF comes complete with a 12 ½ ft, 
9-Series super-flex high-performance TIG torch, foot 
pedal with 12.5 ft cable, a flowmeter with gas hose, 
and ground cable. The Invertig 131 has a one-year 
warranty and ships free anywhere in the Continental 
United States. So if you are looking for a high perfor-
mance TIG welder at an affordable price, look no 
further than the 131 DC/HF.

TIG Welding Machine Covers
Your HTP TIG welder is an essential part of your shop. 
So why not protect it with a durable, water-resistant, 
non-flammable machine cover? Made from polyester-backed 
marine vinyl, these covers are specially crafted to protect your 
machine from moisture, dust, and other harmful workshop 
elements. For convenience, each cover includes a series of 
cutouts that allow the TIG torch, foot pedal, and ground to stay 
connected while the cover is in place. Protect the finish of your 
TIG welder . . . it’s easy with an HTP machine cover.
TIG Torch Holder  #90190 TIG $17.95
Keep your work station organized!  This handy magnetic 
based TIG torch holder is an easy way to keep your TIG torch 
close at hand, but not in the way. Did you ever lay your TIG 
torch on the welding table, only to have it fall off and break the 
cup? The TIG torch holder is the solution! You can easily keep 
your torch close, and your fabrication area in order, with the 
HTP TIG torch holder.
HTP is proud to bring you our DVD, Welcome to the World of TIG Welding. This informative, 70- 
minute DVD really brings you up to speed on TIG welding. If you are thinking about purchasing a 
TIG welder, the money spent on this DVD may very well save you hundreds of dollars by helping 
you select the correct machine for your application. If you already have a TIG welder, the DVD 
gives you a through the helmet view of TIG welding.
The DVD opens with the different models of HTP TIG welders, and explains the differences between 
them (AC or DC, HF starting or scratch starting, remote amperage control—do you know what you 
need?) We then cover TIG torches and the correct assembly of collets, collet bodies, alumina cups,
and tungsten on the torch, along with specialty torches.
The DVD then goes into the front panel controls and explains slope up and down, post flow, final 
current, and pulsing. On the AC side, frequency and balance are explained in detail. Then, we give you
a welder’s eye view of the TIG welding process, looking through our Striker Digital helmet, as if you are doing it yourself. We start 
out by running a bead, then a bead with filler, butt weld, lap weld, and fillet weld, in both steel and aluminum.
If you purchase the TIG DVD, and then decide to purchase an HTP TIG welder, we will credit the purchase price of the DVD 
towards the purchase of the welder. So how can you lose?
