What are TIG Inverters?

What Exactly are TIG inverters?

There are complicated explanations of how a TIG inverter is able to convert raw AC power into smooth welding current but essentially,  a TIG inverter is a smaller and higher tech version of an older Transformer style Tig welding machine. TIG inverters are lightweight and portable.

Here is a video where my friend Brad Goodman uses the PrimeWeld TIG225X TIg inverter to weld an aluminum lap joint using the pedal pump technique.

A short story about my first TIG inverter

When I was learning to tig weld, tig welding machines weighed 800 lbs and were almost as big as a refrigerator.

TIG inverters came along and totally changed the game.

A 225 amp tig welding machine that weighs around 50 lbs can cost less than $1000 and can be delivered right to your door? 

And with all the videos that I have available here on weldingtipsandtricks.com and also on welderskills.com

You can learn to tig weld in your own shop or garage.

I bought my first tig welding machine in the early 1990s to start my side hustle welding business.

It was a miller syncrowave 250 and it was a great machine,  but not portable at all.

And it needed a 100 amp breaker for welding aluminum thicker than 1/8” thick.

When I moved my welding shop from an industrial building back to my garage I  didn’t have a 100 amp circuit.

Right about that time was when TIG inverters that could weld both AC and DC became available. The only 2 choices I knew about back then were the Lincoln Invertec v205t and the Miller Dynasty 200.

So I sold the syncrowave 250 and bought a Miller Dynasty 200dx and mounted it on the wall of my garage welding area to save floor space.

That worked out really well for me for a few years and I made a lot of money with that Dynasty 200.

The latest version of the Miller Dynasty 200 is now called a dynasty 210 and at the time of this writing (June 2023) is currently over $6,000 for the machine alone without torch or foot pedal.

Well guess what?  All the jobs I ever did during  my side hustle days using that miller dynasty 200 could be done using a primeweld TIG225 for around $900 or a CK Mt200 at $1995.

Miller makes great tig welding machines and I still own a Dynasty 280.

All I am saying is there are now other options for folks wanting to get into tig welding for way less
