Help me explain a conundrum (new TIG inverter)

Graham, I tend to agree with you. Yes, about the only thing that could matter is indeed load inductance. I also suspected the same (see my webpage), and I am glad that you place your more informed opinion in the same direction as my poorly informed guess.

The questions in my mind is, just what exactly happens in the circuit so that load inductance plays the role that it does, and how would this possibly translate to welding.

Thanks a lot!

No, but I know where to set the volume control (-6dB, to be precise) to *ensure* no clipping.

Or do you actually use the volume control like most people, based on your

Yes.

I simply refuse to believe that more than a handful of people do actually

Me, too! :-)

Maybe I missed it but I guarantee you that you will get far more help once you post the schematics somewhere. It is hard to discern from the picture but it looks like oscillation along with ringing. Oscillation can be a killer.

Here's the schematic that I want to have:

It is similar to what was used for original question, except that I did not then have the diodes on the left.

Where's the inductor made of the roll of 12Ga wire?
