Here's a thought... and I may try to build and test this one...

That thumb-lever hits two microswitches in progression. 1st turns the arc on at a background current (by voltage divider in the pedal circuit) at just more than the merest touch. 2nd goes to peak current by shunting the voltage divider. True manual pulse, rather than simple on/off. Perhaps even a tiny box with an adjustable pot to set the background as a percentage of max?

For where the result must meet a code?

This could be easily done...

Hmmm.

I like that idea alot - electrically it's very simple as you say ( once you measure foot pedal resistance range )- not so sure about making the torch switch enclosure to house the 2 switches without it becoming big / bulky / difficult to hold - if you have thoughts on anything that can be converted or if you do make one then I'd be very interested to see the results - I'm sure many others on the forum would as well - ( maybe you should patent & sell it ! while your at it we're still waiting for news on a " Tig glove " !

CK flexloc with CK switch. I like the fact that it just clips on and I can spin it around to get a comfortable position with both the torch and switch. I thought it would be too big but it was actually really easy to get used to.

And this is what my cat thinks about the setup

Very interesting. Any chance of a photo? Do you have it set up as Steve S's idea: first set of contacts give background amps, whilst the second set give peak amps? What technique do you use with your setup?

Many thanks

I just have it set as an on/off switch. Never saw the need to do otherwise. Not a bad switch for $18 and change!!!
