Has anyone seen a micro plasma cutter? If it's just a DC high current arc, with pressurized air pushing through nozzle seems like I could probably make one myself with these salvaged transformers and capacitors I have around.
I was curious about making something small scale. I would like to try vaporizing paths on copper clad.
They certainly exist.
The power supply looks like a small arc welding set though.
I am not sure if it is something that could be made from bits lying around though.
My understanding though is that a jet of air blows through the cut, not sure if surface ablation would work.
Edit.
Spark erosion maw work though.
I do not believe it is as simple as you make it out to be. To say it is "just" a high current arc with pressurized air is ludicrous unless you are a BSEE with a degree in metalurgy.
Good luck with that.
This is "General Electronics".
There is nothing "General" about this application.
That is not to say anyone couldn"t build it if given the schematic and parts list with vendors and part numbers . Short of that, it"s not going to happen.
You are seriously under estimating the amount of specific knowledge required. Your best bet is to find a "kit"- like project online with all the design work done for you.

I'm posting to ask for curious advice. I did not see a sub section for micro plasma torch setup to post a new thread on. I do not have an inventory list, part diagram, business model. Just wondering if anyone had experience with this topic they could comment on.
Did you try google ?

They exist but the PSU alone will likely cost 1000 +.
I don't think the fabrication of the nozzle gun is trivial either.

I found a few people take batteries with paper-clips, cutting aluminum foil, soda cans. Another example where people take arc-lighters or taser/stun parts fit them to gator clips with copper probe and cut through paper with a metal base plate.
And of course I found complicated projects where they explain all the parts needed to make their own professional grade standard size plasma cutters.
I haven't found too many other variations. I guess that is all I probably need.
