Stud welding with common tools?

[teletech]

I'd love to weld a 1/4" threaded stud to a plate.
I own a stud-gun resistance welder for automotive bodywork, but of course that doesn't have the power.
Online searches tend to talk about capacitive-discharcge or other exotic machines, so that's out as well.
I'm thinking along the lines of using a spot-welder or my TIG welder as a resistance welder.
Has anybody cracked the code on this?

Rivnut maybe the best option for your application then red Loctite in a stud to it or tack it together.

I use adhesive mount fasteners.

It's expensive but it isn't. You're looking at $75 to $150 to install your first fastener. Fasteners are a few dollars each. The adhesive is about $35-45 a cartridge lasts only a short time after it's opened.

why not just drill/tap the plate , use a double-ended manifold-style bolt or threaded rod cut to your needed length, and spot-weld it from turning? If your stud-gun welder cant do it, maybe since you don't indicate the thickness of the plate nor the expected torque of the nut to hold whatever you are mounting to it ,, "red" threadlocker (permat*x) holds pretty good up to a certain torque point

Adhesive-bond might be a course of action, but it would have to be a stud rather than a nut.
It's armor plate, so drilling, tapping, and riivnuts aren't going to work for me.

Studs are available. This is a battery charger install I did a few years back.
