TIG Machine advice requested

[dodger]

The community workshop I'm a part of just lost its TIG machine (the owner moved out ), and I'm looking for a TIG machine. I need it mostly to weld steel tubing (thin wall, from .1mm up to .25 inches). I really don't have the money right now to drop the $2000 on an Miller. Anybody have any experience or recommendations or experiences on less expensive options?

.1mm as in .004"??? Are you welding aircraft parts? That must be a typo?

[dodger]

The .1 mm is not a typo. I'm welding bicycle frames. Though that is at the extreme end of how thin they ever get.

What material is strong enough even for a bicycle frame at .004" thick?

These tubes of carbon are usually only a few nanometres wide, but they can range from less than a micrometer to several millimeters in length

I am interested to see somebody try and weld that

I want to see a bicycle with a .004" thick frame made out of anything.
