Done overhead on thin aluminum and steel, but no other metals.Used all sorts of TIG machines since 1972.
Inverter models helpful.

Old Miller Synchro works fine, with hifreq. And the late models, too.
Footswitch is fine. Thumbslide okay.
Elbow prop/slider bar helps steady the hand, and less tiring on long welds.

Knee action on pedal takes a pillow/shotbag/spare helmet.

Hot splatter, drips not fun.
Spray water bottle handy.


(Journeyman/ lead welders agree: even when in contact with molten metal - you finish the weld.)
