Hi-Heat is the registered (old and no longer registered) trademark
for a Gas/Air Jewelry torch.
The model that I acquired is a Model D with two (2) tips. One tip is
#20 Gas and Air. The other is #10 Gas and Air. The handle looks like
it would use rubber hose pressed on the the tapered hose fittings
with rings to hold the hose.
I need some operating instructions perhaps someone has a owners
manual that they would be willing to share in the form of a copy.
In the absence of that, I need to know the best way to hook it up? 1)
What pressure should the Propane be run at?
2) What pressure should the compressed air run at?
3) I understand Oxy can be used also and is there a difference in
the pressure that be used for Oxy vs Air
If you have an electronic copy available, you could send it to rwade
