I have acquired a “HI Heat” model D gas/air torch (at a garage sale) and would like to use it with propane. Do I need a regulator in addition to the one on my 5 gallon propane tank? If so, what’s the recommended psi setting? Also, for the air side, is compressed air what is called for and what psi might be appropriate?
I would be most appreciative of any help and advice.
