Questions: Is there a difference in these tips? Are different
orifice sizes needed for Natural/Propane gases or do the sizes
Yes, there are differences in the tips. The natural gas tips have
a “flower bud” orifice, rather than a single hole orifice. I
personally use a Hoke torch (designed for natrual gas) with
propane. So I am actually using it with the “wrong” gas. I did
this so that I could switch to natural gas at a later time, and it
works. Actually, propane only burns 100*F hotter than natural gas.
I use the precision set with propane for 80% of my fabrication
work. The “flower bud” tips are ideal for casting and platinum
Questions: If I get the precision set, is there any need to get
the standard tips or do they also overlap? Will the precision tips
work with both my gases?
Yes, if you get the precision set, I recommend getting the
standard natural gas tips as well. Yes, the precision tips will
work with both gases, as will the standard natural gas tips.
I have the Vigor catalogue numbers for those three tips. They are
Please note, that the Vigor company has since been bought out by
Grobet File company and I 'm not sure which of the numbering
systems are now being employed. Grobet File company used the
H.R./GFC numbering system and Vigor used it’s own. If you contact
a local supplier that has a current catalogue, they can advise you
as to which numbering system is being used.
Some additional hints about the Hoke Torch…
I set my gas pressure at 6 psi, and the oxygen somewhere between
18 and 20 psi. I might suggest installing check valves somewhere in
your the torch system, as the Hoke torch does not have a built in
check valve arrangement.
Good luck, and let me know how it works out for you,
