I have been using a natural gas tip on my Hoke for years. During
these years I have used both natural gas and propane, the tips work
fine for both gasesand I personally like the multiple port form of
the natural gas tips better than the single port. At this point i'm
back to using propane even though there is a gas line in the wall
behind my bench. I do a lot of platinum work and the propaneburns
just a little hotter than the natural gas. Or maybe it has to do
with the pressure?
