I’ve got a chance to buy a new oxy-acetylene rig at quite a modest
price: dual regs, torch, hoses, small rechargeable tanks, striker
and all. Oxy-Acetylene is somewhat attractive to me because I’m
familiar with it from general shop use and it’s got a lot of
versatility in that regard. The torch that comes with the rig is just
a basic two tip affair so I’ve been looking at other, third-party,
torch options for jewellery making.
What I’ve noticed is that a number of oxy-gas (propane, nat-gas,
etc) torches offer the option of needle tips for ultra-small flames
but I haven’t seen the same for oxy-acetylene. Case in point, the
Hoke torch comes in several fuel gas variations and has a set of
needle tips but those carry the caveat that they “are not recommended
for use with acetylene”.
So, my question is, are these super-small tips something
oxy-acetylene simply can’t do? If so, why not? Or does the
oxy-acetylene mix require something “special” in order to go that
small (as in “special” tips)? Or have I simply missed something and
needle tips are no problem for oxy-acetylene?
As usual, all input is welcome and appreciated.
