Guys/gals:

I recently bought a heavier-duty (used) torch to replace one that I
gaot in a starter kit. That original one would light just fine, but
then would make a loud pop and go out when you ramped up the O2 to
achieve a neutral flame. The new torch is doing exactly the same
thing! I have a trio of questions:

1) is this "blowback"? Based on my reading, I believe it may be.
2) could this be caused by low pressure on both regulators? My O2
regulator (again - cheap, starter-kit stuff) doesn't want to go much
over "5" - it gets really hard to turn. Thus, I just use 5, and tone
down the acetylene accordingly...around 3...
3) if this is the possible cause, can anything be done to fix this
regulator? I haven't torn it down, and I know better than to oil
it...what else can I do?

Please bear in mind: I am a beginner, and money is something of an
object. I intend to upgrade this gear in the future, but am looking
for at least a short-term solution! Thanks in advance!

If you cannot keep equipment that has the danger potential of oxy-acetylene
in good repair, perhaps you should not own it or attempt to use it!

A small cutting torch can run in the range of 5 p.s.i acetylene and 25
p.s.i. oxygen. You need to run higher oxygen pressures to provide the
"blow" for cutting.

A small cutting tiorch and its tanks also has the potential of blowing up a
fairly large building if not used correctly!- Hide quoted text -

Real nice, friendly response! My gear is NEW, and has been like this
since day one. Thanks so much for making assumptions about me! Tell
me though - when a person who comes out and says plainly that he is a
beginner and asks for advice, should you first tell him to no own or
operate it? Way to support the new guys! I'll be sure to forward
this to the frequent poster to this board that recommended me here -
he'll be pleased to hear about these "friendly" people he plays with.
