I have just picked up a med duty Victor torch/cutting set and I had some
questions...

My kit doesn't come with backflow/arresters and I'm wondering if I should
worry about using the torch without them? I'm using the smallest sized O2
and acet bottles my supplier carries so I don't know if that makes a
difference from a pressure standpoint?

The manual that comes with the kit suggests using the arresters but I wanted
to ask from a 'first hand experience' perspective as to whether or not I
truly need them? I don't want to have a fire or blow myself up but I've
been using portable 1lb MAP torches for years and never had a backfire,
problem, etc...

Is there any other advice you could offer a noobie like myself? My first
two projects are going to be fixing the exhaust on an old project car and
building a welding cart. Should I use coat hanger to weld the exhaust with?
I've heard this works very well.

Can I weld the exhaust with the MAP torch or is it not hot enough? I'm
itching to get this torch fired up but I have visions of causing a problem
without the arresters in place...


Thanks for any and all advice.
Andrew.
