What should the low pressure working side
have for a pressure gauge? Mine is in
increments of 10. (Oxygen)

It's very old, very. Does this have anything to
do with it?

I just went through a video course, and the
pressures called for welding are in the
3 to 7 psi range. I couldn't get the regulator
to go that low.

Is it possible to rebuild a regulator? Is it
worth it?

Thanks.

3-7 psi is pretty lightweight welding with small tips. If the
regulators won't hold those pressures, you can easily get them rebuilt
through most any welder's supply company. Cheap single stage regs. will
always be hard to adjust. Two stage regulators are better.

Replace the gauge, I did it, cost around $15 for an oxygen gauge that
went up to 60 psi max. I got it from my local welding shop. Then I
could read lower pressures. The regulator may hold lower pressures
fairly well, but you can't tell with a 200 psi gauge.

Do you mean that the regulator jumps past the proper pressure range when you
try to set it, or do you mean that the gauge can't be read in that range? I
have been welding for years, and I never rely on the gauges at very low
pressures. If you know how, you can very easily adjust the gasses from the
appearance and sound of the flame.

With the proper tip in place, turn up the acetylene pressure until you get a
flame that wants to separate from the tip. Then back off a little, so you
have a stable orange flame. It will make a clear sound, above a whisper,
and not a whistle or roar. Then turn up the oxygen pressure, and you will
see the long orange flame get shorter, and two inner cones will appear--a
long one and a short one. Keep adding oxygen until the long cone gets as
short as the short cone.

That's a balanced flame. Your gauges will probably be within the very low,
unreadable part of the scales.
