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
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. Bugs
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.

(clip) ^^^^^^^^^^^^^^^^^^ 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.
