I've got a Victor O/A rig. With ordinary brazing and welding tips, everything is working fine, and is work-safe. The torch handle is a 'standard' Victor (medium-size) one.
For cutting, rather than a separate torch, I have the common set-up where the cutting head fits on the welding-torch handle. My cutting head was reconditioned by a reputable company about year and a half ago. Then it worked fine. Since then, I've put no more than 90 minutes of use on it, generally in brief sessions of 10 minutes or so.
But now the oxygen-control valve (the one high up on the cutting head, not at the hose end of the handle) seems stuck. When the torch is lit - with the main oxygen valve fully open, and the oxygen-control valve supposedly closed (as in normal procedure) - the flame shows a lot of oxygen right from the start! No yellowish, smokey, loose, flame to begin with. That is without squeezing the extra-oxygen lever.
I'd send the cutting head back to the company that rebuilt it, except: a) they are 500 miles away; b) they might not believe how little time I've put on the head since the rebuild; c) I'm curious about how the cutting-head mechanism work, and thinking I should be able to fix something that is probably simple.
Is there a simple explanation and maintenance procedure?
