I’ve been using a Smith Little torch with disposable propane tanks and an Extreme Oxygen EX-05 oxygen generator in my home studio for about six months now. I’ve never had any major problems with it, but today my flame keeps blowing out on my when I introduce the oxygen. I haven’t used the torch for three days; it was working just fine before this. The problem is currently extremely consistent – happens each time I try to make a flame.
I’m a beginner when it comes to troubleshooting torches, so I’m not sure what variables I should be looking at. I replaced my propane tank with a new one in case it was low. I switched out torch tips from a #6 to both #5 and #7 with no difference. I bled all my lines a few times. I rarely have my oxygen generation pumping more than 2 LPM of o2. I don’t know what the propane is at because I don’t have a gauge on that regulator.
Anyone know what’s happening to me here? I suspect the answer is obvious, but I don’t know what it is! Any help appreciated – I have a few projects due to clients this week and am up a tree.
