gas welding torch cleaning
 
So I have been having issues with my gas torch. When trying to weld I set the flame and it works great for about 60 seconds or so, then the oxygen levels start to drop. I started taking things apart to find the cause, and found a white build up inside the torch body on the oxygen side. What should I use to clean inside the torch body itself? Brake cleaner, rubbing alcohol, tears from a sweat shop worker?

Assuming the torch is brass - I'd say a Qtip and solvent to start. Compressed air to follow - disconnect both ends first. Followed by fine copper picture wire run though the passageway, and blown out again.

Excellent torch, but all torches are susceptible to accumulations from the fuel gases over time - and over the volume that they flow.

Thanks Kent, really appreciate your responses, going to clean it out first thing in the AM and test it out.

Hi Mike. When we were spending most of our ill-gotten insurance broking income getting our boys towards the pointy end of local karting, chasing the last 1/10th of a horsepower was crucial. Carb cleanliness was a big part of this - two stoke fuel residue gets quite 'gummy'. To help with the cleaning, I bought a cheap ultrasonic cleaning bath from the local electronics store - around $200 I think. We used Simple Green detergent at around 5-10% as a surfactant. A gentle 30 minute bubble in the bath brought everything up like new and didn't damage any seals.

I wonder if something like this could be used on your torch?

Iv'e since used the cleaner on all sorts of things to great effect.

I'll chuck some of my OA tips into the bath later today and post a before and after pic.

I have one of those ultrasonic cleaners from harbor freight.... didn't even think of it lol. I ended up cleaning it per Kent's instructions, I also took the gas saver off and installed new hoses. Been wanting to do that part for a while. Fired it up and it seems to be good. Thanks for the help guys!
