Since you can't use oil based products on Acetylene torches, what would be the best way to keep your torches and tips clean?
What is used as a thread sealer on the stems? I can see something that looks like graphite but I can't tell for sure.
What would you use as a lubricant for the valve screw?
Has anyone ever changed the diaphragm in their own Oxygen Regulator?
