Does the torch happen to say lifetime on it?
Also I would eliminate whatever those cobbled ends are on that torch. There should be no need to use any Teflon tape on a torch setup. I have seen a little tape used on the pressure gauge dial threads on the regulators.
Not sure about the lifetime, but I'll take a look. What exactly would that mean if it does say lifetime? That stuff is all extras I recieved from my uncle. I have a brand new firepower oxyfuel 350 setup on the way. I was just wondering if I should use that oxygen arrestor on my tank when I get the new setup. The setup already comes with the small arrestors anyways. I was also reading the oxyfuel 350 torch is compatible with multiple fuels like propane. The tips I know must be changed. Does that mean just the torch is compatible, or is the regulator compatible with propane as well? I've read propane regulators are compatible with acetylene, but not the other way around. Then I've read acetylene regs can be used with propane. Which is it?
