Posted By james2000 Hi any body could tell me concerning types of flashback arrestor on welding set, I have seen one type like small pipe and one type in fact attached to torch.and has written on (flashback arrestor) Which one is correct type of flashback arrestor?? and where is the best place to install that??? Thanks james

Posted By Mitch James, Never seen one on a torch either this would cause 2 immediate problems, firstly manipulation and the effect this would have on the safety of the operator and secondly some have external mechanisms which could be inadvertently activated while wrestling with the torch with an arrestor fitted. Fit them immediately after the gauge for clarification before anyone asks cylinder, gauge, arrestor, hose, torch. Mitch

Posted By Anthony Edwards James, I have only ever seen flash back arrestors at the gauge end of the hoses, which activate if a flash back occurs, (they then can be reset once the problem has been resolved). The only tubes I have come across at the torch end of the hoses are hose check valves, which are a one way valve again to help eliminate the flash back. I would speak to a reputable supplier and ask which are most suitable to the system you are using. Hope this helps Nutty
