Oxy acetylene tip going red hot

[Farm789]

I have recently got a oxy torch and when cutting the tip goes red hot very quickly was wondering if the acetylene bottle regulator being set to high was the reason for this cheers?

Bad tip or gas pressures way way off. In my experience though it’s a bad tip where the flame front is not in front of the cutting tip, but burning back up inside the tip.

I sounds like it needs cleaning, have you any files?

as in post 2 worn nozzle or holes need cleaning out if damaged . you can get a set of cleaning prickers to run through them it may helphttps://www.zoro.co.uk/shop/welding-brazing-and-soldering/nozzle-cleaners/153391-nozzle-cleaner-set/p/ZT1000097X?utm_source=google&utm_campaign=pla%2B%7C%2BWelding%2C%20Brazing%20%26%20Soldering&utm_term=ZT1000097X&utm_medium=pla_css_3&targetid=aud-899587814867la-393891165330&loc_physical_ms=9046800&dev=c&gclid=EAIaIQobChMI6sTD5czz7AIVFO3tCh1QdQNQEAQYAiABEgILbfD_BwE

Usually once a tip has got red hot they’re pretty shot and need replacing.

Thank you I assume it’s the gas pressure is way off as the tips are new and look clean

Ye the tip has gone blue colour so I assume it’s rubbish now. I will have to get a file

I would have thought anyone that knows how to use oa cutting torch would also know the difference between a cutting flame or blowback and have turned it off long before the tip was cherry red.

Cheap tips can often be the culprit.

get yourself a copy of Murex: Basic Safety With Oxy-Acetylene.

make sure its got the right tip for the gas your using would be high on my list ,,, lots use propane and the switch to acet or visa versa can catch you out , numbers on the nozzle check it , or just start with a new one to suit your gas
make sure you have a blow back / flame check on the set if its second hand , farmers usually dont bother , but if your having bother it could be a life saver ,,, literally .

It’s a 1/16 tip dunno if that make a difference. Originally bought the kit it was for propane but I bought a acetylene regulator, hose etc and now use that. Do torches often have flame checks things built into them or am I going to have to get some. The manual it came with says 1/16 and acetylene pressure so I assumed it would work. Cheers

Thats a propane tip?
