Oxy acetylene tip going red hot

[Farm789]

One last question once I put the oxygen on it pops every 2 seconds exactly the same time every time I have tighten the tip up ats still doing this any idea why it’s doing this? It’s a obviously a brand new tip and torch cheers

That don’t sound right. Where are you based? I’m wondering if there’s anyone local on here who could cast an eye over your setup

Perhaps @Mid Wales welder isnt too far aeay

I will get my uncle to come and have a look at as he is a welder but isn't very approachable. i might get a video of it and put it on here.

@hypertherm69 if you still need help let me know, pretty busy at the moment but if you’re not to far away I’ll swing by, I’m near Newtown.

Get a video of how you are setting up and lighting the torch.

I’ll do another video tomorrow of proper setup.

IIRC, any time the torch started popping after lighting up was down to dirt on the surface of the tip or in one of the nozzle holes. if you haven't already, get yourself a set of tip cleaners, am invaluable tool IMO.

Seem to be loads of clips on You Tube, most of which show a correct lighting up process, but none too happy with one who switched the oxy off before the fuel gas . . . not the way I was taught. Spark lighters are the best way to go but there's always the option of turning on the fuel and striking a quick arc on a bit of scrap plate to light up. Handy if you're not a smoker and your spark lighter isn't to hand.

Brand new setup, brand new nozzles. No dirt is causing that.

Oxygen always goes off before the fuel gas. Unless you’re experiencing a flash back or sustained backfire. Then you switch the fuel gas off.

That seems to be the modern way. I was taught fuel on first, feed oxygen into it then reverse to shut down.

Few older guys I’ve worked with seem to shut fuel gas down. Books will give conflicting advice also so without knowing the theory for each it’s hard to know what is correct

Not the way that I was taught. Fuel on, light, O2 on, fuel off, O2 off.

When was that out of interest? I would have been taught mid 90’s.

just wondering if it’s a time thing?

 

[Seadog]

1976

 

[James1979]

Maybe that’s it then. Guys who I’ve seen do it your way have all been older than me.
Wonder if there was a shift in thinking?

 

[Seadog]

It makes more sense to me. You burn off all of the ignitable/explosive fuel gas first.

 

[Brad93]

It depends what train of thought you follow. In the states, and specifically Victor, they tell you to shut the oxygen down then the fuel gas.

If you go back over british literature they say shut the oxygen off.

I've got a victor torch so ill do it as victor say.

 

[James1979]

I thought oxygen first was so that you didn't leave the oxygen on in error?

Its also easier if you are going to make another cut as you dont have to re ignite it, just introduce the oxygen again.

 

[brightspark]

i just shut the fuel of first then the oxygen otherwise you just get a sh..itty flame doing the oxy 1st. its been fine in 45 years so il carry on doing it

Not the way that I was taught. Fuel on, light, O2 on, fuel off, O2 off.

similar to how I was taught, firstly to crack the oxygen / acetylene to make sure the valves weren't stuck on the mixer, just a quick open and close, then to light - fuel on, light - sparker, O² on slowly up to whatever flame was needed, then to shutdown fuel off, then O² off,... then bottles off and wind back regs...

still do it that way now.
