Torch Help
 

ok I have used torches before. the last time was 10 years ago. I know your suposed to adjust as and oxygen until the blue flame gets to ~1/4" in length.

my problem is that my blue flame never becomes an arrow shape. I see all 5 little streams of blue flame. do I not have a cutting head on it and just a brazing head or some thing?

no matter how I adjust the gas and oxygen mix the small flames never connect to make one larger one.

That would be correct for a cutting tip....5 small arrow shaped flames, they wont merge into one.....

Try find a pic for ya...

if its a rose bud the blue wont all touch wat are u trying to do with the torch

poor pic here:

ya long horn if he says its not a cutting tip but has 5 flames its probaly a big rose bud tip

Is the tip clean?

I cleaned it up. I thought you were supposed to get all the lines to meet?

I was just trying to play with my new toys and couldnt cut a 1/4" piece of plate steel. I'll have to try the right flame. I tried it a bunch of different ways and couldnt get it to cut.

I'm not familiar with the different tips. what is the best tip for cutting?

well does the head have a lever if its a rose bud or like a welding tip u aint gonna get nothin cuut with 1/4 inch a #2 would do great

yeah there is a lever. it looks like the second picture that longhorn posted.

Look here:

You should slice through 1/4" plate easily.


BTW, nice pics Longhorn...lol

my tip looks nothing like that one. it has a hole in the center and 5 or 6 smaller holes around the center hole.

that is a normal cutting head tip.................they all will come to a point nice and blue but wont merge

ok if I get a chance tonight I will set it up properly and see how it goes.

let us know man

It sounds like you don't have enough oxygen.

Make sure your acetylene regulator isn't up too high. Keep it at about 10psi.

Only open the acetylene tank valve it about 1 1/2 turns.

Open the oxy tank valve ALL the way.

Open the acetylene valve on the torch just until you get minimal soot.

Open the oxy valve on the torch's base fully.

Use the oxy valve that's up further on the torch to adjust your oxy level.

I can't remember what the oxy regulator pressures are supposed to be.

goo info. I'll have to clean the lenses up on the regulators. they are plastic and hard to see.

I found this-

Common gauge settings for cutting:

1/4” material Oxy 30-35psi Acet 3-9 psi
1/2” material Oxy 55-85psi Acet 6-12 psi
1” material Oxy 110-160psi Acet 7-15 psi

ok I I did tons of reading and have the tank pressures set right. I cleaned the head (it didnt seem too dirty.

at this point I am ready to light it up. From what I read yoou turn the gas on just enough to light it and then turn it up until the flame burns "clean" (which it never does there are black floaties everywhere). Then crack the Oxyegen until desired flame is reached. well as soon as I crack the oxygen it snaps and the flam goes out (80% of the time) or if I get the flame to stay it pops when I press the handle to add more oxygen.

what the hell am I doing wrong?
I don't ever remember having this much trouble when i have used them in the past.

Also I read that the popping usually occurs when one of them is turned of before the other and that it shouldnt be done. but I cant remember which. but this doesn't explain my pop

sounds like to me you have toooooo much acceteline when you introduce the Oxy

try about half that on accetelene..........yes it will be very black with soot. (substoikemetric burn) then add the O2..............you can always add more accetelene then more o2 after that

u dont have enough actelyne tat suker should look like a mine flame throuwer, light it with it barley open open the valve on the torch half way up,not the bottel, then star opening the oxy vavle on the torch get it close to pointy the hold down the lever and fine tune the oxy,
ur actlyne bottle is standing strait up right and if u already opened it all the way once it could be unstable and the liquid(acetlyne is a liquid) could have cloged up ur hose:U:

ok the way i read it was open the bottle around a 1/4 to 1/2 turn than open the gauge valve until the pressure reads 3-8 (for 1/4" steel) then open the oxygen tank slow at first than the rest of the way . then open the gauge valve all the way.

both bottles are straight up and always have been except when I transported them but they sat for 24 hours before I even hooked the gauges up. was that bad?

the valve that controls the third knob on the handle that controls the oxy when the handle is down what should that be set like?

I was wondering if you have some crusty in your fittings. Sometimes dirt get in there and fouls things up some. Or you may just have a bad tip.

You 2 knobs at the torch base. Acetylene and Oxy.

Make sure the Oxy knob up further on the shaft is shut.

Open the acetylene knob at the torch base a little bit. Just enough to light and get some soot but not a ton.

Open the Oxy knob next to it All the way.

Then open the Oxy knob up on the side of the torch just enough to get your flame set.

I think I figured the issue out.

when I tried this weekend I noticed that after I set the pressure on my gas I did the pressure on my oxy.
I grab my striker and cracked the gas valve and looked at the gauge for the gas and there was not pressure. so I turned the valve off on the handle and looked at the gauge again and it was rising. so I cracked the valve again and it dropped to zero again. so I think I might have a regulator problem or something.
isnt the pressure supposed to stay pretty constant?

Should never move. I can't tell ya what it should be right now without lookin at my guages but it should never move. I don't do any weldng with my torches anymore, just for cutting and bolt removal but I haven't adjusted my pressures in years. The setting there on does everything there is.

yeah i wont do any welding with it I just want to cut stuff
