How do you light a rosebud torch?
- Separately purge both oxygen and fuel gas lines.
- Open fuel gas valve 1/2 turn.
- Ignite flame with striker.
- Increase fuel gas flow until flame leaves end of tip and no smoke is present.
- Decrease until flame goes back to tip.
- Open oxygen valve and adjust to neutral flame.
- Depress oxygen lever and make necessary adjustments.
Do you use oxygen with a Rosebud?
A rosebud is designed to use a lot of oxygen and acetylene gas flow. A cutting torch tip uses a lot of oxygen sometimes but a rosebud needs a lot of both gases flowing to keep it cool and to keep from popping back.
What is the oxygen pressure set at when using a Rosebud?
That depends, what size rosebud are you using? The general answer is 10 psi oxy 15 psi acetylene, for most tips, some larger tips will require up to 15 psi oxy.
What is a rosebud torch tip used for?
Uniweld’s Rosebud heating tips are your best tip choice for brazing, soldering, straightening, and heating. These tips fit Uniweld’s 71, WH250, WH550, and WH350 (Types 17 & 28 require F15 Adaptor when using this handle) welding handles.
What should my torch gauges be set at?
The recommended setting is for the fuel gas regulator to be set at 10 psig and the oxygen regulator at 45 psig. This recommendation applies when cutting less than 1.5 inch steel with the use of propane, propylene or natural gas.
What is the hottest cutting torch?
acetylene
The hottest most-versatile gas, acetylene, is very easy to use for all purposes. Pre-heat time for cutting and gouging is relatively short because the flame temperature is between 5,600 and 5,800 F.
Why does my torch keep popping?
Overheated Nozzle If the popping is only happening after you’ve been using the torch for a while, like maybe after half an hour or so, it might be because the nozzle is getting too hot. Turn off the torch with the torch valves. When the flame is out, open up the oxygen valve. Then dunk the nozzle in water.
What should acetylene pressure be?
In case the recommended working pressure settings are not indicated, safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of tip size. Simply adjust them until you get a neutral flame, but pay close attention to the pressure to prevent it from exceeding the limit.
What makes a torch pop?
The reason that an oxyacetylene cutting torch will pop and go out is because of a problem with gas flow. Usually this is either an issue with flow settings, a leak or blockage.
How much pressure do you use when using a Rosebud?
I have found that when using a rosebud, you need to use a higher pressure than when cutting, Start about 10 psi on Acetylene, If the torch pops loud, turn up the Acetylene a little more, but never higher than 15 psi, because Acetylene becomes unstable at pressures higher than 15 psi.
What are some common mistakes with a Rosebud?
Typical mistake with a rosebud is running with the flame too low. As mentioned above, flame front has to push out of the head, so you have to really get the flow up. Pressure on the guage makes no difference whatsoever if you have the torch valve clamped down.
What size propane hose for Rosebud burner?
FWIW: Nowadays, if there is preheating of welding work on tanks or structural, or heavy heating or hot forming of platework, the tendency is to use “atmospheric” propane burners (aka “weed burners”) rather than rosebuds. I run my 8 MFA rosebud with 1/4″ bore hose.
Can you use a rosebud with oxy-acetylene?
If you are using a rosebud with oxy-Acetylene, best operation require the gas velocity must be, on the low side, fast enough to prevent sparks or flame from getting into the mix chamber. On the high side, the Acetylene should not be above 15 psi and otherwise not too hot or too turbulent for your immediate needs.
