How do you set an acetylene torch?

How do you set an acetylene torch?

Open the acetylene valve on the torch handle about 1/8 turn, or 45 degrees. Light the torch with a spark lighter and adjust the acetylene valve on the torch handle and the oxygen valve on the cutting torch until the flame has no yellow areas and the center is bright blue and well defined.

What should oxygen acetylene torches be set at?

In case the recommended working pressure settings are not indicated, safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of cutting tip size. Simply adjust them until you get a neutral flame, but pay close attention to the acetylene pressure to prevent it from exceeding the limit.

What is the ratio of oxygen to acetylene?

Do you use more oxygen or acetylene? For maximum flame temperature in oxygen, the ratio volume of oxygen to fuel gas are 1.2 to 1 for acetylene and 4.3 to 1 for propane.

How do you light a torch without a lighter?

Place a striker underneath the gas nozzle to light the torch. Propane torches generally come with a lighting device called a striker. It’s a gun-shaped device with a trigger you can pull to spark a flame. Hold the strike up close to the torch head nozzle, almost right up against it.

How do you turn off an oxygen acetylene torch?

Stand away from front of regulator. Separately and slowly open the oxygen and acetylene cylinder valves. Also asked, how do you turn off an acetylene torch? Close the acetylene hand valve on the torch, then the oxygen valve. This extinguishes the flame and eliminates the soot. Tightly close the cylinder valves.

How do you light an oxy fuel cutting torch?

Lighting the Oxy-fuel torch 1. Turn the acetylene knob on the cutting torch about a quarter of a turn and light the acetylene. Make sure that the flame is up against the tip. If you light up the tip and the flame is away from the tip, decrease the acetylene pressure and let the flame come back against the tip. (Use your safety equipment.)

How much acetylene do you put in a cutting torch?

Pressure Settings Chart Thickness of metal in inches Tip size Pre-heat oxygen (PSIG) Cutting Oxygen (SCFH) Acetylene (SCFH) 0.125 000 3/5 20/25 3/5 0.25 00 3/5 30/35 4/6 0.375 0 3/5 55/60 5/8 0.5 0 3/6 60/65 6/10

How do you keep oxygen and acetylene from leaking?

Use a non-adjustable wrench to securely fasten both the oxygen and acetylene hoses to the torch. Having tight connections is extremely important because they will keep both the oxygen and acetylene from leaking. Close both torch valves. For the oxygen, turn the pressure-adjusting screw on the regulator until the gauge reads about 25 psi.

What should my oxy-acetylene regulators 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.

When to add oxygen to oxy acetylene torch?

After adjustment of the acetylene valve add oxygen using the mixing valve. Start to mix it when valves are fully closed. Full open mixing valve slowly until you get the neutral flame. Once the flame is adjusted, then the torch is ready to roll. Let’s cut some metal. Keep everything in position to avoid damage and cut safely.

How to test acetylene in a cutting torch?

Slightly open the valves for both oxygen and acetylene on the cutting torch, but make sure that the valve for acetylene is not open by more than 1/8 of a turn or exceeding 45 degrees. Do a leak test on all the connected parts using a solution specifically for leak testing or a paste made using dissolved Ivory soap.

Which is the best cutting torch for oxyfuel?

Due to the acetylene present, the flame produced by the cutting torch is the highest among all oxyfuel cutting processes. This means you can make cuts much faster and of better quality than the other methods. How Do You Set Up an Oxy Acetylene Cutting Torch?
