How do you start and shut down the oxy acetylene operation?

1. Separately purge both oxygen and fuel gas lines.
2. Open fuel gas valve 1/2 turn.
3. Ignite flame with striker.
4. Increase fuel gas flow until flame leaves end of tip and no smoke is present.
5. Decrease until flame goes back to tip.
6. Open oxygen valve and adjust to neutral flame.
7. Depress oxygen lever and make necessary adjustments.

Thus, What is the last step in shutting down the oxygen fuel torch? Close the torch valve. Now go to the source and turn off the cylinder valves. Purge the pressure from oxygen line by opening the torch valves one at a time until the gauge pressures read zero. Close the torch valve.

Additionally What pressure should oxygen and acetylene be set at for cutting? Recommended oxy/acetylene cutting tip pressures vary with size. If you have no manufacturer setting- information, and are cutting less than 1 1⁄2” thick steel, set the acetylene regulator for 10 psig, and the oxygen regulator for 40 psig.

How do you turn on a cutting torch?

How do you close down the welding equipment safely? Closing Down

1. Extinguish the flame by first closing the acetylene valve on torch, then closing the oxygen valve.
2. Close both oxygen and acetylene cylinder valves.
3. Open torch valves one at a time to release pressure in the regulators and hoses.
4. Re-set regulators to zero outlet pressure by unscrewing adjusting screw.

What are the steps for shutting off the torch?

How do you purge a cutting torch?

How do you use a cutting torch step by step?

What are the steps to shut down a torch?

Which valve do you first close when extinguishing the flame on the torch?

Extinguish the torch flame by closing the acetylene valve first and then the oxygen.

What are the settings for oxygen and acetylene?

Recommended oxy/acetylene cutting tip pressures vary with size. If you have no manufacturer setting- information, and are cutting less than 1 1⁄2” thick steel, set the acetylene regulator for 10 psig, and the oxygen regulator for 40 psig.

How do I turn off my oxy fuel torch?

Shutting Off The Torch Close both the Oxygen and Fuel Tank Valves completely. Open the Torch Valves, one at a time, to bleed the hoses. The pressure shown on both Pressure Gauges should drop to zero. Close the torch valves.

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. So, there is far more oxygen being consumed when using propane than acetylene. Despite propane being less expensive than acetylene, this is counteracted by the higher oxygen consumption.

How do you extinguish the flame after using gas welding?

open both torch valves to vent the pressure in the equipment. close torch valves.
…
After an unsustained backfire in which the flame is extinguished:

1. close the blowpipe control valves (fuel gas first)
2. check the nozzle is tight.
3. check the pressures on regulators.
4. re-light the torch using the recommended procedure.

How do you light adjust and shut down an oxy acetylene torch?

1. Separately purge both oxygen and fuel gas lines.
2. Open fuel gas valve 1/2 turn.
3. Ignite flame with striker.
4. Increase fuel gas flow until flame leaves end of tip and no smoke is present.
5. Decrease until flame goes back to tip.
6. Open oxygen valve and adjust to neutral flame.
7. Depress oxygen lever and make necessary adjustments.

How do you set oxy acetylene for brazing?

What is the proper order for setting up the welding apparatus?

1. Secure the cylinders; 2. “crack” the cylinder valves; 3. Connect the oxygen regulator and hose to the oxygen cylinder; 4.

How far should acetylene valves be turned on?

An acetylene cylinder valve shall not be opened more than one and one-half turns of the spindle, and preferably no more than three-fourths of a turn.
