How do you turn off Oxy Acetylene?
Quote from the video:
Quote from Youtube video: Turn it off as you see it's starting to feather mixing valves closed now we're going to slowly take away the fuel until recess is back in to the tip.
When igniting an oxy acetylene torch which valve should be turned on first?
Do you turn on the oxygen or acetylene first on an oxy-acetylene cutting torch? Starting up the oxy torch is easy once you’ve done all the regular safety checks. You’ll have to set up a torch. You will have to purge both valves separately, and you can start by turning on the fuel gas valve by 1/2 turn first.
Do you open oxygen or acetylene all the way?
Oxygen
Oxygen cylinder valves must be opened all the way. Do not open acetylene cylinder valves more than 1 turn (1/4 to 1/3 is usually enough). Turn pressures into gauges gradually. Always use an approved friction striker, never use matches or a cigarette lighter.
How do you run an acetylene torch?
Quote from the video:
Quote from Youtube video: Hold the striker against the tip of the torch with the lighter Cup between the torch. And you flick the striker to create the spark that will ignite the gas at the tip of the torch.
How do I adjust my torch settings?
Quote from the video:
Quote from Youtube video: Now obviously the first thing you do is turn your bottles on on the acetylene. All you need to do is open this valve up about 1/2 to 1/4 turn a pair on oxygen.
Why is my cutting torch popping?
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.
What is the best way to light an oxyacetylene torch?
Quote from the video:
Quote from Youtube video: When the torch is lifted from the cradle the gas supply is turned on to light the torch pull the nozzle backwards through the flame it's important that the nozzle is pulled backwards.
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.
What pressure should oxygen and acetylene be set at?
For the oxygen, turn the pressure-adjusting screw on the regulator until the gauge reads about 25 psi. For the acetylene, turn the pressure-adjusting screw on the regulator until the gauge reads about 10 psi. It is very important to test for leaks before starting your project.
What pressure should I set my cutting torch?
The gas pressures should be set at 3 to 5psi for Acetylene, and 20 to 30psi for the oxygen, but when you squeeze the oxygen lever after the initial flame adjustment of the preheat flames to neutral just to a point where the feather disappears,the oxygen cutting stream should be visible and at least 4 inches in length …
When shutting down the oxy acetylene torches which gas should be extinguished first?
If you shut the torch off by shutting down the oxygen valve first and then the fuel valve, if there is any issue with the fuel valve leaking, there will be a small flame left burning.
What is a rosebud torch tip used for?
Rosebud Heating Nozzle is used to quickly convert a torch from cutting to heating.
Why does my Rosebud torch keep popping?
If the velocity of gas flow outward through the tip is slower than the rate of burn of the gas, the flame will attempt to burn inside the tip. As the tip heats, more inner tip ignition of gases will occur. This will produce a banging or popping sound, and can lead to a flashback.
What is the hottest cutting torch?
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. However, this gas is the most expensive gas available and is not the most efficient for heating large areas.
What do you use to clean a torch tip?
Quote from the video:
Quote from Youtube video: So you got to come in with a tip cleaner you can get your local welding supply store.
What is backfiring in welding?
The momentary recession of the flame into the torch, potentially causng a flashback or sustained backfire. It is usually signaled by a popping sound, after which the flame may extinguish or reignite at the end of the tip.
What are the outside holes of a welding tip used for?
The six outer jets of a cutting tip are for oxygen and acetylene (Preheat Flames) and the central jet carries only oxygen. The preheat flames are not intended to melt the metal, but to bring it to its ignition temperature.
How do you clean welding tips?
Quote from the video:
Quote from Youtube video: As you can see it's it's tapered down to almost a point. You can also see that it has a lot of a lot of debris. That is collected on the cone. You can knock it. Off. You can you can take your pliers.
What is a Carburising flame?
A reducing oxyfuel gas flame in which there is an excess of fuel gas, resulting in a carbon rich zone extending around and beyond the cone. A carburizing flame is used in hardfacing and similar processes to obtain fusion between base metal and weld metal without deep melting of the base metal.
Why must oxygen working pressure be set with the oxygen cutting valve open?
Oxygen cylinders must have the valve opened up all the way because of the high pressure in the cylinder. There is a back-seating valve on the oxygen cylinder. This prevents the high-pressure gas from leaking out through the threaded stem.
