Which turn off first oxygen or acetylene?
OXY-ACETYLENE We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel. This is only part, but a very important part, of the complete safe operating procedure recommended for torches by Harris.
How do you adjust the flame on a cutting torch?
What are the settings for oxygen and acetylene?
The recommended setting for multi-hole cutting is the oxygen regulator at 40 psig with the acetylene regulator setting at 10 psig.
How do you turn on a propane torch?
How to Light a Propane Torch Check the propane tank for leaks. Open the tank’s valve. Ignite the flame using the sparker supplied with your propane tank. Set the flame to the desired height and heat using the torch adjusting valve. Shut off the tank’s valve when you are done with your flame.
How do you extinguish the flame after gas welding?
How to extinguish the flame after use in gas welding? Shut off oxygen and dip blow pipe in water. Shut off oxygen and acetylene valve at a time. Shut off oxygen valve first next acetylene valve. Shut off acetylene valve first next oxygen valve.
How do you adjust a gas cutting 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 are the guidelines in adjusting the flame?
Adjust the flame by turning the collar to regulate air flow and produce an appropriate flame for the experiment (typically a medium blue flame). Do not leave open flames unattended and never leave the laboratory while the burner is on. Shut off gas when its use is complete. Allow the burner to cool before handling.
What should the pressure be set at for the oxygen?
For many reasons, patients that require additional oxygen use storage tanks with compressed oxygen to supplement their normal air intake. The size and subsequent capacity of the tank may vary but the full pressure is typically about 2,000 psi and can go as high as 3,000 psi.
What pressure should torches be set at?
NOTE: Most torch mixers use a “positive” design that requires fuel gas pressures set between 5-15 psi for cutting applications. However, some torches use an injector (low pressure) mixer design that only requires ¼ – 2 psi of alternate fuel gas.
Why isn’t my propane torch working?
Verify that your propane tank has enough fuel in it. If the tank is low on fuel, the torch won’t be able to pull out enough fuel to produce a strong flame. Refilling the propane tank will fix the problem.
Why does my torch not light?
If this does not work, the burner may be clogged; clean it with a blast of compressed air. If neither of these methods works, you may be low on butane or may have an air bubble in the lighter’s tank. The only way to definitively solve either problem is by emptying the lighter and refilling it with fresh butane.
What is the best way to light an oxyacetylene 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.
Where is the torch on my iPhone?
Use Control Centre on an iPhone with a Home button or an iPod touch Swipe up from the bottom edge of the screen to open Control Centre on your iPhone or iPod touch. Tap the Torch button . To turn off the torch, tap the Torch button. again.
How do I turn off the light on my iPhone?
You can turn off your iPhone flashlight with a swipe to the phone’s Control Center and a tap of the flashlight button. With even less effort, you can also turn off an iPhone’s flashlight by swiping partially or fully left onto the Camera app from your iPhone’s lock screen.
How do I turn on the torch on my Samsung?

Which is the method to control back fire while welding?
A flashback arrestor or flash arrestor is a gas safety device most commonly used in oxy-fuel welding and cutting to stop the flame or reverse flow of gas back up into the equipment or supply line. It protects the user and equipment from damage or explosions.
How do you prevent backfire in welding?
There are several things you can do to help prevent flashbacks, fires and explosions: If using acetylene, keep the pressure below 15 pounds. Purge your hoses before lighting the torch. Never light your torch with a mixture of fuel and oxygen. Check valves should be installed on both torch inlets and operating properly.
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.
What is the ratio of oxygen and acetylene in gas cutting?
1.2:1 Table : Fuel Gas Characteristics Fuel Gas Maximum Flame Temperature °C Oxygen to fuel gas Ratio (vol) Acetylene 3,160 1.2:1 Propane 2,828 4.3:1 MAPP 2,976 3.3:1.
What is the best way to set the oxygen pressure for cutting?
25. What is the best way to set the oxygen pressure for cutting? Increase the pressure slowly and readjust the flame as you watch the length of the clear cutting stream in the center of the flame.
What gauge pressure should acetylene never be set above?
Never use acetylene at pressures above 15 psi. Using acetylene at pressures in excess of 15 psi gauge pressure (or about 30 psi absolute pressure) is a hazardous practice.
