Da Bomb
This gas uses left-handed threads for safety.
What is Acetylene?
This gas is commonly used with oxygen in oxy-fuel cutting because it produces a very hot flame.
What is acetylene?
The temperature at which rapid oxidation (combustion) can begin.
What is Kindling Temperature?
This flame type has equal oxygen and acetylene and is most commonly used for cutting steel.
What is a Neutral Flame?
If acetylene pressure exceeds above this PSI, the gas becomes unstable and can explode.
What is 15 psi?
This gas supports combustion and is required for oxy-fuel cutting and welding.
What is oxygen?
This part of the torch mixes oxygen and fuel gas before combustion.
What is the mixing chamber?
When making a cut, this is the distance the inner cones of the flame should be kept (1/8in.-3/8in.) from the surface of the plate.
What is Coupling distance or work distance?
This is what occurs when a flame goes out with a loud snap or pop.
What is a Backfire?
To make sure we are not leaking gas, we must make sure these are turned off on the torch before pressurizing the lines.
What is torch valves?
This device reduces the high pressure from a gas cylinder to a usable pressure.
What is a regulator?
This flame type has excess acetylene and produces a feathery inner cone.
What is a carburizing (reducing) flame?
This zone is the portion of the base metal whose mechanical properties are altered by the heat of cutting.
What is the Heat-affected zone?
This process uses oxygen to rapidly oxidize metal to cut through steel.
What is oxy-fuel cutting?
This is the shade number we use for cutting.
What is Shade 5?
This chemical compound is placed inside acetylene cylinders to stabilize the gas.
Answer: What is acetone?
This flame type has excess oxygen and makes a loud hissing sound.
What is an oxidizing flame?
The space left in the work piece as the metal is removed during a cut.
What is Kerf?
This principle explains how cutting works when oxygen reacts with hot steel.
What is rapid oxidation (exothermic reaction)?
Before attaching a regulator, you briefly open the cylinder valve to do this.
What is crack the valve?
Oxygen cylinders are filled to about this pressure when full (typical industrial value).
What is around 2,200 psi?
This temperature is approximately the maximum flame temperature of an oxy-acetylene flame in °F.
What is about 6,300°F?
Two different types of this are produced during a cut, one is easier to remove than the other.
What is Slag? (hard or soft)
This zone of the oxy-acetylene flame contains the highest temperature.
What is the tip of the inner cone?
This safety device prevents flame from traveling back into the hose or cylinder.
What is a flashback arrestor?
