The acetylene regulator design is generally the same as that of the oxygen regulator, but will not withstand such high pressures. The high-pressure gauge, on the inlet side of the regulator, is graduated from 0 to 500 psi (3447.5 kPa). The high-pressure gauge indicates acetylene gas cylinder pressure.
What is a acetylene regulator used for?
Welding regulators are used to control and regulate the flow of high-pressure gases in a cylinder. Because various types of metals yield different rates of flow, finding the right welding regulator is necessary for control.
What should acetylene regulators be set at?
How do I set up the regulator? The acetylene regulator should be between 5-7 psi.
What should oxygen and acetylene regulators be set at?
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
Can you use a propane regulator for acetylene?
You WILL need to change your Acetylene Regulator to a Propane type (including for Propylene). You WILL need to change your Acetylene Hose to a Propane Hose (including for Propylene). You will need to check the label on your Flash Arrestor, if it says “Fuel”, it’s OK to use with Propane & Propylene.
What is the normal working pressure for acetylene?
The working pressure of acetylene equipment is critical: Acetylene pressure must not exceed 0.62 bar (9psi) unless equipment has been specifically designed for it.
Will an acetylene tank explode if shot?
The decomposition process may start during the heating of the acetylene cylinder and continue inside porous filler also after the outer surface of the cylinder is cooled down. If it happens, the cylinder becomes a time bomb that may explode much later.
Can I use an oxy acetylene torch with propane?
Oxy Propane/Propylene Torch
Whilst a standard Oxy Acetylene Torch can be used for Oxy Propane/Propylene, it’s far from ideal. Propane & Propylene are slower burning gases. Propane & Propylene also travel through the system as a vapour, not a gas, not actually turning into a gas until they meet air.
What regulator do I need for MIG welding?
Argon Regulators normally show Gas Flow Rate in Litres Per Minute and Cubic Feet Per Hour. It’s important to make sure the Delivery Gauge reads Flow Rate as most Mig and Tig Welders will quote a recommended delivery in Litres per Minute. An Argon Regulator should also be used for Argon/Co2 Mixed gases.
Why is my acetylene 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 do you set your oxygen and acetylene on?
The recommended setting for multi-hole cutting is the oxygen regulator at 40 PSIG, with the acetylene regulator setting at 10 PSIG.
What is the maximum pressure that acetylene must never exceed?
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. To do so is contrary to insurance regulations and is prohibited by law in many places.
What is the difference between propane and acetylene regulator?
Acetylene releases almost 40% of its heat in the inner flame cone. Therefore, acetylene is better for cutting than propane. While temperature wise acetylene is hotter than propane the fact is that people are using propane for cutting incorrectly.
Can I use LPG instead of 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.
What gas can replace acetylene?
Propane and other propane-based fuels are frequently used as substitutes for acetylene. In fact, many cutting operations are saving on fuel costs after switching over to propane. While propane doesn’t burn hot enough for welding, its outer cone offers a high number of BTUs.
