The acetylene gas cutting torch and gas pressure regulator are two key tools of the welding trade. Taking proper care and caution when using these two tools will go a long way toward ensuring a safe welding environment.
Gas Pressure Regulators
Regulators reduce the flow of gas from a supply tank to a level that is safe to use. These devices usually consist of a gauge measuring the pressure level in the gas cylinder, and another gauge measuring the pressure of gas flowing through the hose.
Before using a regulator, it’s extremely important to make sure the device meets all of the necessary requirements for use in oxy-fuel cutting operations. The gas pressure regulator should also be kept in good condition, inspected before each use and repaired when needed only by a properly trained professional.
Safety precautions for using gas regulators
? Always be sure to close the regulator valve before opening the valve to the gas cylinder. Check the manufacturer’s guide if you have any uncertainty concerning the open and close positions of the regulator valve.
? Using a wrench of the correct size is important when connecting regulators to gas cylinders. Prevent causing damage to the regulator by avoiding a forced connection.
? Avoid high pressure gas surges from regulators by slowly opening the cylinder valve. When doing this, make sure to stand to the side of the regulator, not in front or behind. A gas pressure gauge
? If a leak is suspected, immediately turn off all equipment. Once all equipment is shut down, proceed to check for leaks using a regulatory agency-approved detection method.
Welding Torch
When it comes to torch safety, it is important to use the proper equipment, check for leaks at connection points and purging hoses before igniting the flame. Keeping the torch in top condition is also essential in order to avoid hazardous situations where leaks might occur.
