The gauges that are located on the oxyacetylene torch measure _____________________________________.

The gauges on an oxyacetylene torch serve two crucial functions: they measure the tank pressure and the regulated pressure supplied to the torch tip. The tank pressure gauge indicates the pressure of the gas within the cylinder, which is essential for monitoring the amount of gas available and ensuring safety during operation. The second gauge, known as the working or regulated pressure gauge, shows the pressure at which the gases are being delivered to the torch for combustion.

This two-gauge system allows the user to adjust the output pressure to achieve the desired flame characteristics for specific welding or cutting tasks. Proper understanding and use of these pressures are vital for effective and safe operation of the oxyacetylene torch. Having accurate readings of both pressures ensures that the operator can work efficiently while minimizing risks related to over-pressurization or inadequate flame characteristics.
