A device on an oxyacetylene rig that controls the flow of gas is called a

Gauge
Regulator
Valve
Vent

The correct answer is: Regulator

A regulator is the correct answer because it is a device used in oxyacetylene rigs to control the flow of gas. Regulators ensure that the gas is delivered at a consistent pressure to the torch for proper combustion and welding processes. While gauges are also part of the oxyacetylene rig and display the pressure of the gases, they do not control the flow of gas. Valves are used to open and close the gas flow but do not regulate the pressure. Vents are used to release excess gas safely but do not control the flow or pressure of the gas.
