A method and system for detecting a welding gas leak is provided. One welding power supply includes a gas valve configured to control the flow of shielding gas to a welding device through a gas line. The welding power supply also includes a sensor coupled to the gas line and configured to detect a parameter of the shielding gas. The welding power supply includes control circuitry coupled to the gas valve and to the sensor, and configured to control the operation of the gas valve, and to receive device value representative of the detected parameter. The control circuitry is further configured to determine a leak test result based upon the parameter value, and to provide an operator indicator of the leak test result.
