Abstract
A pressure sensor is arranged to sense the pressure of a pressurized welding gas and produce a variable control output dependent upon the pressure level sensed. A control signal is initiated in response to pressure of a predetermined level being sensed, the control signal being passed to the welding apparatus driver circuitry to inhibit the welding operation.
