An arc system is described which includes a power generator, a shielding gas source, a torch and a shielding gas monitor contained adjacent to or within the torch. The torch is connected to the power generator for producing an arc with a workpiece, is connected to the shielding gas source for providing shielding gas to an arc locations, and includes a flow sensor mounted within or adjacent the torch body for monitoring the flow of shielding gas through the torch and optimally providing feedback control of the shielding gas flow.
