The regulator on my TIG welder is making a fast, loud "clicking" noise. Purging didn't help. I've never heard anything like this before. The regulator is less than a year old and the tank is fairly new also. The gas line goes directly to the torch so it doesn't go through the machine unless MIG welding. Gas is controlled by a knob on the torch and power is controlled by a button on the torch. I wasn't using the pedal. I don't know if any of this additional information is helpful or not? It's a Tweeco 211i machine.
