Reply:There is a relay that opens and allows the argon to flow when pedal is pressed. Could that be what you are hearing? Sent from my iPhone using Tapatalk

Reply:Yes, you should hear gas when you push the peddle for 15 - 20 seconds.  If you continue to hear it something is wrong.  Push the peddle slightly more and you will hear the buzzing of the HF but it should stop as soon as the peddle is released.
