I'm fairly new to TIG welding. I have a Dynasty 200 that I bought a month ago along with the Miller Contractor's package with foot pedal control. When I got the welder I also got a 125 cu ft Argon cylinder. Almost all of my welding to date has been with a 1/16" electrode and a #5 cup. I've set the flow control to the recommended 15 cu ft /hour.
I was surprised by the rate at which the Argon is disappearing so I checked the hidden menu for total arc time and number of arc starts. Total arc time is a tick over 3 hours and number of arc starts was 720. (OK, so I'm not very good yet!) I'm using the "auto" setting for post flow. I calculate that accounting for post flow time for all those arc starts plus the total arc time I should have used 60 to 70 cu ft of argon but I've used substantially more than that.
Is it possible that the flow control gauge set is giving me more flow than is indicated? I'm using the gauge set supplied by Miller in the Contractor's package.
