I only have pre flow gas then shuts off

I have a 200dx. What am I doing wrong that the gas stops flowing after the pre flow? I have it set up to use the pedal and when I depress the pedal gas flows then the arc initiates for a split second until the gas stops. Thank you.

Please list all of your settings. If you just tap the pedal, does gas flow for the post flow time?

Thank you for the reply. I think it was the regulator. I tapped on it a few times, opened it/closed it and now its working.
