Gas Not Getting To Nozzle

[EdK]

I got all set up to practice some welding and decided I better test for gas flow. I tried listening for the gas hiss but didn't hear any. I assumed it was because of the welder noise so I got a candle and lit it and aimed the nozzle at the flame and it didn't move a hair. So definitely no gas getting out of the nozzle. No wonder the welds I had tried when I first got the gas were full of porosity.
I had set the flow to 20 while I had the trigger engaged and it would go up a bit when I released the trigger so I know there is gas getting into the welder. I'm stumped as to where to look next.

Any help would be appreciated.
