Welding for the first time - need advice

I got out there today to practice again and I just don't think the gas is working.

When I turn the gas on the gauge on the left reads 25 CFH. I pull the trigger and it momentarily drops to 22-23 and then back to 25 as soon as I let go.

I disconnected the wire feed and put my ear up to the gas nozzle and I don't hear anything. I also used the lighter trick and the flame never went out or even blew around. It seems like I'm not getting any gas at all even though the gauge acts like I am.

I wasn't hearing the solenoid like you guys were talking about so I reversed the polarity of the wires and pulled the trigger again and got the same sound, so I don't even think the solenoid is working at all.

I'll try calling Hobart but I've had the thing for 3 1/2 years so I doubt they'll be of any help.
