Another thing I've dealt with, other than getting the settings on the welder correct, is that the flow of gas can be interrupted by misalignment where the gun tube plugs into the machine. Have developed the habit of always listening for gas when I test trigger the gun, every time I turn it on. 
Have also found that the suggested settings on mine (millermatic 250) are pretty conservative- I tend to set the voltage a bit higher than the decal says to.
