Remember, an arc needs voltage to form (as in "jump across the gap"), not current. Current only comes into play once the plasma arc is formed.

Having no experience with TIG I really can't answer the question directly, but I hope what I wrote helps.

It does help, as you brought up a good point. Thanks!

I had originally suspected such a problem, and was told over and over by peers that the gun was getting gas. I'm not so sure if they know what they are talking about, since I can't hear the afterflow. I thought it may have just been a quiet gun Stupid me...

I had ground the tungsten to a sharp point, but isn't the tip supposed to ball up while welding aluminum?
