I woke up my old Lincoln TIG 300-300 today after a long sleep. This is one of the old gray beasts circa 1976. The argon valve doesn't open every time the arc is started. If it's still open on the post flow timer, it stays open when welding, but when I first press the amptrol, it might take 4 or 5 hits before it opens, which is really annoying at best. Is this likely just a sticky valve, or is it electrical?
