I thought it sounded weird too, Phil, and we discussed it. He was using copper coated wire, and tried new rolls. As new it worked fine, but after leaving it standing for a couple of weeks while he was on leave, he said it gave him trouble. He didn't say how long it took to fix it, or how many times he's experienced it.
It might just be something peculiar to his handpiece too, so not saying its a fault with all gasless MIGs - just something to keep in mind.
