All Great counsel Bros. Im a Tac Tac Tac fan. I dont stay on the triger for more than 1.5 seconds and less than that with the real thin metal. I leave a gap between the patch and the patchee the width of the wire Im useing mostly .030 and place the wire in the gap and hit the trigger, then move away from that tac so it cools after the 1st couple tacs I break out my copper spoon.Some times if Im in a thin spot I keep my air gun handy and as soon as I tac I hit the tac with a burst of air. Id practice on some thin scrap 1st till you can get to know what it takes to make holes and adjust your technique. Good Luck
