I have recentlt purchased a diversion 180 and love it so far. My question is it seems once I shut my bottle off when done useing a day or two later it has bleed down to zero. I have already soaped everything from bottle to the back of welder where the line goes in and found nothing. I dont feel as only being a couple months old I should have to open it up to look for a leak nor do i want to void my warranty. I would think if i had a leak at my torch obviousely it must be going through the machine first no????? love the machine a little irritated at this situation though as we all know the argon does not come cheap, any input would be great thanks, Eric
