i haven't had any trouble at all. all the bottles i bought at auctions or picked up for free. we have three main suppliers in town here airgas, praxair, and kirk welding. all are chain stores and have found all to be very helpful and no troubles getting them filled. i tend to lean toward the one w/the cheaper prices but have found another to be more leanient in trading in bottles. if i get a new bottle if it is questionable or past it's date they can pressure test it or even change valve if it is old. then once you get one of their bottles thats marked sold you are in like flin. i even trade them in at other suppliers. just trade them in each time you go in. they always seem happy just to have me buying the gas. i have three of the big size bottles and you can't even buy those now you can only rent them. mine are marked sold so i just keep tradin em in. yep these are the real big rolls of wire they won't even fit in my 220 hobart, they are for like a seperate feeder and you want regular wire for carbon steel. i also got about 3000 lbs of arc rods at the same auction, that's a lot of rod! i also bought about 25 trailers (at the same auction)that need a little work so i will burn a few of em up. i was looking for that aluminum bodied ad but it wasn't there that day. yes very rare that's what i bought the aluminum wire for, when i find it all the customizing i will do. hr
