The hardware on this thing sucks. I just drilled my own holes and used my own screws. Once you do that, this rack is pretty cool and really solid. I have an 80cu and Hobart 210 bottle and I'm not concerned about that at all. But it's very disappointing that Hobart supplies this with the cheapest of cheap Chinese lights that come loose halfway through installation. I would give this thing five stars but I literally had to drill holes for all the screws and was expecting a lot more. from Hobart.
