I just bought one to use for a flat bed trailer (tractor trailer). Spent $230 on the kit. It is a little small and came with a 0 tip. Probably should have had a 1 or 2. Brought it at central tractor. It is a Hobart medium duty.

If you have never used a torch before, you are in for quite the learning curve. I burned thru the large tanks and still don't have a good feel for it.
