I've used my Oxford MigMaker 180-1 with E71-TGS flux core wire & polarity reversed & no shroud to get into awkward places on my old Convoy van.I have thought about buying a cheap gasless mig like the one from Dirty Pro Tools. I believe you can take the shroud off and have a large stick out as there's no gas shield to worry about. Anybody use a welder like this to get into awkward places?
