Its the base for 3 small cabins that will be shipped to a mining town.. The structure is built from 200x100x4.0mm (8" x 4") RHS.. 4 stiffeners running between the two main bearers.. and 31 floor joists made from 150mm x 1.5mm galvanized C-Section..
I did the whole thing with the Bobcat and 12VS wirefeeder.. 5kg's (11pounds) of wire.. About 10 hours solid welding.
Its the first really serious workout I've given the 12VS.. I was very happy with it! I hope the customer was happy to.. its a prototype for another 390 he wants to build!
