I bought a roll of 1.2mm dual shield Bohler Ti52 wire and had a project today where it could be pretty good. Had to weld a bunch of 10mm plates to other 10mm plates that had holes drilled/tapped for some large casters. I put a chamfer on the upright plates and the stengthening/webbing plates. After seeing my Binzel 401 uses M8 threaded tips I had to buy some M8/1.2mm tips I set about welding the plates. Has some massive wormtracks in the welds, but also the arc was WAY hot. Turned the welder down quite a bit and the stuff welds beautifully, with great penetration. The slag just peels of For anybody thinking about starting to use dual shield I would advise giving it a try , but I would also advise in some method of fume extraction as well.
