Dual shield WOW

    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.

    Requires a lot less voltage than solid wire as the resistance is a lot less.

    The filled core is also electrically conductive.

    Deposition is higher, as burn off rate is so much higher.

    Gas tracks are from excess voltage or too short a contact tip to work distance. CTTWD should be 15-25mm

    Get your setting dialed in and other parameters good, ie gas flow rates and as Brad mentiine above stickout length, and theyre definitely the way forward for thick sections i think.
    Took a bit of getting used to though imho, one thing being the speed of it, especially positionally.
    Dont do a lot of fluxcore really where i working now.... most of the heavier stuff is stick welded with iron powders, or low hy's. The firm is only just making its way out of the dark ages lol
