    Default Anyone experinced with a BOC 320r 3 phase mig?

    I have been offered a loan of BOC 320r (older Kemppi one) 3 phase mig while the owner is in Adelaide for a couple of months. It needs a few things doing to it (ie gears on the wire feed) to get it up and going, and I thought thats a fair trade to spend a little dough to have it at the factory for a while. I have some jobs coming up that require me making up some door frames (25mm tube 3mm) and some fiddly work with some 30mm tube (1.6mm). Fiddly for me, anyway. I'm an occasional welder that did a TAFE course 15 years ago.

    My concern is while I have been told it is a reliable machine and pretty stable I'm not sure if I want to invest time and money on it and get it going only to find it it doesn't weld 1.6mm any good. It looks a big machine, and I'm wondering if it is less than satisfactory with thinner steel. I don't know, and the owner hadn't used it for that so he wasn't much help.

    Anyone here with any experience with this machine and its performance and range?

    Perhaps contact this seller and ask -
    BOC 320 Amp MIG WELDER - GAS, GASLESS (440 volt, 3-PHASE) | Other Tools & DIY | Gumtree Australia Bunbury Area - Picton | 1021496078

    I haven't got any experience with this particular machine but having recently stick welded some 1.6mm tube frames I can say that it's as much about mindset, hand/eye coordination and joint quality as it is about machine setting. It sounds like the machine will do the job but you might need to do some practice first to get your eye in.

    OK.

    Well for anyone that has read this thread and might be interested in the answer, I went out and bought the bits and pieces this morning from BOC. My thought on the way to the factory was "What if I don't know the settings etc..". And the answer is.......

    Bloody great machine! Using 0.8mm wire I ran a bead on 2mm tube no probs, guessing the settings. Not great but easy to get going and obviously not much tweaking to get a good bead. The only other steel I has was a small piece 100mm x 100mm of polished steel only 0.6mm thick. No problems, no hole and smooth as you like. Yes, 0.6mm.
