Thread: Welder myth

  1. #1

    Question Welder myth

    Well this isn't a miller question but I was wondering about it, From what I know there has been a lot of stir about the stick lincoln buzz boxes have changed to aluminum coils instead of copper like in the old ones? Does anyone know the real story behind this? Thanks

    maybe this answers my question "why is the new MM212 23 lbs lighter than the MM210 was?". I also just checked the spec on the MM252 compared to the MM251 and there is a 21 lb difference there as well. This seems like a big difference to me. If it is aluminum I hope it holds up better than the old aluminum house wiring!

    i think the problem with the old house wire was the connection points where aluminum and copper connected. they expand at different rates with heat, that caused the connections to loosen over time. that caused lots of fires from loose connections.
    i'm shore the coper and aluminum cores have similar performance ratings. saving a few $$ on aluminum over copper would be a bad call if its caused a problem with the welders. i'm shore they have been well tested. the lbs change would seem proof the cores have been changed to aluminum.

    The alu or copper debate pops up from time to time. Either will work and the machines have been optimized to work with whatever they have inside. It really isn't a big issue with the crackerboxes. Get up to a bigger generator and the differences become a little more apparent. Myself, I would like a lighter machine. I had to pull my T'bolt out from under my table the other day. That was not very fun. I don't move that one very often and was quickly reminded how heavy it really is.

    DDA52, would you worry if your mm210 had an Alu secondary coil on the transformer? This is how the new mm212 is set up, hence the weight difference of 23 lbs. As you say in your last post, they are set and tested to work with what they have, and they carry the same warrenty. In my mind copper would be better. But I already have a new mm212 still bolted to the pallet in my shop, waiting for my new Bernard gun to arrive.
