    Default Did you mean...

    Did you mean the difference between A/C & D/C ??

    Are you stick welding or Tig welding?

    Default diff of ac or dc

    quite simply put the main diff is

    in stick current can affect the polarity of the workpiece and of the electrode, the heat that is distributed to the workpiece and the elecrode, the rate at which the electrode is deposited into the puddle, the depth of penetration and the occurance of arc blow.

    ac current reversal characteristics that effect the magnetic field are almost eliminated, as a result arc blow is not a problem in ac stick.

    in tig the diff of ac and dc is a little more technical, but simply put ac allows for ease of welding on lighter and non-ferrous materials. with a high-freq imposed on the current arc starts are much easier.

    ac machines produce higher voltages, allowing the use of larger electrodes thus increasing the rate of deposition. power consumption is lower making the ac machines more efficient.


    anyway I could go on and on but I hope this helped a little
