By completing welds quicker, MFDC welding prevents much of the heat deformation and spatter typically associated with AC welding. The fact that the peak voltage of an MFDC weld is almost the same as RMS voltage further contributes to a reduction in sparks and spatter that are a given with AC welding.
Since welds can be completed in 0,001 second as opposed to 0,020 of a second, as well as less pressure being exerted during the weld, there is less damage caused to the metal pieces being joined by MFDC welds than to ones joined by AC welds. This allows for a superior level of structural integrity in the final product, enhancing its overall durability and useful life. Beyond the structural superiority of an MFDC weld, the “weld nuggets” left behind by MFDC welding are typically smaller and smoother than the ones left by AC welding. This makes the final product safer to handle by hand, as reduces the amount of sharp edges left after the welding is done. In products that have to be clear of burrs and other sharp edges, this can massively reduce the time spent on getting parts ready to ship, as there will be fewer sharps to clean up
