The Multimatic 220 is
super easy to set up and use. It’s got Auto-Set technology that allows you to set it up automatically with your tungsten size
and also, all you do is just choose your material thickness and the machine will set
the parameters for you. They give you a range to use, but if you’re a control freak like I am, I’ll turn off the Auto-Set, and then I can adjust my
frequency and my balance just by pushing the buttons.
