    Setting pulse functions can be all sorts of fun. I just took a quick look at the manual for that machine.

    50/50 on spot welding... those materials might not play well together.
    Silver brazing might be your best bet. With induction heating and good fixturing it would be easy enough.

    If you didnt need a hand held unit, I know miller makes a nice spot welder. I cant remember the numbers and I dont work at that shop anymore, but I can find out what it was.

    I've done a bunch of cast iron repairs and the best I've found is welding it with oxy fuel. They make square filler rods and cans of flux that you have to dip the rods in. Its an older method but it...
