I figured out the spot welding function on the Dynasty 200 yesterday. I practiced welding stainless filler rods together end to end and Tee joints, this is the first time I have been able to do this with any degree of success!
200 amps for .1 second will butt weld 3/32" filler rods, the secret is to use as short a time as possible and high current settings.
I made several types of welds on various 308 filler rods with a high degree of success.
RMT2 hold, dc, .1 second 200 amps are the settings used, and I am sure I will improve over time.
I attached a couple of pictures...........
