Mark, I'm sorry but I have no info or experience on the 3200. It may be a newer model. Mine is the 100. The upgrade could be worth it, especially if the 3200 included a gas control solenoid so you could use a shielding gas. The 100 will control an accessory solenoid valve so you can use gas.

This is important if you intend to ever weld aluminum or stainless. I have managed to successfully weld cast alluminum with flux coated rods but I credit much of the results to DUMB LUCK!
