I agree that the LOTOS looks inferior. I'm trying to find a machine that has roughly the same claimed capabilities.
OK, how are you getting to the PowerTIG components?
I clicked PRODUCTS, then selected Multi Process:
From the Multi Process screen, I clicked MULTIPROCESS WELDER UNITS.
However, the Multi Purpose Units page that pulls up does not show a PowerTIG. I only see PowerUltra and PowerPro models, and nothing with the 200 DX designation.
