Just received my TIG200 and have a question on the power required. It came with a 3 prong plug that I assume is for 220. It has a adapter for use 110. If the three prong power plug is hot-hot-ground how does using a 110 plug that has a neutral feeding into the hot on the power plug work? There is no switch for changing from 110 to 220 that I can find. Also my wall receptical is a 4 pong 30amp 220 with hot-hot-neutral-ground. I can adapt to this but which do I eliminate the neutral or the groud? I assume that I would wire into the hot-hot-ground and not use the neutral. Is this right. I do not want to be feeding 220 into the machine if it does not have a automatic power switch somewhere inside the box. So confused.
