I was looking for a small arc welder to replace my Chicago Electric 80 amp inverter arc welder, that after 8 or nine years of light use, was losing its ability to consistently start and hold a burn. I saw some reviews on YouTube of the Vevor MMA 200 and ordered one from Vevor. Not only was it on sale ( as of 3/24), for less than a $100.00, but the shipping was free and it arrived in about a week! And.the welder runs on 120v and 220v and has worked very nicely!
