I am newly registered to this site, but had checked it out when trying to decide which tig to buy. I decided on a dynasty 200 dx over the lincoln invertec 200. I received my new welder on thursday and with a long weekend figured I would start getting used to the new machine. I got everything set up double checked everything plugged it in and nothing happened. After about 20 seconds smoke started slowly rolling out of the case and I heard a loud pop, turned off the machine killed the breaker and unplugged it. So much for using over the weekend.
