Check the two main diodes. These units have a light duty cycle. About 20% if I remember correctly. I have one that I was welding with for a considerable amount of time, and burned up the diodes. You can test them by disconnecting the wires (with unit disconnected) and use a ohm meter. You should get a reading in one direction, but not the other. If no reading, then the diode is blown. You can order new ones from your local welding shop. Also check all conections on the secondary for any signs of overheating and loose connections.
