We have received a large resupply of Mosfet units and parts for warranty replacement. In fact, we have a large surplus. These units have been thoroughly prepared and inspected in our new factory. We are offering extreme discounts to anyone interested in a lightweight welder, multifunction combo unit or plasma cutter. Since we will not be carrying these units long term, except for a warranty stock, there may be some differences in warranty length, but the price will reflect it too. Discuss it with sales when you call.
