Gave my son my welder. He has a new plasma cutter. So this one is for sale. I have owned it for over 20 years. It is a Thermal Dynamics econo pack 50. It has a Wilkerson dual add on air filtration unit. I have extra tips and electrodes. You need an air compressor and 220 volt to use it. If interested let’s chat. The cart does not go with it. Thanks
