only bad thing I've got to say about this is. This little guy only runs on 220 volt power. It does not have the option to run on 110 volt power supply. But it comes with the standard 110 male plug. And without an adapter. I had to go purchase the adapter. Other than that. I use this machine as a100% duty cycle. And it holds up just fine. No over heating. No shut down and wait for it to cool off. It just keeps on going. 22 plus pounds of hard wire in one night
