I bought this to run my iron worker because I didn’t have 3 phase electric. My shops single phase . The directions are decent. I wish someone would make a video on how to adjust the settings that’s the only confusing part . I need 60HZ but my machine is working on the factory 50hz setting so for now that’s where it’s gonna stay. I had to bypass the factory control board & wire it directly to the motor. Works great so far . A YouTube video on this would be a lot of help but I couldn’t find one for my application. I am happy with it :). Josh. Wed Feb 15 2023
