Hello MetalFinagler, you really need to check on the proper orientation of the ground lug on the plug you are using to be sure that you have the ground wire(green) hooked up to the appropriate blade, I don't believe you do from your description. You have tucked back the correct wire for single phase use, however you may have hooked up one leg of the 220 to the ground wire to your machine which could pose a severe shock hazard to you and possibly damage your machine. Green is ground, black is a 110volt leg in 220volt single-phase operation and white is another 110volt leg in 220volt single-phase operation. BE VERY SURE of the proper connections on the plug that you are using and verify with a volt meter before trying to use your machine further. If possible get ahold of an electrician or other qualified electrical technician to help you with properly hooking up your machine. Best regards, Allan
