I have a Uniworld UPM-20E commercial mixer. I bought used from another baker and it was working when I bought it.

Electric devices get damaged sometimes by internal corrosion even if you don't use them. If you have the technical knowledge, take apart the control board or control panel, probably you've got some contact problem. you might be able repair it by cleaning or maybe you might need some part to replace.
If you don't have real knowledge repairing this kind of an appliance, my best advice: take it to a repair service.
Some time ago I tried to do a similar job with my home mixer and had to take pieces in a shoebox to a repair service ; I took it apart, cleaned contacts bur couldn't assemble it againbecause after taking it apat, couldn't assemble it again

I have a Kitchenaid Artisan 5qt stand mixer that sparks and kicks the breaker when switched on. I removed the ground. Now, it comes on when plugged in, even when the switch is in the off position.

Please unplug it and leave it alone. The earth wire is a life saving device put there to stop you killing yourself if something goes wrong. It is not a little green wire that you can remove on a whim even if just for testing purposes. Your mixer is unsafe if plugged in without it.
The fault is unlikely to be a big deal as far as expense goes, a proper service agent will be able to locate the fault using their eyes and a multi meter. I would be looking for broken or partly detached wiring inside, maybe even insulation worn through somewhere.
Phone Kitchen Aid and ask who your local service agent is.

By the time you get these, postage and shipping etc, you may as well buy a cheaper handmixer.

Broken wire - Kenwood A701A

black wire indicates negative so if you can see a place on the circuit board that looks like that's were it came from then get some advice from an electronics person before you put it together.

My kitchenaid mixer run on high at all times

If your mixer only runs on high speed there are 3 things that can cause that. The first thing to check will be the speed control plate, Remove the trim and end cover on the mixer, the first thing you should see is the speed control plate, this has 3 screws on it, try adjusting the top two screws 1/4 turn, this should slow the mixer down, do not over tighten. Also check to see if the control plate spring is unhooked. If the spring is unhooked, attach to bottom of the control plate, and squeeze the spring end.
If this does not fix your mixer, check the wiring of the mixer, you can locate a wiring diagram on the last page of the service manual.
If the speed control plate is adjusted correctly and all the wiring is correct it will be your speed control phase board. You can test the speed control phase board to see if it is shorted. With the line cord disconnected, pull the t-b ar contacts to open, and insert a piece of paper between them so they cannot close. Reapply power-the mixer should just run or buzz trying to run. If it operates at full speed, teh phase control board is defective and needs to be replaced.
Here is a link to the service manual:
This will aid you in taking the mixer apart, troubleshooting and putting it back together, remember the wiring diagram is the very last page.
Thank you,
Customer Service

Missing the bowl raising handle

Check your manual that came with it. There's usually a customer service number. Things like that usually must be ordered dirctly from the manufacturer.

Electric current

The three pronged wire contains a green wire which is connected to the metal housing of the mixer. It sounds like either that wire is broken, or disconnected inside the mixer, or the service into which you are plugging the mixer does not have a ground wire connected to a proper ground.

Remove the rear cover and look for a green wire and make sure it is connected to the metal of the frame.

If it is then check the outlet you are using to ensure it is wired correctly.
