Please help with the cable burner


I bought this cable burner, plugged into the power and it run but do not know how to attach the cables into and how long it takes for burning.

Could you please share your comments about how to use it. I, of course, am responsible for the usage myself.

Thank you very much.

Might be OK who knows but I have concerns about safety.
I would definitely want a cover for that thing.
Thank you very much for your recommendation. I hope to get some more opinions before plugging the cables.

@Rlwainwright: one single speaker cable has 4 connectors: red (No.1) to red (No. 2) and black (No.3) to black (No.4). Should I plug:

Red (No.1) to Red (of the burner);
Red (No.2) to Black (of the burner);
Black (No.3) to White;
Black (No.4) to Yellow?

I will have an technician metered the current and amps if possible.

Thank you again.
