Why do I need 2 people on site to repair an induction melting furnace?

Because the current tonnage and power of fatana mitsonika induction have further increased, the risks and dangers have also increased. Electrical maintenance workers who have not received on-the-job training cannot repair the induction melting furnace electrical appliances, because during the repair process, the maintenance personnel are killed by electric shock or arc burns from time to time. There must be more than 2 people on site during maintenance.
