Operational specifications that should be paid special attention to in the daily operation of high-frequency quenching equipment:

(1) There must be more than two people to operate the high-frequency equipment, and the person in charge of the operation should be designated, and the insulating shoes, insulating gloves and other prescribed protective equipment should be worn.

(2) The operator must be familiar with the operating procedures of the high-frequency equipment, and should check whether the cooling system of the equipment is normal before starting the machine.

(3) All doors should be closed before work, and electrical interlocking devices should be installed on the doors to ensure that electricity cannot be sent before the doors are closed. After the high voltage is closed, do not move to the back of the machine at will, and it is strictly forbidden to open the door.

(4) Burrs, iron filings and oil stains should be removed from the workpiece, otherwise it is easy to cause arcing with the sensor during heating. The arc light generated by the arc can not only damage the eyesight, but also easily break the sensor and damage the equipment.

(5) High-frequency equipment should be kept clean, dry and dust-free. If abnormal phenomena are found during work, the high-voltage power should be cut off first, and then checked and eliminated. There must be a special person to overhaul the high-frequency equipment. After opening the door, first discharge the anode, grid, capacitor, etc. with an electric rod, and then start the overhaul.

(6) When using quenching machine tools, safety regulations concerning electrical, mechanical and hydraulic transmission should be observed. When moving the quenching machine, it should be prevented from tipping.
