If there are special circumstances, be careful not to connect the power supply. \x0d\ 36。 When replacing the contactor in the cabinet in the production process, it is necessary to check whether the power supply line can be disconnected, and it is strictly forbidden to replace it with electricity to prevent danger. \x0d\ 37。 In production, it is not allowed to press down the pressure roller due to the maintenance of the air valve, which will cause the steel strip to deviate or break. \x0d\ 38。 It is not allowed to weld the circuit board with voltage sensitive components. Unplug the power plug after the soldering iron is heated before welding or the welding head is grounded. Before removing the electronic board, human static electricity must be discharged. \x0d\ 40。 When using electric welding machine, it is not allowed to use production line frame as ground wire to prevent burning out PLC. Anyone who breaks the rules will be stopped immediately. \x0d\ 4 1。 When using electric welding machine, insulating gloves should be worn, and it is not allowed to hold the electrode holder in one hand and the grounding wire in the other to prevent accidental electric shock. \x0d\42。 When welding equipment with bearings and bushings, it is forbidden to make the welding current pass through the bearings and bushings, causing damage. \x0d\ 43。 When hot work is carried out in the substation room, the application procedures for hot work must be fulfilled, and hot work is strictly prohibited without going through the formalities. \x0d\ 44。 Don't fasten the buttons or indicator lights on the console during production.
