Page 7: Precautions Of Electromagnetic Compatibility
Precautions of electromagnetic compatibility 1. Overview Welding brings electromagnetic interference. Minimize the interference emission of arc welding equipment with proper installation way and correct application method. The products described in the manual belong to Class A equipment (all occasions except residential area powered by public electrical power system). Warning: Class A equipment is not applicable to residential area powered by public electrical power system.
Page 8 3. Method of reducing radiation emission  Public power supply system The arc welding equipment shall be connected into public power supply system with the method recommended by the manufacturer. In case of interference, please take addition preventive measures, such as connecting filter with public power supply system.
Page 9: Main Technical Information
 Shielding The shielding of surrounding equipment and other cables can reduce the electromagnetic interference. The whole welding area can be shielded for special applications. Main technical information 1、 Main technical parameter Model MIG-270E Function Power Supply 220V±15% Voltage(V) Frequency(Hz) 50/60...

Page 21: Welding Machine Precautions And Maintenance
Welding machine precautions and maintenance 1. Safety points The welding machine is quipped with overcurrent and overheat protection circuits.When the gird voltage,output current and internal temperature exceed the set standard the welding machine will automatically stop working,but excessive use(such as excessive voltage) will still lead to welding,The machine is damaged,so you still need to pay attention to the following: ...
Page 22  Forbidden voltage too high! The power supply voltage is listed in the "main performance parameters" table. In general, the automatic voltage compensation circuit in the welding machine will ensure that the welding current remains within the allowable range. If the power supply voltage exceeds the allowable value, it will damage the welder.
Page 23 destruction of the internal components.  Check the internal contact areas to insure a tight connection (especially the plug-in joints or components) and reinforce the loose contact. If any rusting or oxidation occurs, use sandpaper to remove the oxide film and reconnect. ...
