   7.2.3  Prevent over-voltage

 

 

      The welding voltage within the circuit will automatically compensate to ensure 

 

 

      the welding current is in the permitted range. If the voltage exceeds the 

 

 

      allowable value it can damage the machine. The welder should be fully aware of 

 

 

      this and take appropriate preventive measures.

8 MAINTENANCE

 

The following operations require the welder has sufficient electrical expertise and can

 

demonstrate a comprehensive knowledge of working safely with valid qualifications and 

 

documents. Check to make sure the welding power input cable is not broken.

 

8.1  Periodically inspect the internal circuit connections are intact and reliable (especially 

 

 

the joints or components). If any rust and debris is found, sand off, clean, reconnect

 

 

and tighten.

 

8.2  Do not allow hands, hair and tools near live components or fans inside the machine. 

 

8.3  Regularly clean machine with dry compressed air. Compressed air pressure should be 

 

 

at a reasonable level in order to avoid damage to the welding of small internal

 

 

components. Dust the machine regurlarly.

 

8.4  Avoid water or water vapour getting inside the welding machine inside. In the event of

 

 

accidental ingress, the machine should be thoroughly dried. Only when you are sure 

 

 

that any moisture or water has been thoroughly dried from inside may you use the 

 

 

machine. Suitable tools for checking the moisture content within are advised.

 

8.5  Regularly inspect the cable insulation for damage. In the event of any damage wrap or 

 

 

replace the cable.

 

8.6  When not using the machine, place back in the case and keep in a dry environment.
