MAINTENANCE
CAUTION
：
Before maintenance or opening the machine power must be turned off, and the power cable should
be unplugged from the wall.
Remove dust and debris with dry and clean compressed air regularly. If the machine is operating in
an environment where it is polluted with smoke and dirty air the machine will need dust removed
daily.
Pressure of compressed air must be inside a reasonable range in order to prevent damage to internal
components of the machine.
Check internal connections regularly and make sure the connectors are connected tightly. If scale
and loose connections are found, please clean them and then connect them again tightly.
Prevent water and steam from entering into the machine, if they enter into the machine the internals
need thoroughly dried before use.
If the welding machine will not be operated for long periods of time, it must be stored in a clean dry
area.
