MAINTENANCE
1.
Remove dust by dry and clean compressed air regularly, if welding machine is operating in
environment where is polluted with smokes and pollution air, the machine needs to be cleaned once
a month.
2.
Pressure of compressed air must be within the reasonable range in order to prevent damaging to
small components of inner-machine.
3.
Check internal circuit of welding machine regularly and make sure the circuit connections are
connected correctly and tightly (especially plug-in connector and components). If scale and rust are
found, please clean it, and connect again tightly.
4.
Prevent water and steam from entering into the machine. If that happens, please blow it dry and
check insulation of machine.
5.
If welding machine will not be used for long time, it must be put into the packing box and stored in
dry and clean environment.
WARNING
！
Connected welding machine to dynamotor directly will damage machine. The heavy
voltage pulse which is produced by dynamotor will burn out machine when machine
connected to dynamotor, only can use asynchronous dynamotor whose frequency
and voltage both are steady. Because of connecting welding machine to dynamotor
directly lead to damage and malfunction, which is not in guarantee.
