Coolant flow test
If machine display coolant flow false alarm(060),shall refer to Coolant flow sensor maintenance and do one
maintenance.After done,if system still display coolant flow fault alarm,shall further check and find the cause of trouble
shooting.
8. Maintenance
Wearing parts life become short is the plasma system problem, the short life of spare will increase the cost.
