4.4 missing pHAse in tHe eleCtriC netWOrK
If a phase is missing from the mains current, the welding features will be adversely affected or
the machine may have problems starting. Loss of a phase can be caused by a:
• Blown mains fuse
• Damaged mains cable
• Poor mains cable connection in the machine’s terminal block or mains socket
4.5 errOr CODes
The machine always checks its operation automatically during start-up and reports any
failures detected. If failures are detected during start-up, they are shown as error codes on the
control panel display.
err3: power source overvoltage
The machine has stopped the welding because it has detected momentary voltage spikes or
continuous overvoltage dangerous to the machine in the electric network. Check the quality
of the supply network.
err4: power source overheating
The power source has overheated. The cause may be one of the following:
• The power source has been used for a long time at maximum power.
• The circulation of cooling air to the power source is blocked.
• The cooling system has experienced a failure.
Remove any obstacle to air circulation, and wait until the power source fan has cooled down
the machine.
err5 Water unit alarm
The water circulation is blocked. The cause may be one of the following:
• Congestion or disconnection in the cooling pipeline
• Insufficient cooling liquid
• Excessive cooling liquid temperature
Check the circulation of the cooling liquid and the air circulation of the water unit.
err23: power source overvoltage warning
The power source has detected voltage spikes in the electric network. Short power spikes
can be managed. They do not lead to interruptions in welding but may decrease the welding
quality. Check the quality of the supply network.
err61: the water unit is not found
The water unit is not connected to the equipment, or the connection has failed. Connector the
water unit.
Other error codes:
If an error code not listed above is shown, contact Kemppi service and tell them the error
code.
