3. FASTMIG ERROR CODES
The existence of possible faults in the equipment is investigated in connection with each
wire feed unit start-up. If a fault is detected, the fault in question will be indicated as an ’Err’
message on the panel display.
Error code examples:
Err 2: Undervoltage
The device has stopped because it has detected a mains undervoltage that disturbs welding.
Check the quality of the supply network.
Err 3: Overvoltage
The device has stopped because dangerously high temporary voltage surges or a continuous
over-voltage has been detected in the electric network. Check the quality of the supply
network.
Err 4: Power source is overheated
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.
Err 5: 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.
Err 54: No data communication from power source
The data transmission between the power source and the wire feed unit has been cut off or is
defective. Check the extension lead and connections.
Err 55: Power source is busy
The communication channel is busy. The power source is being used by another wire feed unit
or the programming for some other device in the channel (e.g. control panel) is in progress.
Err 61: The water unit is not found
Water unit is not connected to the equipment or there is a connection fault.
Connect up the water unit or change the setting of the unit to air-cooled, if you are using a
air-cooled welding gun
Err 153: Overheating of liquid-cooled PMT gun
When starting to weld or during welding, the overheat protection on the liquid-cooled MIG
welding gun has activated. Check that there is sufficient liquid in the cooling unit and that
air is circulating freely through it. Ensure that liquid is circulating freely through the cooling
hoses.
Err 154: Overloading of the wire feed motor
The welding has been interrupted because the loading of the wire feed motor has risen to
a high level. The cause of this could be a blockage of the wire line. Check the wire conduit,
contact tip and feed rolls.
Err 155: Warning of the wire feed unit overloading
The wire feed motor load level has risen. The cause could be dirty wire conduits or a gun cable
twisted into sharp curves. Check the state of the gun and clean the wire line if necessary
Err 165: Gas guard alarm
Gas guard function has worked, because the pressure of gas has decreased. Possibly reasons:
Gas is unconnected to the wire feeder. Gas has been ran out, gas hose is leaking or there is no
pressure enough in the gas web. Connect the gas to the wire feeder, check gas hose and the
pressure of the gas web.
