Page 3: Read This First
READ THIS FIRST Maintenance and repair work should be performed by an experienced person, and electrical work only by a trained electrician. Use only recommended replacement parts. This service manual is intended for use by technicians with electrical/electronic training for help in connection with fault--tracing and repair. -
Page 4: Description Of Operation
DESCRIPTION OF OPERATION 1AP1 Welding data board The hardware of the printed circuit board is the same for the MA4, MA6 and U6 panels. For the M2 panel the same board is used, but there are some differences in the hardware. Circuit board identity The welding data board has a machine ID, a hardware ID and a unit type number. -
Page 5: 1Ap1:2 Communication
1AP1:2 Communication Communication between the control panel and the machine is via the system’s CAN bus. Resistor R3 is the terminating resistor (120 Ù) for the bus. Read more about the CAN bus in the service manual for the power source. 1AP1:3 Fault indication, panel M2 The M2 panel has a single fault--indicating LED, which is controlled by... -

1AP1:5 Display, panels MA4, MA6 and U6 The MA4, MA6 and U6 display panels are backlit by parallel--connected LEDs, controlled by transistor Q1. Display contrast can be adjusted by potentiometer R52: see the component positions diagram on page 7. 1AP1:6 Settings, panels MA4, MA6 and U6 The MA4, MA6 and U6 panels have pulse generators (encoders) for setting the welding voltage and wire feed speed, with pushbuttons for other functions. -

1AP1 Component positions The printed circuit board is the same, regardless of which type of panel it is used for. The picture above shows all the components with which the board may be fitted: the exact choice of components varies, depending on the panel. S0740 800 152/E061012/P36 - - 7 - - ci01d1... -
Page 8: Fault Codes
FAULT CODES Fault log All faults that occur when using the welding equipment are documented as error messages in the fault log: up to 99 error messages can be saved. When 99 messages have been saved, the oldest message will automatically erase when the next fault occurs. Only the most recent fault message is displayed on the control panel. -
Page 9: Fault Codes For The Ma4, Ma6 And U6 Panels
Fault codes for the MA4, MA6 and U6 panels Fault codes are updated every three seconds. They are shown on the display in the form of a symbol, as follows: The upper figure in the symbol is the number of the particular fault code. The lower figure indicates where the fault is: 0 = control panel 1 = cooling unit... -
Page 10: Fault Code Descriptions, Control Panel
Fault code descriptions, control panel The fault codes for the cooling unit, power source, wire feed unit and the remote control unit are described in the manuals for these units. This manual describes the fault codes for the control panel. Code Description EPROM check sum error -- program memory error This indicates a fault in the check sum test of the program memory, which is run only when... - Page 11 Something has prevented the processor from performing its normal program duties. The program restarts automatically. The current welding process will be stopped. This fault does not disable any functions. This fault should never occur in reality. Contact ESAB if the fault does occur. Stack overflow The program execution does not work.

Page 12: Service Instructions
SERVICE INSTRUCTIONS WARNING ! STATIC ELECTRICITY can damage circuit boards and electronic components. Observe precautions for handling electrostatic- - sensitive devices. Use proper static- -proof bags and boxes. What is ESD? A sudden transfer or discharge of static electricity from one object to another. ESD stands for Electrostatic Discharge. -
Page 13: Service Aid
The software update is made from a PC, it has to be managed by a trained serviceman. For this a computer program called Esat, ESAB software administration tool, is needed. The PC is connected to the welding equipment by a cable connector and a CAN reader. From the Esat it is possible to update the software in power source, wire feeder and control panel. -
Page 14: Exchange Circuit Boards
When an exchange circuit board is ordered, the defect board must be sent back to ESAB. Use only antistatic packaging materials for the circuit board. If we do not receive the defect board, or if it is not packed in antistatic packaging, the price for the exchange board will be 30 to 50% higher than the normal price. -
