INTRODUCTION
This manual describes the control panels MA43 and MA44, who are used for setting and
displaying welding data in MIG/MAG- and MMA welding. MA44 includes all MA43 functions
and some additional features like QSetand synergic welding.
Each control panel consists of a front panel and a display board. It is connected, via a 34
part ribbon cable, to a microprocessor-equipped control board in a wire feeder unit.
The wire feeder control board contains the MMC control unit, and stores the welding data.
MA43
MA44
Pushbuttons are used for parameter selection and knobs for parameter settings (voltage,
wire feed speed, welding current, time etc.).
More control panel information is found in chapter Instructions, see page 15.

DESCRIPTION OF OPERATION
This description of operation describes the function of circuit board and other components
in the MMC module. It is divided into sections, numbered to correspond to the circuit board
numbers and divisions into function blocks.
Self-test
When mains power is switched on the welding data unit runs a self diagnostic program test.
1. The program memory of the welding data unit is checked by a check-sum test.
If the test detects a fault, fault code E1 will be logged.
2. LED test, display test and software version indication are enabled by visual inspection
The LED test starts with all LEDs dark, then they are turned on and off, one at a
time, until all LEDs have been tested. No fault code will be logged if this test
detects a fault.
The display segments are tested in the same way as the LEDs.
No fault code will be logged if this test detects a fault.
Finally the software version is displayed. In this example the
version is 0.17A.
Circuit board identity
The control board, 13AP1, is located in the wire feeder unit. It is functionally divided into two
parts: the wire feeder control unit and the MMC control unit (welding data unit) which
contains welding data.
Each part has a machine ID, a hardware ID, a unit type and a unit number. To read them
you need the ESAT service tool, see page 14.
The machine ID defines which type of wire feed/MMC unit the board is intended for. If
the board is to be used for another type of welding equipment, the machine ID can be
changed by ESAT.
The hardware ID shows design and type of circuit board.
The unit type and unit number are used for identification on the CAN bus.
Note! The ID numbers for the control board/welding data unit are found in the service
manual for the wire feeder.

Pushbutton monitoring
The front panel includes matrix connected pushbuttons. It also includes a
smart panel feature that makes the control board recognize the type of panel
attached.
The pushbuttons and the smart panel feature are multiplexed by the wire
feeder control board.

S0740 800 209/E101102/P22
1AP2:3
Encoder monitoring
The panels have pulse generators (encoders) for setting the welding voltage
and current, wire feed speed etc. Other settings are made with pushbuttons.
Turning the voltage adjustment pulse generator (SW2) briefly connects pin 2
(0V) to pins 1 and 3, but with a slight time difference between them. This
generates an A pulse and a B pulse that are displaced about 90° relative to
each other.
One square wave pulse train is used as clock frequency and the other square
wave pulse train defines the knob-turning direction by comparing the phase
position (positive or negative) to the clock pulse train.
When the pulse generator knob is not being turned, the voltage on pins 1 and
3 measures either 0V or 5V.
The wire feed speed pulse generator (SW1) operates in the same way.

FAULT CODES
Fault codes are used in order to indicate and identify a fault in the equipment.
Fault log
All faults that occur when using the welding equipment are documented as error messages
in the fault log. When the fault log is full, the oldest message will automatically be erased
when the next fault occurs.
Only the most recent fault message is displayed on the control panel. To read the entire
fault log, the machine must be connected to the ESAT: see service tools on page 14.
Faults are monitored/detected in two ways: by test routines that are run on initiation and by
functions that can detect a fault when it occurs.
Fault codes
The control panel displays a unit number to indicate which unit has generated the fault. The
following unit numbers are used:
U0 = welding data unit
(MMC)
U1 = cooling unit
U2 = power source
U3 = wire feed unit
U4 = remote control unit
U5 = pre reg unit
(multivoltage)
Fault codes are used to indicate that a fault has occurred in the
equipment. They are given in the lower part of the display with an
E followed by a fault code number.
A unit number is displayed to indicate which unit has generated the
fault.
Fault code numbers and unit numbers are shown alternately.
Example: Fault indication indicates that the control panel (U 0) has
lost contact with the power source (E 18).
If several faults have been detected only the code for the last
occurring fault is displayed. Press any function button or turn any
knob to remove the fault indication from the display.
Note! If the remote control is activated, you must press
(deactivating the remote control) to erase the fault indication.

SERVICE INSTRUCTIONS
CAUTION !
STATIC ELECTRICITY can damage circuit
boards and electronic components.
ESD
S
Observe precautions for handling electrostaticsensitive devices.
S
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.
How does ESD damage occur?
ESD can cause damage to sensitive electrical components, but is not dangerous to people.
ESD damage occurs when an ungrounded person or object with a static charge comes into
contact with a component or assembly that is grounded. A rapid discharge can occur,
causing damage. This damage can take the form of immediate failure, but it is more likely
that system performance will be affected and the component will fail prematurely.
How do we prevent ESD damage?
ESD damage can be prevented by awareness. If static electricity is prevented from building
up on you or on anything at your work station, then there cannot be any static discharges.
Nonconductive materials (e.g. fabrics), or insulators (e.g. plastics) generate and hold static
charge, so you should not bring unnecessary nonconductive items into the work area.
It is obviously difficult to avoid all such items, so various means are used to drain off any
static discharge from persons to prevent the risk of ESD damage. This is done by simple
devices: wrist straps, connected to ground, and conductive shoes.
Work surfaces, carts and containers must be conductive and grounded. Use only antistatic
packaging materials. Overall, handling of ESD-sensitive devices should be minimized to
prevent damage.

Symbol and function explanations
MIG/MAG welding
MIG/MAG welding melts a continuously supplied filler wire, with the weld pool being protected
by shielding gas.
MMA welding
MMA welding may also be referred to as welding with coated electrodes. Striking the arc melts
the electrode, and its coating forms protective slag.
Synergy
Each combination of wire type, wire diameter and gas mixture requires a unique
relationship between wire feed speed and voltage (arc length) to obtain a stable
functioning arc. The voltage (arc length) automatically conforms in accordance with
the pre-programmed synergic line you selected, which makes it much easier to find
the correct welding parameters. The connection between the wire feed speed and
the other parameters is called the synergic line. See the different synergic lines in
the Instruction manual.
QSett
QSet
, is used to facilitate setting welding parameters.
Turning the knob clockwise increases (+) the arc length.
Turning the knob anti-clockwise reduces (-) the arc length.
SHORT ARC
When first starting welding with a wire type / gas type QSetautomatically sets all
the necessary welding parameters. After that QSetstores all the data to produce
a good weld. The voltage then automatically conforms to changes in the wire feed
speed.
SPRAY ARC
When approaching the spray arc area the value for QSet must be increased.
Disengage the QSet function when welding with pure spray arc, All settings are
inherited from QSet, with the exception of the voltage which must be set.
Recommendation: Make the first weld (6 seconds) with QSet on a test piece to
obtain all the correct data.
ci26i1

S0740 800 209/E101102/P22
Manual
Manual operation. The operator must set appropriate values for the wire feed and
voltage.
Creep start
Creep starting feeds out the wire at 50% of the set speed until it makes electrical
contact with the workpiece.
Crater filling
Crater filling time
Crater filling helps to avoid pores, thermal cracking and crater formation in the weld
when welding stops.
2-stroke
With 2-stroke gas pre-flow (if used) starts when the welding gun trigger switch is
pressed. The welding process then starts. Releasing the trigger switch stops weld­
ing entirely and starts gas post-flow (if selected).
4-stroke
With 4 stroke, the gas pre-flow starts when the welding gun trigger switch is
pressed in and the wire feed starts when it is released. The welding process
continues until the switch is pressed in again, the wire feed then stops and when
the switch is released the gas post-flow starts (if selected).
Active panel
Settings are made from the control panel.
Changing welding data
This function permits changing between different welding data memories by a press
on the trigger of the welding gun.
To change without ongoing welding press quickly. If the trigger is held depressed for
too long, the program interprets this as a welding start.
Changing welding data during welding with 2-stroke
During ongoing welding the welding gun's trigger is depressed. To change welding
data memory, release the trigger and depress it quickly.
Changing welding data during welding with 4-stroke
During ongoing welding with 4-stroke the welding gun's trigger is released. To
change welding data memory, depress the trigger and release it quickly.
ci26i1

S0740 800 209/E101102/P22
Remote control unit
Settings are made from the remote control unit.
The remote control unit must be connected to the remote control unit socket on the
machine before activation. When the remote control unit is activated the panel is
inactive.
With the remote control unit function activated one can change between different
welding data memories using a welding gun with program selector (RS3).
VRD (Voltage Reducing Device)
The VRD function ensures that the open-circuit voltage does not exceed 35 V when
welding is not being carried out. This is indicated by a lit VRD LED.
The VRD function is blocked when the system senses that welding has started.
If the VRD function is activated and the open-circuit voltage exceeds the 35 V limit,
this is indicated by an error message (16) appearing in the display and welding
cannot be started whilst the error message is displayed.
Gas purging
Gas purging is used when measuring the gas flow or to flush any air or moisture
from the gas hoses before welding starts. Gas purging occurs for as long as the
button is held depressed and occurs without voltage or wire feed starting.
Wire inching
Wire inching is used when one needs to feed wire without welding voltage being
applied. The wire is fed as long as the button is depressed.
Inductance
Higher inductance results in a wider weld pool and less spatter. Lower inductance
produces a harsher sound but a stable, concentrated arc.
Hidden MIG/MAG functions
There are hidden functions in the control panel.
To access these hidden functions hold the button
depressed for 5 seconds. The
display will show a letter and a value. The knob for wire feed is used to change the
value of the selected function.
