INTRODUCTION
The manual describes use of MA23 and MA24 control panels.
For general information about operation see user's instructions for the power source
respectively wire feed unit.
When mains power is supplied the unit runs a self diagnosis of the
LEDs and the display, the program version is displayed and in this
example the program version is 0.17A
Instruction manuals in other languages can be downloaded from the website,

Symbol and function explanation
MIG/MAG welding
MIG/MAG welding melts a continuously supplied filler wire, with the weld pool being
protected by shielding gas.
Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
-5bi21d1ea

GB
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 on
page 14.
It is also possible to order other synergy lines, but these must be installed by an
authorised ESAB service engineer.
When activating synergy
also select synergy option
using the setting
knob.
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.
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.
-6bi21d1ea

GB
Crater filling
Crater filling time
Crater filling helps to avoid pores, thermal cracking and crater formation in the weld
when welding stops.
When activating crater filling
also select crater filling time
using the
setting knob.
This function cannot be used with QSet.
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.
When activating welding data
select welding data memory
or

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.
2.3
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.

Gas pre-flow
This controls the time during which shielding gas flows before the arc is struck.
Unit of measurement
0 = inch/min, 1 = mm/min, Default value = 1
Burnback time
Burnback time is a delay between the time when the wire starts to brake until the
time when the power source switches off the welding voltage. Too short burnback
time results in a long wire stickout after completion of welding, with a risk of the
wire being caught in the solidifying weld pool. Too long a burnback time results in a
shorter stickout, with increased risk of the arc striking back to the contact tip.
Gas post-flow
This controls the time during which shielding gas flows after the arc is extinguished.
Creep start
Creep starting feeds out the wire at 50% of the set speed until it makes electrical
contact with the workpiece.

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.

Arc force
The arc force is important in determining how the current changes in response to a
change in the arc length. A lower value gives a calmer arc with less spatter.
Drop welding
Drop welding can be used when welding with stainless electrodes. The function
involves alternately striking and extinguishing the arc in order to achieve better
control of the supply of heat. The electrode needs only to be raised slightly to
extinguish the arc.
Hot start
Hot start increases the weld current for an adjustable time at the start of welding,
thus reducing the risk of poor fusion at the beginning of the joint.
Welding regulator
Welding regulator is a type of control that produces a more intense, more
concentrated and calmer arc. It recovers more quickly after a spot short-circuit,
which reduces the risk of the electrode becoming stuck.
ArcPlus (0) is recommended with basic type of electrode
ArcPlusll (1) is recommended with rutile and cellulosic type of electrode
Min current
Used to set the minimum current for the remote control T1 Foot CAN.
If the max current is 100 A and the min current is to be 50 A, set the concealed
function min current to 50%.
If the max current is 100 A and the min current is to be 90 A, set the min current to
90%.

or
pressed in for 5 seconds to store welding
data in the memory. The welding data is stored when the green indicator lamp starts
to flash.

The welding data memory has a back-up battery so that the settings remain even if
the machine has been switched off.

FAULT CODES
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.
Fault indication indicates that the control panel (U 0) has lost
contact with the power source.
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, deactivate the remote control by pressing
to remove the fault indication.
