1 INTRODUCTION
The manual describes use of the A44 control panel.
NOTE! Differences in the panel function may occur, depending on in which product it
is installed.
For general information about operation see user's instructions for the power source.
When mains power is supplied the unit runs a self diagnosis of the
LEDs and the display, the soft ware version is displayed and in this
example the soft ware version is 0.18.
Instruction manuals in other languages can be downloaded from the website,
www.esab.com.
1.1 Control panel A44
Display
Indication of which parameter is shown in the display (current, voltage or
percent)
Display of measurement value for current (A) or voltage (V) during welding.
Knob for setting data (current, voltage or percent)
Buttons for weld data memory settings. See section 5.

Button for choosing parameters ”Hot start” or arc pressure ”Arc force”
when MMA welding or inductance when MIG/MAG welding
Selection of welding method
MMA
, MIG/MAG, FCAW-S or TIG
Choice of electrode type ”Basic”, ”Rutile” or ”Cellulose” when MMA welding
Setting from panel and connecting remote control unit
Display of VRD function (reduced open-circuit voltage)
Measured value in the display for arc voltage V, and welding current A, is arithmetic
average value = rectified average value.

2.2 Symbol and Function explanations
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.
Setting current
A higher current produces a wider weld pool, with better penetration into the
workpiece.

Active panel
Settings are made from the control panel.
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.
Hot Start
”Hot start” increases the welding current during a fixed period at the start of the
welding process. Set the start current at a % of the set welding current using the
knob. This reduces the risk of incomplete fusion at the start of the weld.
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.
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.
Contact an authorised ESAB service technician to activate the function.
