1 INTRODUCTION
The manual describes use of A32, A33 and A34 control panels.
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 program version is displayed and in this
example the program version is 0.18.

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
Increases the welding current during a fixed time at the start of the welding process.
Set the value of the hot start current by 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 Reduction Device)

NOTE! The VRD function is not active (LED has gone out) on delivery. Contact an
authorised ESAB service technician to activate the function.
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 deactivated when the system senses that welding has started.
If the VRD function is activated and 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.

2.3 Hidden functions MMA welding

There are hidden functions in the control panel.

To access the functions in A32, use the method button, .

To access the functions in A33 and A34, hold button depressed for 5 seconds.
The display shows a letter and a value. The correct function is selected by pressing
the buttons. The knob is used to change the value of the selected function.

Function letter Function

C Arc Force
H Hotstart
d Drop welding

To leave the function in A32, hold the button depressed for 5 seconds. For A33

and A34, hold the button depressed for 5 seconds.

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.

Hot Start
Increases the welding current during a fixed time at the start of the welding process.
Set the value of the hot start current by using the knob. This reduces the risk of
binding defects at the start of the weld.

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.

3.2 Symbol and Function explanations

TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten elec-
trode, which does not melt itself. The weld pool and the electrode are protected by
shielding gas.

”LiveTig start”
With “LiveTig start” the arc strikes when the tungsten electrode is brought into
contact with the workpiece and then lifted away from it.

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.

VRD (Voltage Reduction Device)

NOTE! The VRD function is not active (LED has gone out) on delivery. Contact an
authorised ESAB service technician to activate the function.
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 deactivated when the system senses that welding has started.
If the VRD function is activated and 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.

4 WELDING DATA MEMORY

Two different welding data programs can be stored in the control panel memory.

Press button or for 5 seconds to store the welding data in the

memory. The welding data is stored when the green indicator lamp starts to flash.

To switch between the different welding data memories press button or

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

5 FAULT CODES
Fault codes are used to indicate that a fault has occurred in the equipment. It is
indicated in the display by an E followed by a fault code number.
A unit number is displayed to indicate which unit has generated the fault, for example
U 0.
If several faults have been detected only the code for the last occurring fault is
displayed. Press any function button or turn the knob to remove the fault indication
from the display.
NOTE! If the remote control unit is activated, deactivate the remote control unit by
pressing to remove the fault indication.

5.1 List of fault codes

Unit number:
U 0 = welding data unit U 2 = power source
U 4 = remote control unit

5.2 Fault code descriptions

The fault codes that the user can correct themselves are given below. If a different
code appears, call a service technician.

Fault Description
code
E6 High temperature
The thermal overload cut--out has tripped.
The current welding process is stopped and cannot be restarted until the temperature has
fallen.
Action: Check that the cooling air inlets or outlets are not blocked or clogged with dirt.
Check the duty cycle being used, to make sure that the equipment is not being overloaded.
E 14 Communication error (bus off)
Serious interference on the CAN bus.
Action: Check that there are no faulty units connected on the CAN bus. Check the cables.
Send for a service technician if the fault persists.
E 16 High open--circuit voltage
Open circuit voltage has been too high.
Action: Turn off the mains power supply to reset the unit. Send for a service technician if
the fault persists.
E 19 Memory error
Content of existing memory is incorrect. Basic data will be used.
Action: Turn off the mains power supply to reset the unit. Send for a service technician if
the fault persists.
