1 INTRODUCTION

1.1 Overview

The manual describes the use of the A32,A33 and A34 control panels.

For general information about the operation see the Instruction manual for the power source.

When the mains power is supplied, the unit runs a self diagnosis of the LEDs and the display, the program version is displayed, in this example the program version is 0.18.

NOTE!

There may be differences in the way the panel functions, depending on the product in which it is installed.

Instruction manuals in other languages can be downloaded from the Internet: www.esab.com

2.2 Explanation of symbols and functions

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.

Current setting

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 equipment 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.

2 MMA WELDING

Voltage Reducing Device (VRD)

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 detects 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 authorized ESAB service technician to activate the function.

2.3 Hidden functions MMA welding

There are hidden functions in the control panel.

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

To access these functions in A33 and A34, hold the 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.

d Drop welding

To exit the function in the 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

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 heat supply. The electrode needs only to be raised slightly to extinguish the arc.

3.2 Explanation of symbols and functions

TIG welding

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

Live TIG-start

At a "Live TIG-start", the tungsten electrode is placed against the workpiece. When the electrode is lifted away from workpiece, the arc is struck at a limited current level.

3 TIG WELDING

HotWireTIG

This function uses the power source to pre-heat a wire fed to an existing TIGmelt. This results in a higher rate of production and also a better welding result than is the case if a cold wire is fed to the melt.

When the HotWireTIG function as been turned on using the "h" parameter, the functionality is as follows. If a triggersignal is generated, or the "S" parameter (see below) is set to "1", pre-heating will start and Hot Wire TIG will be indicated by the TIG indicator flashing.

If the voltage reaches a certain limit, an arc is considered to have formed and the power source tries to extinguish it. This is because the purpose of HotWireTIG is not to keep an arc lit, but to maintain a constant current to heat the wire. You can set the voltage limit, using the "U" parameter (see above).

In a system without a triggersignal, the "S" parameter can be used to start pre-heating automatically.

WARNING!

When the "S" parameter is in position "1", there is a constant voltage on the welding output. This is indicated by the VRDindicator flashing.

4 WELDING DATA MEMORY

Two different sets of welding data 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 battery, so the settings are retained even if the unit is switched off.

5 FAULT CODES

5.1 General

Fault codes are used to indicate that a fault has occurred in the equipment. They are 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 fault occurring is displayed. Press any function button or turn the 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.

5.2 List of fault codes

Unit number:

U 0 = welding data unit U 2 = power source

U 4 = remote cooling unit

5.3 Fault code descriptions

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

Fault code Description

E 6 High temperature

The thermal overload cutout has tripped.

The current welding process has stopped, and cannot be restarted until the cutout has reset.

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 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

The open-circuit voltage has been too high.

Action:Turn of the mains power supply to reset the unit. Send for a service technician, if the fault persists.

E 19 Memory error

Content of current memory is incorrect. Basic data will be used.

Action:Turn of the mains power supply to reset the unit. Send for a service technician, if the fault persists.
