2SAFETY
Users of ESAB welding equipment have the ultimate responsibility for ensuring that anyone who
works on or near the equipment observes all the relevant safety precautions.
Safety precautions must meet the requirements that apply to this type of welding equipment.
The following recommendations should be observed in addition to the standard regulations that apply
to the work place.
All work must be carried out by trained personnel well familiar with the operation of the welding equipment.
Incorrect operation of the equipment may lead to hazardous situations which can result in injury to the
operator and damage to the equipment.
1. Anyone who uses the welding equipment must be familiar with:
S its operation
S its function
S relevant safety precautions
S welding
2. The operator must ensure that:
S no unauthorized person is stationed within the working area of the equipment when it is
started up.
S that no--one is unprotected when the arc is struck
3. The work place must:
S be suitable for the purpose
S be free from draughts
4. Personal safety equipment
S Always wear recommended personal safety equipment, such as safety glasses, flame--proof
clothing, safety gloves.
S Do not wear loose--fitting items, such as scarves, bracelets, rings, etc., which could become
trapped or cause burns.
5. General precautions
S Make sure the return cable is connected securely.
S Work on high voltage equipment shall only be carried out by a qualified electrician.
S Appropriate fire extinquishing equipment must be clearly marked and close at hand.
S Lubrication and maintenance must not be carried out on the equipment during operation.

WARNING
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAUTIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK -- Can kill
S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to keep fumes and gases from your breathing zone and
the general area.
ARC RAYS -- Can injure eyes and burn skin.
S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
S Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
S Protect your ears. Use ear defenders or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
PROTECT YOURSELF AND OTHERS!
3 INTRODUCTION
3.1 General
The welding motion is controlled over the PAL 3 motor control unit and an external
motor regulator. The control unit can be fitted to the LTP 450 (Protig) and the LTS
320 (Prowelder) power sources for the control of wire feed, roller beds, turntables
and positioners, for example.
The control unit is used in plants where the rotary motion is effected by way of
motors stronger than the ESAB VEC 1000 rpm.
The unit gives a speed reference of 0--10 V. It is provided with two relays emitting
signals for forward and backward control and some extra inputs for external start and
stop, for example.
A two--channel pulse transmitter fitted to the motor shaft is required as feed--back
enabling the power sources to keep the positioning under control. This applies to
welding programs with more than one sector.
Instead of the pulse transmitter an external input can be used for changing sectors.
3.2 Voltage supply
The motor control unit is supplied with 42 V AC over the pins XP1.J and XP1.B of the
CAN terminal.

GB
3.3 Speed reference
An analogue signal between +0.5 V and +10 V is emitted for the welding motion.
The voltage is proportional to the programmed speed value, i.e. the value 1000 rpm
will result in +10 V and 500 in +5 V.
To protect the machine from disturbances and earth fault the signal is galavanically
separated from other electronics by way of reinforced insulation.

Speed reference +0.5 V -- +10 V
Max. load 5mA

3.4 Pulse transmitter inputs
The pulse signal lies between 0 and 24 V over the two ranges.
In order to protect the machine from earth fault and disturbances the inputs are
insulated by way of opto--couplers.

Range of frequencies 25--1700 Hz / 200--13600 Hz
Current 15 mA

3.5 Relay outputs
The board has two separate relay outputs with alternating functions. The outputs are
used for controlling the forwa rd and backward motions.
Forward: RE1--Off RE2--On
Backward: RE1--On RE2--Off
Idle: RE1--Off RE2--Off

3.6 Additional inputs/outputs
The board contains five extra ports to be used as digital inputs/outputs. When they
are used as inputs the +15 V voltage of the board itself must be fed back to get a
high signal. A 10 ms long signal is required to enable the control unit to register the
change.
If the ports are used as outputs only the processor will be driving. Therefore, a
galvanically insulated drive must be connected if other electronics are to be used.
