1SAFETY
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 recommen-
dations should be observed in addition to the standard regulations that apply to the workplace.
All work must be carried out by trained personnel well--acquainted 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 location of emergency stops
S its function
S relevant safety precautions
S welding
2. The operator must ensure that:
S no unauthorised person is stationed within the working area of the equipment when it is
started up.
S no--one is unprotected when the arc is struck
3. The workplace 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 may 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
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-
TIONS 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 take fumes and gases away 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 s uitable 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 earmuffs or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!

2 INTRODUCTION
2.1 General
ESAB’s A2--A6 Process Controller (PEH) is a control unit which, when combined with
A2--A6 automatic welding equipment can be used for submerged--arc or MIG/MAG
welding.
The process controller is designed for use with ESAB’s LAF and TAF welding power
sources. Close integr ation of the contr ol system with the welding power source
makes it possible to ensure very precise process reliability.
All the controls that are needed to control welding travel and the entire welding
process are situated on the control panel.
Incoming cables from var ious system components are connected to sockets at the
rear of the process controller or to the circuit board terminals inside the controller.
2.2 Welding power sources
The welding power sources are specially adapted to work with the A2--A6 Process
Controller. The welding power source and process controller are connected by a twin
wire bus that allows the welding process to be controlled and monitored much m ore
precisely than previously possible. T h e power source settings can be adjusted from
the control panel on the process controller.
ESAB’s earlier generation of welding power sources, such as the LAH, LAE and TAE
can be adapted for use with the new process controller with the aid of a conversion
kit. T he new welding power sources are already prepared for straightforward
connection to the A2--A6 Process Controller ( PEH). T he welding power sources also
supply the correct current to the process controller, thus eliminating the need for any
external power supply.

4 OPERATIONAL DESCRIPTION
4.1 General
Switch on welding power source
The process controller can be used in manual or automatic mode.
In manual mode the wire feed speed and travel speed are controlled manually and
you can preset all other essential welding parameters for the current weld.
In automatic mode you can choose a preset group of welding parameters and
fine--tune the actual welding parameters. Other settings made previously in manual
mode cannot be adjusted in automatic mode.
The process controller is ready for manual operation as soon as the mains power is
switched on. When welding begins the controller switches to automatic mode. When
welding stops, or if there is a fault, the controller switches back to manual mode.
4.2 Control panel
1. Emergency stop
2. The direction of travel is as shown
by the triangular symbol on the
welding equipment.
3. The direction of travel is as shown
by the square symbol on the welding
equipment.
