3 INTRODUCTION

3.1 General

ESAB’s A2--A6 Process Controller (PEH) is a control unit which, when combined withA2--A6 automatic welding equipment can be used for submerged--arc or MIG/MAGwelding.

The process controller is designed for use with ESAB’s LAF and TAF welding powersources. Close integration of the control system with the welding power sourcemakes it possible to ensure very precise process reliability.

All the controls that are needed to control welding travel and the entire weldingprocess are situated on the control panel.

Incoming cables from various system components are connected to sockets at therear of the process controller or to the circuit board terminals inside the controller.

3.2 Welding power sources

The welding power sources are specially adapted to work with the A2--A6 ProcessController. The welding power source and process controller are connected by a twinwire bus that allows the welding process to be controlled and monitored much moreprecisely than previously possible. The power source settings can be adjusted fromthe control panel on the process controller.

ESAB’s earlier generation of welding power sources, such as the LAH, LAE and TAEcan be adapted for use with the new process controller with the aid of a conversionkit. The new welding power sources are already prepared for straightforwardconnection to the A2--A6 Process Controller (PEH). The welding power sources alsosupply the correct current to the process controller, thus eliminating the need for anyexternal power supply.

5 OPERATIONAL DESCRIPTION

5.1 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 andyou can preset all other essential welding parameters for the current weld.

In automatic mode you can choose a preset group of welding parameters andfine--tune the actual welding parameters. Other settings made previously in manualmode cannot be adjusted in automatic mode.

The process controller is ready for manual operation as soon as the mains power isswitched on. When welding begins the controller switches to automatic mode. Whenwelding stops, or if there is a fault, the controller switches back to manual mode.

9.3 Definitions

1. DirectionTwo alternatives can be chosenY (triangle) and J (square) (these symbols arerepeated on all units)

S Y (triangle) indicates travel in one direction.

S J (square) indicate

2. StartTwo alternatives can be chosen: Direct start or Scratch start.

S Direct start means that travel starts when the arc ignites.

S Scratch start means that travel starts at the same time as wire feed. Scrapestart is used when welding rusty or dirty material.

3. STOP WELDINGCrater fill and Burnback time can be set.

Crater fill times between 10 and 3000 ms (0.01 -- 3 sec.) can be selected.The crater fill function is used to finish the weld without leaving a crater. Crater fill

starts when the welding stop key is pressed, and continues for the preset craterfill time. This function is most useful when MIG/MAG welding.

Burnback times between 10 and 3000 ms (0.01 -- 3 sec.) can be selected.

The burnback time starts after the crater fill sequence has ended.

Correct choice of the burnback time prevents:

S the wire sticking to the work piece

S the wire sticking to the nozzle

Wire diameter

The chosen wire diameter has a big effect on the start cycle and crater filling. Whenwelding with a wire diameter that is not given in the options table, choose the nearestdiameter from the menu.

Note! For certain wire materials a better welding result can be achieved, if a valuedeviating from the real wire dimension by 1 step is set (normally 1 step from the realvalue).

When metric units are used the following alternatives are available:

S solid wire 0.8 / 1.0 / 1.2 / 1.6 / 2.0 / 2,4 / 3.0 / 3.2 / 4.0 / 5.0 / 6.0 mm

S cored wire 0.8 / 1.0 / 1.2 / 1.6 / 2.0 / 2,4 / 3.0 / 3.2 / 4.0 mm

S strip 30 x 0.5 / 60 x 0.5 / 100 x 0.5 mm

When inch units are used the following alternatives are available

S solid wire 0.030, 0.040, 0.047, 1/16, 5/64, 3/32, 7/64, 1/8, 3/32,7/64, 1/8, 5/32, 3/16, 1/4

S cored wire 0.030, 0.040, 0.047, 1/16, 5/64, 3/32, 7/64, 1/8, 3/32,7/64, 1/8, 5/32

S strip 30 x 0,5 / 60 x 0,5 / 100 x 0,5

Wire composition

When welding with different filler materials the start and stop method is affected bythe choice of materials. It is therefore important that the settings show whether youare welding with steel--based or aluminium--based filler wires.

S Fe Steel filler wire

S Al Aluminium filler wire

S SS Stainless steel filler wire

Number of wires

Values between 1 -- 2 can be entered.For example, if welding with two wires (Twin Arc) enter the value 2.

5. RegulationTwo different operating modes can be used for welding, either constant current, CA,or constant wire feed speed, CW.

S CA, constant current. Normally used for submerged arc welding, which involvesworking with large welds, large currents and large weld pools. The wire feedspeed is controlled by the power source to maintain a constant current.

S CW, constant wire feed speed. Normally used for MIG/MAG welding, for smallweld pools, thin sheet metal and thin filler wire. It is easier to achieve a constantthroat thickness when welding with this method. Welding is controlled byselecting a fixed wire feed speed and the current is adjusted to achieve thisspeed. The resulting current is displayed above the selected wire feed speed(see display shot on page 96).
