SAFETY Users of ESAB welding equipment have ultimate responsibility for ensuring that any- one who works on or near the equipment observes all the relevant safety precau- tions. Safety precautions must meet the requirements that apply to this type of welding equipment.
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 integration of the control system with the welding power source makes it possible to ensure very precise process reliability.
The 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.
OPERATIONAL DESCRIPTION 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.
MANUAL OPERATION Travel and wire feed Travel and wire feed commands can be given when not welding, as follows: Switch on welding power source The direction of travel is as shown by the square symbol on the power source. Normal speed The direction of travel is as shown by the triangular symbol on the power source.
MENUS Menu overview The A2--A6 Process Controller (PEH) software is divided into several menus. The program structure is described in the overview below. MAIN MENU MAIN MENU S SET S Heat input per cm S Welding current S Wire feed speed S Arc voltage S Travel speed S Preset indicators WELDING SETUP S Arc start method S Type of weld finish...
MAIN MENU In the main menu you choose the welding current, arc voltage and travel speed you want to use for welding. During welding you can adjust the welding parameters or choose a complete new set of parameters. Switch on the power source The main menu will appear as follows: Example of display if constant current (CA) has been chosen.
Entering welding parameters When the power source is switched on, the main menu appears on the display. In the “Display menu” you can choose how many sets of parameters you want to work with. If more than one set of parameters is used then the SET number appears in the top left corner.
Adjusting parameter values (during welding) Once welding has started the welding parameters can be fine--tuned using the arrowed numerical keys. Increase Decrease Welding current or wire feed speed Arc voltage Travel speed Save the values as follows: Stop welding with .
Press The field “SET 6” is marked and parameter set 6 is active Check before choosing Suppose that while welding with parameter set 1 (“SET 1”) you decide to change to parameter set 6 (“SET 6”) after first checking the parameters. Mark the field “SET 1 “...
Return to the previous row by pressing This combination will also take you straight to row 6 from row 1 Explanations of terms: When is indicated in combination with another key you should press first and hold it down while pressing the second key. Available settings WELDING SETUP (TRIANGLE),...
Definitions Direction Two alternatives can be chosen Y (triangle) and J (square) (these symbols are repeated on all units) Y (triangle) indicates travel in one direction. J (square) indicate Start Two alternatives can be chosen: Direct start or Scratch start. Direct start means that travel starts when the arc ignites.

WIRE DATA Wire type The equipment can be preset for the wire you intend to weld with. The control system must be given information about the wire shape in order to achieve optimum start/stop characteristics. solid wire cored wire strip Wire diameter The chosen wire diameter has a big effect on the start cycle and crater filling.
Control Two different operating modes can be used for welding, either constant current, CA, or constant wire feed speed, CW. CA, constant current. Normally used for submerged arc welding, which involves working with large welds, large currents and large weld pools. The wire feed speed is controlled by the power source to maintain a constant current.
* Inputs are activated by using settings in menu “PRESET SYSTEM MENU”. ORDERING SPARE PARTS Spare parts are ordered through your nearest ESAB representative, see back cover. When ordering spare parts, please state machine type and number as well as desig- nation and spare part number as shown in the spare parts list on page 36.
