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 more
precisely than previously possible. 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. T he new welding power sources are already prepared for straightforward
connection to the A2--A6 Process Controller (PEH). The welding power sources also
supply the correct current to the process controller, thus eliminating the need for any
external power supply.
