Esab Welding & Cutting Products has introduced new LAF DC power sources.

The LAF series are three-phase, fan-cooled DC welding power sources designed for high productivity mechanised submerged arc welding or high productivity GMAW welding. They are designed to be used in combination with ESAB’s A2-A6 equipment range and the A2-A6 Process Controllers (PEK or PEI).

“LAF welding power sources offer excellent welding characteristics throughout the entire current and voltage range, with particularly good starting and re-ignition properties. These power sources demonstrate good arc stability at both high and low arc voltages,” Esab said.

“The welding power source can be adjusted and monitored from the front panel of the process controller for easy adjustment of all welding parameters. The welding current range can be extended by connecting two power sources in parallel for the most demanding applications.”

Communication vital
The power sources are designed to be used with the fully digital PEK controller for maximum functionality or with the PEI controller with basic functionality for less demanding applications. Communication is vital in automation applications.

Therefore the power source is prepared for communication using most standard protocols including TCP/IP (LAN), Anybus, Profibus, CAN or even straight communication with a PLC.
