The LAF series are three phase, fan-cooled DC welding power sources designed for high productivity mechanized Submerged or high productivity MIG/MAG arc welding.
They are used in combination with ESAB’s A2-A6 equipment range and the A2-A6 Process Controllers (PEK or PEI).
LAF welding power sources have 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.
The welding power source can be adjusted and monitored from the front panel of the process controller (PEK or PEI), which permits easy adjustment of all welding parameters. The welding current range can be extended by connecting two power sources in parallel for the most demanding application.
