This power source is a power supply where the intensity is imposed at all times. The
system stability relies on an electronic current regulation system that can react at the speed
of the arc.
It is cooled by a forced ventilation system. Filters placed on the air inlets extend the life
of the components of the power source when it is used in dusty environments.
The cooling air is taken in through openings in the side panels and the upper front door
and then transferred to the rear by means of a fan.
NERTAMATIC 450 has several auxiliary power supply systems, which are alternative low-
voltage sources that power the cycle box, the AVC, the wire feeding funcion, the BRT, some
movements etc.
It offers an internal visualisation of its operating status and a galvanised insulated interface
for dialogue with the “outside”.
