GRAND ARC 320 CEL PFC MV – Lokermann

GRAND ARC 320 CEL PFC MV is an heavy duty industrial
multi voltage inverter power source for MMA (stick)
welding and Lift TIG DC applications with excellent


It is an MMA (stick) with an high no load voltage that give very good performance with cellulosic electrodes. Hot Start and Arc Force are adjustable in order give to the operator the best welding performance. Antisticking helps the welder stopping the welding current when the electrode is glued to the workpiece. VRD system (Voltage Reduction Device) is a device used for decrease the no load voltage during the stand by to allow to work in environments where security requires limited work voltages (shipyards, oil platforms, etc). P.F.C (Power Factor Corrector) reduce the harmonic current emissions and increase the power inverter efcency reducing the input current more than 20%. For the same reason it permits to have higher welding current than a standard inverter using a poor supply network and permit to use a very long supplying cables or a not stabilized line. Multi voltage device permit to connect the machine both in single phase both in three phases from 110v to 460v . It is equipped with temperature, voltage and current sensors for hight protection and it is designed to avoid failures due to voltage spikes as when using diesel generator. Extremely robust GRAND ARC 320 CEL PFC MV is developed for tough working condition such as pipe line, shipbuilding, offshore and heavy carpentry. A wireless remote control can be connected.
