This series of welder – generators has been designed to ensure high performance, and maintenance free operation. The EPW3; EPW4; EPW5 welder- generators are brushless excitation (with rotating diode) and a total electronic regulation, in fact the generator is regulated to EVR01 regulator, and the welding current is regulated to “chopper” system for obtain good quality of welding (D.C. high frequence 40KHz) Over and beyond a high use factor at average voltages and at an almost free maintenance, this system also allows for simultaneous of the alternator and the welder; in fact due to the special circuitation, the whenever the welder is being used at the same time. The special circuitation also permits the forcing of the arc, anti – blockage, and is protected agaisnt short circuits on exit from welding.
The EPW3-4-5 series has been sized to satisfy the most professional requirements of the welding sector , as it can be employed with high duty cicles in sinergy with a three phase alternator which has optimum characteristics. Obviously all types of electrodes can be welded (rutile , basic cellulosic).
