Three-phase alternator PW2

2-pole

The PW2 and PW3 generators–welders series are brush-type 2 pole alternators with compound or compound-electronic regulation. This feature guarantees output voltage precision and motor-starting capability. Created due to well-established and continuous experiences in the welding sector, this rotating DC welder series has models with 3 phase and derived 1 phase or pure 1 phase generator output. A unique characteristic of the series (models 200, 220) is that it automatically disconnects the generator output when it is being used in the welder function. This avoids having dangerous voltage and prevents overload. Instead, in the generator function, there is a protection which, due to its specifi c system characteristics, prevents dangerous voltages in the generators – in case of accidental short circuit in the welding part. The selection of the required function, and of the output current regulation current, is governed by two commutators in the rear panel. Again… a variety of socket boxes allows confi guration of the socket on the side of the unit for maximum access. The frame is made of Fe P12 steel, and all shafts are C45, to ensure the unit can withstand rugged environments and is resistant to vibration. All units have insulation system to Class H requirements through advanced impregnation processes and material selection. The PW series has been engineered to satisfy the end-user that has specifi c medium power requirements and it allows the use of single or three phase utensils and of a DC welder which uses all types of electrodes (rutile, basics, cellulosics).
