Suitable for both spot and projection welding, PPN models
fully satisfy a wide range of the heaviest large production industrial
applications.
Equipped with microprocessor control, safety concomitant side buttons,
electric pedal and solenoid valve, upon request they can be fitted with
special controls to suit any special configurations.
Synchronous ignition SCR
group with phase shift welding current adjustment to eliminate switching
transistors.
Set up time reduction thanks a quick and easy
modification of electrodeholders platens opening
without any intervention on the secondary circuit (patent pending).
Self-lubricated pneumatic components to
eliminate oil deposits and to safeguard the environment
from contaminants.
Upper electrode movement by
self-lubricated double effect pneumatic cylinder fitted with speed
regulator, end stroke shock-absorber and silencer for compressed air
discharge.
Safety cycle start by means of the
concomitant side buttons or, as alternative only if the operator
can work in safe conditions, by electric pedal. Either
option can be chosen by a selector key.
