Product Description
Vertical Stroke Spot And Projection Welders:
Being suitable for both spot and projection welding jobs, PPN models fully satisfy an extremely large variety of the heaviest mass production industrial applications. Equipped with a microprocessor control and safety concomitant side buttons, upon request they can also be supplied fitted with special controls and in different configurations
- Excellent Welding on all weldable metals
- Synchronous ignition SCR group with phase shift welding current adjustment to eliminate initial transient
- Thermostatic protection on the SCR group
- High welding currents with low consumption
- Set up time reduction thanks to quick and easy modifications to electrodeholders platens opening without any intervention on the secondary circuit (patent pending)
- Self-lubricated pneumatic compliments to eliminate oil deposits and to safeguard the environment from contaminants
- Water cooled secondary circuit, i.e. electrodes, electrodeholders, platens and transformer, to avoid overheating
- Water cooled copper electrodeholders with adjustable height
- Electrode force adjustable by pressure reducer group equipped with a monometer and filter for automatic air impurity expulsion
- Upper electrode movement by self-lubricated double effect pneumatic cylinder fitted with speed regulator, end stroke shock-absorber and silencer for compressed air discharge
- Solenoid valve to control welding cylinder
- Safety cycle start by means of concomitant side buttons or, alternatively only if the operator can work in safe conditions, by electric pedal. Either option can be chosen by a selector with removable key
- Cycle stop emergency button
PPN 63
THEY ARE EQUIPPED WITH:
- Lower round arm with adjustable height and lateral adjustment
- Electrodeholders with electrodes for spotwelding and ability to easily fit barholders for projection welding
- Lower arm holder can be adjusted for use with larger arm gap
- Spotwelding
- Projection welding with bars for mesh
UPON REQUEST ALSO AVAILABLE WITH:
- Different length arms (optional)
