Particularly studied for spot welding.
Common Characteristics
Particularly studied for spot welding, PPS model fully satisfy a wide range of the heaviest large production industrial applications. Equipped with microprocessor control, solenoid valve, upon request they can be fitted with safety concomitant side buttons and any special configurations.
FEATURES
• Excellent welding on all weldable metals
• Synchronous ignition SCR group with phase shift welding current adjustment to eliminate switching transistors
• Thermostatic protection on the SCR group
• High welding currents with low consumption
• Self-lubricated pneumatic components to eliminate oil deposits and to safeguard the environment from contaminants
• Water cooled secondary circuit, i.e. electrodes, electrodeholders, platens and transformer, to avoid any overheating
• Water cooled copper electrodeholders with adjustable height
• Electrode force adjustable by pressure reducer group equipped with a manometer 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
• Manual valve for upper head descent without pressure for cleaning, centering and ordinary maintenance of the electrodes
• Solenoid valve to control welding cylinder
• Cycle stop emergency button.
PPS 35 and PPS 60:
Lower round arm with adjustable height and lateral adjustment.
Inferior arm holder can be rotated for use with larger arm gap.
