PPS - Vertical Stroke Spot/Projection Welder - AC - Single Phase

RWMA Member
  • Overview

     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
