VERTICAL STROKE SPOT WELDERS

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.
