ROCKER ARM, FOOT OPERATED, SPOT WELDERS - ITEMS 4602N-4606N - 16 TO 25 kVA AT 50%
MAIN WELDER FEATURES  
Items 4602N-4606N
  • Adjustable arms up to 320 mm, enabling to adjust the welder according to the work exigencies.
  • Chrome-copper electrode-holders for heavy duty and long life, designed for both straight and angled assembling.
  • Adjustable electrodes stroke, enabling to reach the max. working rate.
  • Water-cooled transformer, with epoxy resin coated windings.
  • Water cooled arms, electrode-holders and electrodes.
  • Synchronous SCR contactor insulated from cooling water circuit with protection thermostat.
  • Adjustable electrodes force, a microswitch starts the welding cycle when the desired pre-set value is reached by operating the foot control.
  • Foot control adjustable in length.
