- Linear action spot welders - 35-50 kVA

 

Items 4625N-4630N - Linear action spot welders - 35-50 kVA MAIN WELDER FEATURES
  • Linear action pneumatic spot welder with TE90 microprocessor welding control unit.
  • Optional TE 180 and TE 185 control units.
  • 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.
  • All models have been designed for both single and automatic cycle.
  • Two stage electric foot control for clamping and welding pieces only if correctly positioned.
  • The welder has been designed for connecting a second two stage electric foot. This additional electric foot enables the recalling of the twin pre-setting for time and current, useful when it is necessary to carry out two different welds on the same piece.
  • Cylinder with chrome plated stem for heavy duty works and long life. Adjustable anti-rotation device.
  • Cylinder with double stroke with hand control.
  • Electrodes force adjustable by means of a protect built-in compressed air filter unit with gauge-pressure, with semi-automatic moisture discharging.
  • Electrodes speed regulators (both opening and closing), cylinder end-stroke shock absorber, and silencers for compressed air discharge assuring the minimum noise.


ITEMS 4625N-4626N

  • Arms gap 280 mm, arms depth 400 mm.

ITEMS 4629N-4630N

  • Adjustable arms gap from 170 to 500 mm, enabling to adjust the welder according to the work exigencies. Arms depth 500 mm.
