Tecna 50 Kva Spot Welder (Pneu/Micro Processor Control) 4663

-29% Tecna 50 Kva Spot Welder (Pneu/Micro Processor Control) 4663

Industrial quality 50 kVA pneumatic resistance spot welder with microprocessor control for high production work.


This heavy-duty machine is equipped with a water cooled transformer with epoxy resin coated windings, a two stage electronic foot control and water-cooled arms, electrodes and holders.   


  • Pneumatic spot welder with TE90 microprocessor welding control unit. 
  • Optional TE 550 constant current control unit. 
  • 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.
  • Double effect pneumatic cylinder, lubrication free against oil mist.
  • 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.
