50kVA Linear Action Column Spot Welder c/w TE101 Control Unit – 400V

Key Features

  • Chrome-copper electrode holders designed for both straight and angled fittings, ensuring durability and suitability for heavy-duty service.
  • Transformer coated with water-cooled epoxy resin to prevent overheating and extend its lifespan.
  • Water-cooled arms, electrodes, and electrode holders for efficient heat dissipation during welding operations.
  • Microprocessor control unit TECNA TE101 for precise control and monitoring of the welding process.
  • USB port for data storage (only available with TE550 model), allowing for convenient storage and transfer of welding data.
  • Air-operated lubrication-free cylinder that eliminates oil mist, promoting a cleaner and safer working environment.
  • Protected filter assembly with gauge to ensure proper filtration and monitor the condition of the filter.
  • Two-stage electric foot control for clamping the welding pieces in the correct position before welding, enabling accurate and stable workpiece placement.
  • Pre-connected for an additional electric foot pedal, which allows for the direct recalling of welding program No.2. This feature is useful when different types of welding need to be performed on the same workpiece.
  • Arms with a gap of 280mm and adjustable depth of 320mm (Option 4638), providing flexibility and adaptability for various welding applications.
  • Adjustable electrodes stroke to achieve the maximum working rate, allowing for efficient and productive welding operations.

TECNA TE101 microprocessor-based welding control

The TECNA TE101 is a microprocessor-based welding control. The weld control is used to control the movement of the welder and the thyristor / silicon-controlled rectifier (SCR) that regulates the welding current. The working program followed by the TECNA TE101 is created through the 13 programming parameters available in the control. The TE 101 may be used for both manual and pneumatic-operated welders.


  • Synchronous thyristor drive with phase-shift control for welding current adjustment.
  • Built in ammeter (RMS value), 2 selectable ranges (18-56 kA).
  • Storing of 99 welding programs.
  • Inputs for external selection of 31 programs or 15 programs with parity control.
  • Welding times adjustment in half-periods.
  • Pre-weld, slope and pulse functions.
  • Welding current control limits. Error condition signalling output and function to stop welder operation.
  • Single and repeat operating mode. WELD/NO WELD function.
  • Welding current compensation function to assist welding of oxidised sheets and rods.
  • Possibility to connect two independent start of cycle device using different welding programs.
  • Auto retain disabling for manually actuated welders.
  • First phase shift delay adjustment. It enables the machine line current best balance.
  • Cos φ adjustment, allow to optimise current adjustment linearity.
  • End of cycle output for automation applications.
  • Thermostatic protection input.
  • Self-adjustment to the mains frequency 50/60 Hz.
  • Control of solenoid valve 24 Vdc 7,2 W max with short circuit protection.
  • Optional insulated RS 232 interface. Allow the connection with a printer or a personal computer for production data recording.
