TECNA MFDC Weld Gun Features

  • Designed for carrying out high quality welds with high productivity and reduced installation costs.
  • High electrodes force. Reduced dimensions and safe components.
  • Gyro suspension on sealed bearings, assuring, together with a balancer, an accurate maneuverability at any degree.
  • Rotation locking device.
  • Long working stroke to weld reinforcements, ribs, and to enable working in areas difficult to reach etc.
  • Adjustable working stroke for heavy duty.
  • Temporary extra stroke to reach the areas to be welded.
  • Chromium-plated cylinder and shaft for heavy duty and long life.
  • Lubrication free pneumatic circuit to avoid oil mist in the environment.
  • Secondary circuit in copper completely water-cooled.
  • Valves on the cooling circuit to make the electrodes replacement easier.
  • Supplied equipped with earth leakage switch with 30 mA safety control. Upon request ground fault unit.
  • Control handle enabling the selection of two welding programs as well as the opening of the double stroke and the function “pressure only”.
  • Safety device against accidental triggering.
  • Emergency push-button to stop the machine immediately.
  • Flow-switch which makes the welder stop if the cooling water does not circulate.
