TECNA 3184D Suspended MFDC Weld Gun

90 kVA | Air-Operated | MFDC / Inverter

TECNA 3184D MFDC Weld Gun

The TECNA 3184D is a 90 kVA, MFDC / inverter, air-operated, scissor-type spot weld gun. TECNA inverter technology offers advantages over single-phase AC, including greater welding quality and precision, more efficient use of electricity, smaller size, and less electrical loss due to impedance (power savings).

  • Model: TECNA 3184D
  • Gun type: Scissor-type
  • Power @ 50% duty cycle:  90 kVA
  • Power supply: MFDC / inverter
  • Max. weld current: 30,000 amps
  • Max. weld force: 2,427 lbs.
  • Max. electrode throat depth: 40.55 in.

    • Designed to carry out high-quality welds with high productivity and reduced installation costs.
    • High electrode force. Reduced dimensions and safe components.
    • Gyro suspension on sealed bearings assures, together with a balancer, 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.
    • The secondary circuit in copper is completely water-cooled.
    • Valves on the cooling circuit to make the electrode 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.

    Options:

    • Additional control handle.
    • Proportional valve. Allows to adjust the working pressure directly from the control unit and to combine a proper pressure value to each program. Assures constant and accurate working pressure.

    Additional equipment on demand:

    • Arms and electrodes: according to tables.
    • Different lengths of supply cables and hoses.
    • Balancers equipped with rotary and insulated hook (option RI).
