The testing unit is suitable for the measurement and
display of closing forces on welding guns (C- and X-shaped).
The closing force of the welding gun is determined by the
force transducer, which absorbs the force of the gun
between the electrodes. Sensor and handle are
mechanically decoupled via a coil spring. The display
device connected by cable supplies the force transducer
with energy and displays the applied force directly in kN.
