Components of the Power Unit
8.1
Main Assemblies
1- Charging unit
A - Welding circuit
2 - Control
3 - Welding capacitors
4 - Welding thyristor
Via the
charging unit (1)
the
welding capacitors (3)
are loaded to the set voltage.
The capacitors store the energy which is required for the welding process.
The
electronic switch (4)
releases the charging voltage in the right time.
The charging process as well as the welding process are controlled by the
control
unit (2)
.
The positive pole of the capacitoris is connected via the thyristor with one side of the
welding gun. The negative pole is connected to the other side of the welding gun.
The type plate is located on the backside of the power unit.
