4.4.2. Secondary rectifier

The heat sink transfer compound should spread in an even layer onto the heat sink. Then the card should
be immediately mounted onto the heat sink, this minimizes the possibility of any contamination (dirt etc.)
getting between the components.
The torx fixing screws in diodes are tightened to 1,2 Nm and the resistor (a smaller case than the diodes)
to 0,7 Nm.

4.5. Final testing

After the machine repair and low voltage tests, it is good practice to carry out some load tests and finish
with some test welds. Only then is it possible to guarantee the machine is working correctly.
