Option 788-1 Forced air cooling
Offers a cooling fan with housing placed on the rear of the Spot Welding cabinet
which forces air on the cooling surface/grids of the thyristor or MFDC inverter (see
pictures below). Cabling to the fan goes via a cable gland at the rear of the Spot
Welding cabinet. The fan runs continuously when the welding system is powered up.
The fan is required to be used together with Bosch MFDC (option 782-7). For the
AC options (option 782-1 and -2) the need will depend on the welding conditions and
surrounding temperature.

Option 789-1 Earth fault protection unit
Offers an earth fault protection integrated with the circuit breaker for the weld power.
This protection could be used for AC welding or MFDC welding. The sensitivity of
the earth fault protection could be adjusted. If an earth fault occurs the circuit breaker
is tripped.
