Description
Product Specification IRB 6600 M2000 53
Option 2088 Power unit, AC welding type HS
The basic power unit for type HS is equipped for a stationary / pedestal mounted
AC Spotwelding gun and with the following components:
- Cable gland for incoming power (X100)
- Circuit Breaker type ABB SACE, T1160 A
- Welding Timer and Thyristor type Bosch PST 6100.100L76kVA
- Fuse terminal for 24 V distribution
- Connector to Water and air unit, Modular Harting. (XS103)
- Connector to pedestal gun, Modular Harting (XS 104). (For process cables to
Stationary gun see option 2117, 2118 and 2119)
- Cable gland for outgoing power (X101). For power cable (see option 2095/
2096)
For further information see Installation and Maintenance manual, circuit diagrams and
separate manuals for the Bosch equipment.
Option 2090 MFDC welding S and HS
This option replaces the thyristor unit in option 2087 or 2088, with a MFDC inverter
type Bosch PSI 6100.100L. This option requires forced air cooling (option 2091).
Option 2091 Forced air cooling
This option adds a cooling fan with housing placed on the rear of the power unit. This
forces air on the cooling surface for the thyristor or MFDC converter. For the MFDC
converter this is mandatory. For the AC thyristor the need of the forced air cooling
depends on the load and the ambient temperature.
For further information see separate manuals for the Bosch equipment.
Option 2092 Earth fault protection
This option adds an earth fault protection to the circuit breaker. This protection could
be used for AC welding or MFDC welding. The sensitivity of the earth fault protection
could be adjusted. If and earth fault occurs the circuit breaker is tripped.
For further information see Installation and Maintenance manual, circuit diagrams and
separate specifications of the earth fault protection.
Option 2093 Contactor for weld power
This option adds a contactor with necessary wiring and relays inside the power unit.
This contactor could be used to disconnect power to the gun at for example tool change.
Option 2095 Weld power cable, 7m
This option includes floor cable of 7 m length for weld power. This is connected at
terminals inside the control cabinet and with an MC connector at manipulator base. The
cable has an allowed capacity of 150 A rms at + 20°C (68F) ambient temp and 120 A
rms at + 50°C (122F) ambient temp.
