FK 4000 auto-
transformer
This option is available for the following devices:
- FK 4000 R
- FK 4000 Rob
- FK 4000 R FC
The FK 4000 and FK 4000 R US cooling units are equipped with the FK 4000 auto-trans-
former option as standard.
- The FK 4000 auto-transformer is required if the cooling unit must be operated using a
multivoltage power source (MV). The multivoltage power source has an input voltage
of 3 x 200 - 240 V / 3 x 380 - 460 V (+/- 10%)
- The FK 4000 auto-transformer converts this voltage from the power source into what
the cooling unit needs
FK 4000 R flow
sensor with cool-
ant filter
This option is available for the following devices:
- FK 4000 - only if the interconnecting hosepack does not exceed a length of 5 m (16 ft.
5 in.)
- FK 4000 R
The FK 4000 R US, FK 4000 R FC and FK 4000 Rob cooling units are fitted with the flow
sensor with coolant filter option as standard.
How it works:
- The option monitors the coolant flow during welding
- If the coolant flow falls below 0.7l/min (0.18 gal./min), "no | H2" is automatically dis-
played, the welding current is interrupted and the cooling unit switches off
- If the welding system has a Comfort or WeldProcessData (OPC Fronius LocalNet
server) control panel, the coolant flow can be shown on it
- To display the coolant flow value, press the F3 parameter selection / indicator key
on the Comfort control panel
A disruption in the coolant flow can occur as a result of:
- Insufficient coolant
- Contaminated coolant
- Leaks in the cooling circuit
- Faulty coolant pump
- Frozen coolant (welding at too low a temperature)
Thermostat This option is available for the following devices:
- FK 4000
- FK 4000 R
- FK 4000 R FC
- FK 4000 R US
