Description
Available on:
CU 1200i Pro /MC, CU 1400i Pro /MC
Operating status on CU 1200i Pro /MC:
When welding starts, the cooling unit begins to operate, fan and
coolant pump run. The coolant pump regulates to a minimum
coolant flow of 1.0 l/min (0.26 gal./min [US]). When the coolant
temperature rises, the pump speed and the coolant flow rate are
automatically increased.
After the end of welding, the coolant pump and fans continue to run
for another 2 minutes subject to the return temperature. After these
2 minutes have passed, the fans and coolant pump are switched
off.
Operating status on CU 1400i Pro /MC:
The coolant pump starts to run when welding starts and is electron-
ically controlled subject to the coolant return temperature. The fans
start up at a return temperature of 40 °C (104 °F) and are electron-
ically controlled subject to the return temperature.
After the end of welding, the coolant pump and fans continue to run
for another 2 minutes subject to the return temperature. After these
2 minutes have passed, the fans and coolant pump are switched
off.
Recommended application
For high performance welding (maximum cooling power of the cool-
ing unit)
For energy-efficient cooling:
- Longer service life of the coolant pump
- Less soiling of the cooler in the cooling unit
- Lower noise emissions
- Reduced power consumption
