2.2 Operation
The CB-WCS is a control box which supplies power to the
connected welding cable sensor WCS and extraction fan SF
2400. The CB-WCS arranges the extraction fan to switch on
and off automatically. To realise this, the WCS is to be
connected to the ground cable of a welding machine. When
the welding starts, the WCS sends a signal to the CB-WCS.
Subsequently, the extraction fan SF 2400 automatically
switches on. When the welding stops, the fan automatically
switches off. Depending on the specific circumstances and/
or the user’s wish, the start delay and the stop delay of the
fan can be adjusted.
