The CB is a control box which supplies power to the in the extraction arm integrated Working Light (WL) / automatic start/stop device (AST), extraction fan and optional automatic damper.
The CB arranges the extraction fan to switch on and off automatically. When the welding starts, the AST sends a signal to the CB. Subsequently, the extraction fan automatically switches on.
When the welding stops, the fan automatically switches off. Depending on the specific circumstances / the user’s wish, the initial delay and the run-out period of the fan can be adjusted.
The CB can also be used for connecting a stationary welding fume filter SFS. To be used in combination with one thermal relay (NTR) which is to be ordered separately. Up to 3kW.
