• Signal horn (Pos. 6)
Reliable capture of welding fumes is only possible with sufficient extraction
capacity. As the dust accumulation in the filter increases, its resistance to through-
flow increases and the suction decreases.
As soon as it drops below a minimum value, the signal horn will sound.
Now, a change of filter is required.
The same happens if the damper flap in the exhaust hood is closed too far and
the extraction capacity is reduced too much.
This situation can be remedied by opening the damper flap.
• Connection socket for start-stop sensor (Pos. 7)
An optional start-stop sensor can be connected here. Its use means that the
extraction system will only operate during the pure welding time (arcing time)
plus the set run-on time. The start-stop sensor is automatically detected by the
device.
• Pressure switch(Pos.8)
May only be used by manufacturer service department.
