5.1 Connecting an extraction element
For extracting the contaminated air - according to the intended use - the provided extraction element
(e.g. suction arm, suction hose, ...) must be connected at the suction nozzle (see chapter 2.1).
The assembly of a suction arm is described in the separate operating manual.
When using a detection element with extraction hood, the extraction hood must track the welding seam,
possibly taking advantage of the thermally induced welding fume movements.
However, it is important to ensure that connections between the workpiece and the
extractor hood (and generally between the workpiece and filter device) are avoided, so that, if
necessary, the welding current cannot flow back through the protective conductor of the filter
device to the welding machine.
5.2 Electrical connection
Electric malfunction possible in cause of an incorrect power supply.
Pay attention to the admissible supply voltage. Please observe the specifications on the type
plate.
● Reconnect the mains cable (see chapter 2.1) to the power supply.
● Make sure that the fan impeller rotates in the required direction when switching it on for the first
time. If not, it results in a low extraction capacity. For visual inspection, there is a sticker
attached to the bottom of the dust collecting housing (see chapter 2.1). For the connection
points of 400V and 500V the rotating field might be incorrectly set and must be changed, if
necessary. Briefly switch the device on and off. The fan slowly starts running and the rotation
direction can be compared to the sticker.
When the fan rotates in the wrong direction, the extraction capacity is
reduced.
