• Measure the earth connection between the hood and the
duct. The electrical resistance must be lower than 10 ohm.
ATTENTION!
If the electrical resistance is over 10 ohm, the litz
wire connection is not correct. In that case: make
sure that all litz wires from the hood to the duct are
interconnected.

• Make sure that the valve (ref. Fig. 5.1A/B) is open.
• Turn on the connected extraction fan or system.
• Start welding.
•
If desired, partly close the valve to adjust the airflow.
• When the welding position changes, move the hood to the
correct position in relation to the weld.
• Turn off the connected extraction fan or system approx. 20
