When welding, select position welding on the welding filter cassette, and when grinding
select grind. When grinding, the welding filter cassette can be lifted up and the inside
clear polycarbonate plastic visor will give the needed protection.
Automatically darkening welding filter must be used with outer and inner protection
plates. The protection plates protect against heat, dirt, welding splashes and welding
spatter. The outer and inner protection plates must be replaced if they become scratched or
damaged in any way that impairs the view. The protection plates from Aketek are made of
polycarbonate plastic (PC) with a scratch-resistant surface coating. If protection plates are
not used, the welding filter cassette will be damaged by weld spatter and the warranty
will be invalidated.
4.1 The AIR blower unit has two levels of airflow: 170 l/min and 220 l/min. Press the ON
button to change the airflow. Turn off the AIR blower unit by pressing and holding down
the OFF button. Aketek LIFT-UP AIR has both visual and audible warnings when the
battery needs to be charged, when the filters need to be replaced and when the airflow is
too low. If the AIR unit warns, stop the welding work immediately and remedy the cause.
A clogged filter in the AIR unit makes the airflow too low. Periodically check the alarm for
low airflow, to make sure it works correctly. Have a fully charged battery, unblocked
filters, and a clean environment when you do that airflow check. To check the alarm, turn
on the AIR blower unit and keep one hand over the airflow outlet in the helmet or the
hose. Within 15 seconds you should hear the alarm and the red airflow lamp lights up.
Remove the hand. The alarm will turn off automatically when the blocking ceases.
4.2 When the AIR blower unit is running, the face seal gives an overpressure inside the
welding helmet, to minimize the leakage of contaminants. Make sure that the face seal fits
tightly around your head.
5.0 Maintenance and cleaning
Inspect the welding helmet regularly, both before and after use. Do not use the equipment
until any damaged or defective parts have been replaced, as this can affect the work
negatively. The welding filter cassette is sensitive to water.
5.1 The welding helmet must be handled with care. Do not leave it in a dirty
environment.
