Opening time delay adjustment: The opening time delay can be adjusted from 0.1 to 1.0 sec-
onds. It is recommended to use a shorter delay with spot welding applications and a longer delay
with applications using higher currents and longer welding intervals. Longer delay can also be
used for low current TIG welding in order to prevent the filter opening when the light path to the
sensors is temporarily obstructed by a hand, torch, etc.
Function welding/grinding (models Power GDS, Grand GDS only): For these filters, two modes
of operation can be selected: welding or grinding. By selecting the position »Grind«, the filter
switches off and it will not be triggered by the sparks generated during grinding. Before restarting
welding work, the knob should be set back to the »Weld« position.
