Opening time delay adjustment:
The opening time delay can be adjusted from 0.2 to
0.8 seconds. 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. Long-
er delay can also be used for low current TIG welding in order to prevent the filter open-
ing when the light path to the sensors is temporarily obstructed by a hand, torch, etc.
