AUTO-DARKENING FILTERFUNCTIONS
5-1. Selecting the Operating Mode
For some filters, two modes of operation can be selected: welding or grinding. (See Fig. 3)
Grind Mode: Used for metal grinding applications. In this mode the shade function is
turned off. The shade is fixed in the light state that allows a clear view to grind or weld
with the helmet providing face protection.
Weld Mode: Used for most welding applications. In this mode, the shade function is
turned on. When it optically senses a welding arc, please select a suitable shade level,
delay time and sensitivity as required.

or “MIN” (0.1 second) by using the infinitely dial knob. (See Fig. 6)
“MAX”(1.0second)–Longerdelayisformostweldingapplications,especiallyforhigh
amperage (current)applications;
“MIN” (0.1 second) – Shorter delay is for spot welding applications

path to the sensors is
temporarily obstructed by
a hand, torch, etc.
Grind mode is intended for grinding not for welding. Before restarting
welding,theknobshouldbesat backtothe“Weld”position.
