ArcOne ® Auto-Darkening filters protect against harmful ultra-violet and infrared rays. All shades have
maximum UV/IR protection. You can never burn your eyes due to optical radiation passing through the
filter. User’s eyes can be severely burned if welding with a damaged lens (cracked, pitted, etc.).
ANSI defines all welding helmets as secondary eye protection from optical radiation and impact. For
complete safety, primary protection, such as spectacles or goggles, should be used in conjunction with
welding helmets. Protective clothing and accessories such as leather bibs attached to the welding hel-
met will protect the user from spatter and optical radiation indirectly entering from areas behind the
helmet.
ACGIH (American Conference of Governmental Industrial Hygienists) has established a TLV-TWA of
5mg/m3 for welding fumes. Welding fumes cannot be classified simply. The composition and quantity
of both are dependent on the alloy being welded and the process and electrodes used.
Shade
Manually control dark shade with the shade knob located on the outside of the helmet. (See Figure 1)
Sensitivity and Delay
These filters have arc detection sensitivity and delay. Delay mode normally used in most welding applica-
tions except spot welding. Longer delay can be used at very low amps (<20A) to ensure filter stays dark.
4000V, 4500V, 5500V and 5000V: Change sensitivity with external analog control (See Figure 1). Press
Delay button +/- to change delay bars from 0.1 to 3.5 seconds (See Figure 2).
6000V: Change sensitivity with external analog control (See Figure 1). Press Delay button to change
delay bars from 0.1 to 2 seconds.
iDF81: Change sensitivity with external analog control. Sensitivity Level is not displayed on iDF81 LCD
readout. Press Delay button to change delay bars from 0.1 to 3.5 seconds (See Figure 3).
Grind Mode
4000V, 4500V, 5500V and 5000V: Turn the Sensitivity knob down until the LCD readout indicates Grind.
iDF81: Turn sensitivity knob counter-clockwise until it clicks and the LCD readout displays Grind.
(***NOTE: Other modes will not work when in Grind Mode).
Intelligent Darkening Filter (iDF) Modes
There are three modes: Normal, Auto-Variable, & iTig. Switch modes by Pressing AND Holding
down Mode button for two seconds. To Cycle modes continue depressing the Mode button.
