3-5. Sensitivity Control

1 Sensitivity Control

Weld Mode

Use control to make the lens more respon- sive to different light levels in various weld- ing processes. Use a Mid-Range or

130−50% sensitivity setting for most ap-

plications.

 

It may be necessary to adjust helmet sensi-

 

 

tivity to accommodate different lighting con-

 

 

ditions or if lens is flashing On and Off. Ad-

 

 

just

helmet sensitivity as follows:

 

 

. Adjust helmet sensitivity in lighting con-

 

 

 

ditions helmet will be used in.

 

 

S

Turn sensitivity control to lowest

 

 

 

setting.

 

 

S

Press Reset button to turn helmet On.

 

 

 

Helmet lens will darken twice and then

 

 

 

clear.

 

 

S Face the helmet in the direction of use,

 

 

 

exposing it to the surrounding light con-

 

 

 

ditions.

 

 

S Gradually turn sensitivity setting clock-

 

 

 

wise until the lens darkens, then turn

 

 

 

sensitivity control counterclockwise

 

 

 

until slightly past setting where lens

 

 

 

clears. Helmet is ready for use. Slight

 

 

 

readjustment may be necessary for

 

 

 

certain applications or if lens is flashing

 

 

 

on and off.
