   * Start with a shade that is too dark to see the weld zone. Then, go to a lighter shade which gives a sufficient view of the weld zone without going below the minimum.

3. Sensitivity Control (Cut/Weld Mode): Use control to make the lens more responsive to different light levels in various welding/cutting processes. Use a Mid Range or 30-50% sensitivity setting for most applications. It may be necessary to adjust helmet sensitivity to accommodate different lighting conditions or if lens is flashing On and Off. Do not weld in the Grind mode; the lens will not darken.

   Recommended Sensitivity Settings

   	Setting
   Stick Electrode	Mid-Range
   Short Circuiting (MIG)	Low/Mid-Range
   Pulsed & Spray (MIG)	Mid-Range
   Gas Tungsten Arc (TIG)	Mid/High-Range
   Plasma Cutting	Low/Mid-Range
   Grind Mode	Grind Position-Far Right (Clockwise)

4. Lens Delay Control: The lens delay control is used to adjust the time for the lens to switch to the clear state after welding. The delay is particularly useful in eliminating bright after-rays present in higher amperage applications where the molten puddle remains bright momentarily after welding. Lens delay adjusts from min (0.1 second) to max (1 second).
5. TEST Button: Press the Test button to check if the lens is working properly. When the Test button is pressed, the lens should darken and return to the clear state. Do not use the helmet if the lens does not function as described.
6. Low Battery Indicator: The low battery indicator lights when 2-3 days of battery life remain. If battery power is low, replace with CR2450 lithium batteries.

3.3 Headgear Adjustment

1. Headgear Crown Adjustment: Made by adjusting for comfort and snapping the pins into the holes to lock securely in place.
2. Angle Adjustment: Adjusted by four pins on the right side of the headband top to provide adjustment for the forward tilt of the helmet. To adjust, loosen the right outside tension adjustment knob then lift on the control arm tab and move it to the desired position. Retighten tension adjustment knob.
3. Distance Adjustment: Adjusts the distance between the face and the lens. To adjust, loosen both outside tension knobs and press inward to free from adjustment slots. Move forward or back to desired position and retighten. (Both sides must be equally positioned for proper vision.)
