WH900V
The solar powered Auto-Darkening Welding Helmet is suitable for most welding applications. This helmet’s
1/30,000-second switch time automatically darkens the lens the moment you start welding. No matter what shade
the filter is set to, the UV/IR protection is always present.
ARC RAYS CAN INJURE EYES AND BURN SKIN
.
1. Before welding, always inspect helmet and auto-darkening filter (ADF) to be sure they are fitted properly and in
good condition.
2. Keep the sensors, solar cell, and filter lens clean. Clean the filter cartridge using a soapy water solution and a soft
cloth. Do not use solvents or abrasive cleaning detergent.
3. Do not weld in the overhead position while using this helmet.
4. Inspect the filter lens frequently and immediately replace any scratched, cracked, or pitted filter lens or
cover lens.
5. Always wear safety glasses or goggles under the welding helmet, and protective clothing to protect your skin
from radiation, burns, and spatter.
OPERATION:
HEADGEAR ADJUSTMENT
1. Adjust the headgear diameter with the twist knob on the back. Twist clockwise to tighten and counter-clockwise
to loosen.
2. Adjust the height by snapping the pin into the hole to lock securely in place.
3. To adjust the viewing angle, loosen the angle adjusting knobs on both sides of the helmet and change angle locker to
the desired tilt position. Once achieving the desired angle, tighten the knobs until snug. The helmet should still swing
up, but it should not drift downward when in place for welding.
4. To adjust the distance between the users face and ADF, loosen the distance adjusting knob on one side of the
helmet until the headband can move back and forth freely. Reposition the headband to one of the 3 slots, as desired.
Tighten the knob and repeat for the knob on the opposite side of the helmet. For proper auto-darkening filter
operation, both knobs should be positioned in the same slot. (If side one is in the middle slot, side two should be in
the middle slot.)

NOTES / NOTAS / REMARQUES
SHADE CONTROL
Select the shade DIN 9 to 13 based upon the welding process you will use by consulting the “Shade Guide Table”.The
variable shade control knob is for external adjustment. The welding helmet can also be used to protect the face when
cutting, using shade DIN 5 to 8. Grind mode DIN 4 prevents filter lens from auto-darkening for grinding use.
