Auto Darkening  
Welding Helmet  
MODEL H7786  
INSTRUCTION SHEET  
Wear safety glasses with sides shields or  
goggles under the welding helmet.  
Wear protective clothing that is fire resistant  
like leather or wool. DO NOT wear tennis  
shoes or street shoes while welding. Wear  
leather boots that come up past the ankles  
and have fire resitant soles.  
Welding helmets do not provide unlimited  
protection for your eyes, ears and lungs.  
Personal injury could result from using  
this welding helmet without proper protec-  
tive gear. Always wear safety glasses, an  
approved respirator, and hearing protection  
while welding.  
Protect those around you from welding  
flash and fire by using protective barriers or  
screens.  
Remove any flammable materials in the area  
before you begin to weld.  
Have someone perform fire watch while you  
are welding and for at least an hour after you  
have finished welding, to guard against fire.  
Introduction  
This Auto Darkening Welding Helmet features a  
reaction time of 2ms, 2 sensors, variable shades  
from 9-13, adjustable delay from 0.1-1.0 seconds,  
DO NOT weld if the welding helmet is dam-  
aged. Inspect it carefully and replace compo-  
nents as needed. Make sure the clear protec-  
tive lense is not scratched or covered with  
smoke as it may impede the sensors, causing  
the auto darkening feature to malfunction and  
expose the operator.

Never use the welding helmet to look at the  
sun. The welding helmet is designed for use  
while welding, only.  
Operation Safety  
Welding produces ultraviolet and infrared rays that  
are harmful if skin or eyes are left unprotected.  
DO NOT perform overhead welding using  
this welding helmet. Dripping metal could  
damage the auto darkening lense resulting in  
its malfunction, exposing the operator.  
Use a welding helmet that is supplied with  
the correct shade filter to protect your eyes  
and face while welding or watching a welding  
process. Refer to the Shade and Sensitivity  
charts on page 4.  
DO NOT grind while wearing the helmet. The  
helmet and/or lense may become damaged  
and malfunction.

Delay Time  
D
This feature allows you to control how soon the  
auto lense reverts back to the #4 shade condition  
after you have stopped welding. This can be very  
important when the puddle remains very bright  
momentarily.

E
Sensitivity  
You can control how sensitive the sensors are to  
the arc light. We recommend that the dial be set in  
the middle position for most applications.  
Battery Compartment  
The helmet uses 2 AAA size batteries which are  
installed in this compartment. If the helmet is to be  
stored for an extended time, remove the batteries  
to avoid damage to the compartment.

Operation  
Sensitivity Dial  
"ON" Switch  
As previously mentioned, the auto darkening  
lense can be made more sensitive or less sensi-  
tive to bright light produced by welding. In most  
applications, the dial should be set to middle of its  
range. However, the setting should be changed  
when used in extreme conditions. Below is a list  
of applications and settings that you can use as a  
guide for making adjustments.  
Push the "ON" button on the side of the helmet.  
The auto darkening feature will activate and stay  
active for 15 minutes after the last bright light.  
You will need to push the button again when this  
occurs. Before welding raise the helmet up to a  
bright light source and make sure the auto dark-  
ening feature activates. If it does not, push the  
button and check again. If it still does not work  
see the troubleshooting guide at the end of this  
instruction sheet.

Maintenance  
Batteries  
Lens Cover  
To replace the batteries, unclip the cover on  
the battery compartment. Be sure to orient the  
replacements as described on the compartment  
cover or damage could occur to the electronics  
in the helmet. Remove the batteries for long term  
storage of the helmet.  
The lens cover must be clean to insure the proper  
and safe operation of the auto darkening feature.  
We recommend that the lens cover be removed  
and that it be cleaned with warm soapy water  
and a soft cloth. Paper towels, solvents and some  
glass cleaners will damage the lens cover, reduc-  
ing its effectiveness and safe operation. Replace  
damaged lens covers.
