Operating Instructions

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this

manual including all text under subheadings therein before set up or use of this product.

Function

The Auto-Darkening Welding Helmet is designed to protect the eyes and face from sparks, splatter, and

harmful radiation under normal welding conditions. The Auto-Darkening Filter automatically changes from

a clear state to a dark state when an arc is struck, and it returns to the clear state when welding stops.

Before Welding

The Auto-Darkening Welding Helmet comes ready

for use. The only things you need to do before

welding are to remove the protective film from both

sides of the lens (if not already done), adjust the

position of the headband, select the correct shade

number for your application, and test the helmet

for proper operation as described following.
Check the Front Cover Lens to make sure that it is clean,

and that no dirt is covering the two sensors on the

front of the Filter Cartridge. Also check the Front/

Inside Cover Lens and the Front Lens Retaining Frame,

and make sure that they are secured in place.
Inspect all operating parts before each use for signs

of wear or damage. Any scratched, cracked, or

pitted parts should be replaced immediately before

using again to avoid severe personal injury.

Shade Number and Grinding Mode Selection

1. Select the shade number you need (see Shade

Guide Chart on the previous page) by turning

the Shade Control Knob. Be sure that the

shade number of the Welding Helmet is the

correct shade number for your application.

Note: If a selection of shades are recommended

for your application, try the darkest setting first.

3. The shade number can be set from 9 to 13 by

turning the Shade Control Knob until the arrow

points to the desired shade number. See Figure B.

4. Remember to check with the Shade Guide

Chart on the previous page to determine the

proper shade number for your application.

5. Important Note: Test the helmet auto-darkening

filter lens before welding. While wearing the

helmet, briefly strike an arc, keeping your face

and eyes turned slightly away, and to one

side. The lens should darken evenly when not

directly facing the arc. If it does not darken

properly, do not use the Welding Helmet.

Grind Mode Setting

To change to Grinding Mode, rotate the

Shade Control Knob counterclockwise to

Grind. This turns off the shade function so

the helmet lens stays clear. Use this function

to provide protection while grinding.

CAUTION! Set the helmet to the proper

shade setting before welding again.
