a As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas welding, cutting, or brazing where the torch and/or the flux produces a high yellow light, it is desirable to use a filter lens that absorbs the yellow or sodium line of the visible light spectrum.

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.

Solar Cells
This Welding Helmet utilizes high performance solar cells as its power supply, and has a replaceable 3V CR2450 lithium battery as power backup.

Shades
User-selectable variable shades from 5 to 9 and 9 to 13 are adjusted with the Set Switch, Set Switch, and Range Switch. This product is in full conformity with related DIN, ISO, EN379 safety standards and ANSI Z87.1-2020 standard.

Filters
The ultra high performance of UV and IR Auto-Darkening filters provides the user’s eyes and face with full protection against UV and IR radiation during the entire welding process, even in clear state. The UV/IR protection level is up to shade 15 at all times.

Magnifying Cheater Lens
To attach a magnifying cheater lens (sold separately) to the inside of the helmet, slide the cheater lens into place underneath the tabs located on the lower right and left sides of the Lens Retaining Frame.

Before Welding

Important: Make sure battery is properly installed before first use. Helmet is shipped with one CR2450 Lithium Battery.
The Auto-Darkening Welding Helmet comes ready for use. Prior to first use, remove the protective film from both sides of the Front Lens Cover and Inside Lens Cover (if not already done). Check the Front Lens Cover to make sure that it is clean, and that no dirt is covering the four sensors on the front of the Auto Darkening Filter Cartridge. Also check the Inside Lens Cover and the Lens Retaining Frame, and make sure that they are secured in place.
Adjust the position of the headband, select the correct shade number for the welding application, and test the helmet for proper operation as described below.
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.
