Before First Use 1. The Auto-Darkening Welding Helmet needs to be charged prior to use and after extended storage. Leave the solar panel on the helmet facing the sun for at least 4 hours before first use. 2. Remove the protective film from both sides of the front lens (if not already done). 3. Follow the Before Each Use instructions below. Before Each Use 1. Check the Front Lens Cover to makes 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 Lens Cover and the Front Lens Retaining Frame, and make sure that they are secure in place. Check for light tightness before each use. 2. 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. 3. Select the shade number you need for your setting at the turn of a shade knob - see chart below. Finally, 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.

Adjust headband so that the helmet is seated on the head as low as possible and close to your face. Adjust helmet’s angle when in the lowered position by turning the adjustable limitation washer. 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. Product Features/Operation At the moment the welding operation is started, the filter screen automatically changes from clear to dark in only 1/25,000th of a second. Dark to clear delay adjustment: Operator can vary the time for the filter to return to clear state. At the moment welding is stopped, the filter screen automatically changes from dark to clear state according to the time setting you select. Switch Sensitivity Adjustment: The operator can adjust the amount of light needed to cause the Lens to darken. This Welding Helmet utilizes high performance solar cells as power supply, and has built-in battery(ies) as power backup, see below. Under normal welding conditions, users can expect a battery lifetime of more than 6 years. User-selectable (DIN) variable shades from 9 to 13 are adjusted at the turn of a shade knob (shade variable). This product is in full conformity with related DIN, ISO, EN379 safety standards and ANSI Z87.1-1989 standard. The ultra high performance of UV and IR Auto-Darkening filters provides to the user’s eyes and face full protection against UV and IR radiation during the entire welding process, even in the clear state. The UV/IR protection level is up to Shade 16 (DIN) at all times. Models 94336 & 94337 (View from inside of helmet.) Battery Cover Low Battery Light Sensitivity Adjustment Adjusts the amount of light the lens requires to respond and darken with. Dark to Clear Delay Adjustment Adjusts the amount of time until the lens turns back to clear. These models include one built-in 3V CR2450 battery. Low Battery Light will illuminate when replacement is needed. Models 91212 & 91214 (View from inside of helmet.) Dark to Clear Delay Adjustment In FAST Position = .25-.35 Second In SLOW Positio...
