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 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 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.
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.
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 1. Remember to check with the Shade Guide Chart on the previous page to determine the proper shade number for your application.
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.
