ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld.
WELDING HELMETS do not provide unlimited eye, ear and face protection.

The helmet features a flip-up auto-darkening lens and a separate, clear grinding shield. Flip the lens up when grinding and performing other non-welding work. Flip the lens down when welding or cutting.
The auto-darkening lens turns on (darkens) automatically when welding begins and turns off 3 minutes after welding stops.
(No. 5-9/9-13)
Variable Shade Control Button (No. 5-9/9-13)
Use the Shade adjustment buttons to adjust the lens shade in the darkened state. Use the table in Section 1-4 to select proper shade control setting based on your welding process.
The shade ranges for each mode are as follows:
Weld: No. 9 - No. 13
Cut: No. 5 - No. 9
Grind: No. 4 only
Start at the highest setting and adjust lighter to suit the application and your personal preference.
Variable Shade Adjustment Procedure
Press Mode button to select the mode appropriate for the work activity. Helmet control display will appear.
Press Mode Button to select desired function: Weld, Cut, or Grind. Use Shade adjustment button to select desired shade. Begin welding or continue with other lens adjustments.
Weld Mode — used for most welding applications. In this mode the lens turns on when it optically senses a welding arc. Adjust shade, sensitivity, and delay settings as needed
Cut Mode - used for cutting applications. In this mode the lens turns on when it optically senses a cutting arc. Adjust shade, sensitivity, and delay settings as needed.
Grind Mode —used for metal grinding applications. In this mode the shade is fixed shade No. 3. No lens adjustments are possible
Reference: ANSI Z49.1:2005
*Start with a shade that is too dark to see the weld zone. Then, go to a lighter shade which gives asufficient view of the weld zone without going below the minimum.
Recommended Sensitivity Settings | |
Stick Electrode | Mid-Range |
Short Circuiting (MIG) | Low/Mid-Range |
Pulsed & Spray (MIG) | Mid-Range |
Gas Tungsten Arc (TIG) | Mid/High-Range |
Plasma Arc Cutting/Welding | Low/Mid-Range |
Grind Mode | Grind Position - Far Right (Clockwise) |
There are four headgear adjustments: headgear top, tightness, angle adjustment, and distance adjustment.
Never use the auto-darkening lens without the inside and outside lens covers properly installed. Welding spatter will damage the auto-darkening lens and void the warranty.
Rotate both retaining clips to the Open position.
Gently push shield toward bottom tab and remove shield from helmet.
Remove retaining clips from shield. Install clips in same location on new shield (Retaining clips are not interchangeable.)
Install new shield in helmet and rotate clips to the Lock position
Never use the auto-darkening lens when the inside and outside lens covers are not properly installed. Welding spatter will damage the auto-darkening lens.
Outside Lens Cover
Remove lens holder by pulling the holder away from the helmet on either side of lens holder. Remove lens cover from shell by pulling top cen ter of lens. Replace lens cover in lens holder by placing one edge in place, bending lens cover, and inserting opposite edge into lens holder channel. Re install lens holder in helmet.
Inside Lens Cover
Remove the inside lens cover by pulling top center of lens cover from lens holding channels. Replace the lens cover by gently bowing it in the center and inserting it, one end at a time, into the lens holding channels.
Auto-Darkening Lens
Remove lens holder and outside lens cover using instructions above Press up on lens release tab and push auto darkening lens assembly from the inside to remove. Replace the lens by aligning it on the release tabs and pressing it in until it snaps into place.
Trouble | Remedy |
Auto lens not ON — autolens will not darken momentarily when the Reset button is pressed. | Check batteries and verify they are in good condition and installed properly. Also, check battery surfaces and contacts and clean if necessary. Check battery for proper contact and gently adjust contact points if necessary. This is particularly important if the helmet has been dropped. Verify left and right battery trays are installed on the correct sides. |
Not switching auto-lens stays light and will not darken when welding. | Stop welding immediately: Press the Reset button if lens is Auto-On type. If lens is Manual-On type, make sure the lens is turned On. If power is on, review the sensitivity recommendations and adjust sensitivity. Clean lens cover and sensors of any obstructions. Make sure the sensors are facing the arc; angles of 45° or more may not allow the arc light to reach the sensors. |
Not Switching —auto-lens stays dark after the weld arc is extinguished, or the auto-lens stays dark when no arc is present. | Fine-tune the sensitivity setting by making small adjustments to the control by turning it toward the "min" setting. In extreme light conditions, it may be necessary to reduce the surrounding light levels. |
Sections of the auto-lens are not going dark, distinct lines separate the light and dark areas. | Stop welding immediately: The auto-lens may be cracked which can be caused by the impact of dropping the helmet. Weld spatter on the auto lens may also cause cracking. (The lens may need to be replaced; most cracked lenses are not covered by warranty). |
Switching or Flickering — the auto-lens darkens then lightens while the welding arc is present. | Review the sensitivity setting recommendations and increase the sensitivity if possible. Be sure the arc sensors are not being blocked from direct access to the arc light. Check the lens cover for dirt and spatter that may be blocking the arc sensors. Increasing Lens Delay 0.1 - 0.3 second may also reduce switching. |
Inconsistent or lighter auto-lens shading in the dark-state, noticeable on the outside edges and corners. | Referred to as an angle of view effect, auto-darkening lenses have an optimum viewing angle. The optimum viewing angle is perpendicular or 900 to the surface of the auto-lens. When that angle of view varies in the dark-state, welders may notice slightly lighter areas at the outside edges and the corners of the lens. This is normal and does not represent any health or safety hazard. This effect may also be more noticeable in applications where magnifying lenses are used. |
