Operation Safety

Welding produces ultraviolet and infrared rays that are harmful if skin or eyes are left unprotected.

• Use a welding helmet that is supplied with the correct shade filter to protect your eyes and face while welding or watching a welding process. Refer to the Shade and Sensitivity charts on page 4

• Wear protective clothing that is fire resistant like leather or wool. DO NOT wear tennis shoes or street shoes while welding. Wear leather boots that come up past the ankles and have fire resitant soles.

• Protect those around you from welding flash and fire by using protective barriers or screens.

• Remove any flammable materials in the area before you begin to weld.

• Have someone perform fire watch while you are welding and for at least an hour after you have finished welding, to guard against fire.

• DO NOT weld if the welding helmet is dam aged. Inspect it carefully and replace compo nents as needed. Make sure the clear protec tive lense is not scratched or covered with smoke as it may impede the sensors, causing the auto darkening feature to malfunction and expose the operator.

• Never use the welding helmet to look at the sun. The welding helmet is designed for use while welding, only.

• DO NOT perform overhead welding using this welding helmet. Dripping metal could damage the auto darkening lense resulting in its malfunction, exposing the operator.

• DO NOT grind while wearing the helmet. The helmet and/or lense may become damaged and malfunction.

Adjusting the Headgear

The headgear supplied with your welding helmet can be adjusted for height, diameter, angle and friction during flip-down.

Height

1. Bend middle strap inward and press the bead

out of the hole.

2. Adjust the strap length until the sweat band is positioned just above your eye brows.

3. Snap the bead into the closest hole in the strap.

Diameter

1. Locate the hand knob on the back of the

headband. Rotate it clockwise to tighten and counterclockwise to loosen.

2. Place the helmet on your head and make adjustments to the headband until it is comfortably snug.

Flip-down Friction

1. Tighten or loosen the friction knobs located

on either side of the helmet to increase or decrease the amount of effort needed to raise and lower the helmet.

The headband and middle strap must be properly adjusted before ﬂ ipping the helmet down by nodding your head. If the headband is too loose, the helmet may tumble off after being ﬂ ipped down and the lenses could be damaged.

Angle

1. Looking at the back of the helmet, locate the

friction knob on the right hand side and loosen it 4 or 5 complete turns. It is not necessary to remove it completely.

2. On the side of the helmet and just below the friction knob are 3 holes. One of these holes will be occupied by a plastic pin. Push the pin in toward the inside of the helmet and position it over the desired hole.

3. Insert the pin and tighten the friction knob.

Choosing the hole furthest from the front of the helmet will allow the helmet to tilt further forward. Choosing the hole closest to the front will allow the helmet to tilt less.

Delay Time

This feature allows you to control how soon the auto lense reverts back to the #4 shade condition after you have stopped welding. This can be very important when the puddle remains very bright momentarily.

Figure 2. View of the inside control panel.

Sensitivity

You can control how sensitive the sensors are to the arc light. We recommend that the dial be set in the middle position for most applications.

Battery Compartment

The helmet uses 2 AAA size batteries which are installed in this compartment. If the helmet is to be stored for an extended time, remove the batteries to avoid damage to the compartment.

View Window

This window is set to #4 shade when off or when the sensors are not exposed to strong light.

Shade Dial

Adjustments can be made to the amount of shading the view window provides. The range is from #9 to #13 shade.

Figure 3. View of the left side of helmet.

"ON" Switch

Push this button once to turn on the auto darkening feature on the helmet. The helmet will turn off automatically 15 minutes after the sensors have been exposed to bright light.

Solar Cell

This unit powers some of the components used by the auto darkening device.
