1-2.Arc Welding Hazards
Onlyqualified persons should install, operate, maintain, and repair this unit.
ARCRAYS can burn eyes and skin.
Arc rays from the welding process produce intense visible and invisible (ultravioletand infrared) rays that can burn eyes and skin. Sparks fly off from the weld.
Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when
welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). Refer to LensShade Selection table in Section 1-4.
Wear approved safety glasses with side shields under your helmet.Use protective screens or barriers to protect others from flash, glare, and sparks; warn
others not to watch the arc.
Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton,
and wool) and foot protection.
•Before welding, adjust the auto-darkening lens sensitivity setting to meet the application.
•Stop welding immediately if the auto-darkening lens does not darken when the arc is struck.
See the Owner’s Manual for more information.
WELDING HELMETS do not provide unlimited eye, ear, andface protection.
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.
Use impact resistant safety spectacles or goggles and ear protection at all times when using
this welding helmet.
Do not use this helmet while working with or around explosives or corrosive liquids.
Do not weld in the overhead position while using this helmet.
Inspect the auto-lens frequently. Immediately replace any scratched, cracked, or pitted cover
lenses or auto-lenses.
OM-256 016 Page 1
Page 4
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
Wear approved ear protection if noise level is high.
READ INSTRUCTIONS.
Read and follow all labels and the Owner’s Manual carefully before installing,
operating, orservicing unit. Read the safety information at the beginning ofthe manual and in each section.
Use only genuine replacement parts from the manufacturer.Perform maintenance and service according to the Owner’s Manuals, industry standards,
and national, state, and local codes.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing these fumes and gases can behazardous toyour health.
Keep your head out of the fumes. Do not breathe the fumes.If inside, ventilate the area and/or use local forced ventilation at the arc to remove welding
fumesand gases.
If ventilation is poor, wear an approved air-supplied respirator.Read and understand the Material Safety Data Sheets (MSDSs) and the manufacturer’s
instructionsfor metals, consumables, coatings, cleaners, and degreasers.
Workin a confined space only if it is well ventilated, or while wearing an air-supplied respirator.
Always have a trained watchperson nearby. Welding fumes and gases can displace air andlower the oxygen level causing injury or death. Be sure the breathing air is safe.
Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays
of the arc can react with vapors to form highly toxic and irritating gases.
Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the
coating is removed from the weld area, the area is well ventilated, and while wearing an air-suppliedrespirator. The coatings and any metals containing these elements can give off toxicfumes ifwelded.
1-3.Proposition 65 Warnings
Welding orcutting equipment produces fumes or gases which contain chemicals knownto the State of California to cause birth defects and, in some cases, cancer. (CaliforniaHealth &Safety Code Section 25249.5 et seq.)
Thisproduct contains chemicals, including lead, known to the state of California to causecancer, birth defects, or other reproductive harm. Wash hands after use.

SECTION 9 − MAINTENANCE
NOTICE− Never use solvents or abrasive cleaning detergents.NOTICE − Do not immerse the lens assembly in water.
The helmet requires little maintenance. However, for best performance clean after each use. Usinga soft cloth dampened with a mild soap and water solution, wipe the cover lenses clean. Allow to air
dry. Occasionally, the filter lens and sensors should be cleaned by gently wiping with a soft, dry cloth.

SECTION 10 − TROUBLESHOOTING
TroubleRemedy
Auto lens not On – autolens will not darken mo-mentarily when the Resetbutton is pressed.
Not switching – auto-lensstays light and will notdarken when welding.
Not Switching – auto-lensstays dark after the weldarc is extinguished, or theauto-lens stays dark whenno arc is present.
Sections of the auto-lensare not going dark, distinctlines separate the light anddark areas.
Switching or Flickering –the auto-lens darkens thenlightens while the weldingarc is present.
Check batteries and verify they are in good condition and installed
properly.
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 beendropped.Verify left and right battery trays are installed on thecorrect sides.
Stop welding immediately: Press the Auto On/Off button if lens isAuto-On type.
If power is On, review the sensitivity recommendations and adjustsensitivity.
Clean lens cover and sensors of any obstructions. Make sure thesensors are facing the arc; angles of 45 or more may not allowthe arc light to reach the sensors.
Fine-tune the sensitivity setting in small increments. In extremelight conditions, it may be necessary to reduce the surroundinglight levels.
Stop welding immediately: The auto-lens may be cracked whichcan be caused by the impact of dropping the helmet.
Weld spatter on the auto lens may also cause cracking. (The lensmay need to be replaced; most cracked lenses are not covered bywarranty).
Review the sensitivity setting recommendations and increase thesensitivity if possible. Be sure the arc sensors are not beingblocked from direct access to the arc light.
Check the lens cover for dirt and spatter that may be blocking thearc sensors. Increasing Lens Delay 0.1 − 0.3 second may alsoreduce switching.
Inconsistent or lighterauto-lens shading in thedark-state, noticeable onthe outside edges and cor-
ners.
Referred to as an angle of view effect, auto-darkening lenseshave an optimum viewing angle.
The optimum viewing angle is perpendicular or 90 to the surfaceof 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.
