SAFETY

• WARNING! This helmet is not suitable for use with laser welding or CUTTING or for overhead welding applications.

• Ensure all workshop safety rules, regulations and conditions are complied with when using welding equipment. The helmet will not offer protection against misuse of workshop tools, equipment, or accessories.

• Maintain the helmet in good condition and protect cartridge from liquid and dirt contact. Regularly replace the protective lens and replace any damaged or worn parts. Use genuine parts only. Unauthorized parts may be dangerous and will invalidate the warranty.

• Ensure the front cover window is securely in place before use.

• Fit the helmet and adjust the head band so the helmet will sit as low and near to your face as possible.

• Use helmet only in temperatures ranging from -5°C to 55°C.

• Remove ill fitting clothing, remove ties, watches, rings and other loose jewellery.

• Maintain correct balance and footing.

• Ensure the floor is clear from obstructions, not slippery and wear non-slip protective shoes.

• Keep children and unauthorised persons away from the working area.

• WARNING! The helmet will only protect the eyes and face from radiation and sparks. It will not protect against explosive devices or corrosive liquids.

• DO NOT use helmet for any purpose for which it is not designed.

• DO NOT use helmet unless you have been instructed in its use by a qualified person.

• DO NOT open or tamper with the shade cartridge.

• DO NOT get the helmet wet or use in damp or wet locations.

• DO NOT leave work place with helmet in lowered position, as bright light source may darken cartridge unexpectedly.

• DO NOT place the helmet on a hot surface.

• DO NOT use helmet without front cover window fitted. To do so will invalidate your warranty.

• Clean helmet (see section 5.5) and store the helmet in a safe, dry, childproof location.

• WARNING! Before welding always inspect the cartridge filter to ensure that it is not damaged. To test the filter prior to welding,direct the front of the cartridge filter to a bright light source which will cause the lens to darken. Then using your hand rapidly cover and uncover the sensor. The filter should lighten momentarily then return to a dark state.

• WARNING! DO NOT use the helmet if damaged or you suspect it may be faulty. (Contact Sealey Stockist).

• DANGER! DO NOT use if, at any time, the face plate in the cartridge FAILS to darken when exposed to a welding spark. Remove cartridge and return to your Sealey stockist for checking.

• Continued use of the product knowing that the auto darkening feature is NOT FUNCTIONING may DAMAGE YOUR EYES and CAUSE BLINDNESS.

• DANGER! DO NOT wear this respirator system to enter areas where:

  •  Atmospheres are oxygen deficient.
  • Contaminant concentrations are unknown.
  • Contaminant concentrations are Immediately Dangerous to Life or Health.
  • Contaminant concentrations exceed the maximum use concentration determined using the assigned Protection Factor for the specific respirator system.

• WARNING! The Particle filter can not be cleaned. DO NOT attempt to remove contamination using for example compressed air as this will destroy the filters, the equipment will not give the expected protection and the warranty will be invalidated.

• If ventilation is poor, wear an approved air-supplied respirator.

• Read and understand the Material Safety Data Sheets and the manufacturer’s instructions for metals, consumables, coatings, cleaners, and degreasers.

• Work in confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watch- person nearby. Welding fumes and gases can displace air and lower 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 vapours 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-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded. RESPIRATOR (PAPR) MISUSE can be hazardous. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.

• Read and follow these instructions and the safety labels carefully. The powered air purifying respirator (PAPR) helps protect the user from specific airborne contaminants but must be used correctly to be fully effective. Have an industrial hygienist test the air in your facility to ensure the PAPR provides adequate protection from contaminants in your environment. If you have questions about the respirator, see equipment warning label and consult your Safety Director and a certified Industrial Hygienist.

• Follow all applicable EN/ANSI/CSA/AS &NZS, and other regulatory guidelines pertaining to the use of respirators.

• DO NOT use the powered air purifying respirator where there is danger of fire or explosion.

• DO NOT use the powered air purifying respirator in windy conditions or negative pressure inside the hood may draw in contaminants from the outside air.

• DO NOT use the powered air purifying respirator without a properly installed spark guard cover. Without the spark guard cover, welding sparks may ignite the filter, or damage the filter and allow unfiltered air into the helmet.

• The powered air purifying respirator does not supply oxygen. Use the respirator only in atmospheres for which it is EN/ANSI/CSA/ AS &NZS approved. DO NOT use the respirator where oxygen levels are 19.5% or lower, where contaminant levels are unknown or are immediately dangerous to life or health, or where the contaminant levels exceed the respirator specifications.

• DO NOT enter a hazardous area until you are sure the respirator equipment is correctly assembled, working properly, and properly worn.

• Before each use, inspect the respirator equipment for damage and verify it operates properly Before using the respirator, test air flow to verify it is providing an adequate volume of air.

• DO NOT use the powered air purifying respirator without all filter components or with the blower turned off, as hazardous levels of oxygen and carbon dioxide may accumulate in helmet.

• Always wear the powered air purifying respirator when entering a contaminated area. DO NOT remove the respirator until outside the contaminated area.
  Dangerous contaminants may not smell or be visible. Leave the area immediately if you notice the following:

  • Breathing becomes difficult.
  • You experience dizziness, impaired vision, or eye, nose, or mouth irritation.
  • The powered air purifying respirator alarm sounds.
  • The equipment is damaged.
  • Air flow decreases or stops.
  • If you think the equipment is not supplying adequate protection.

• DO NOT r emove the equipment until you are in a safe area.

• DO NOT repair, modify, or disassemble the powered air purifying respirator or use with parts or accessories not supplied by the manufacturer. Use only those components that are part of the approved assembly.

• Replace damaged or clogged filters. DO NOT wash or reuse filters. DO NOT clean filters by tapping or with compressed air or filter elements may be damaged. Dispose of used filter elements according to local, state, and federal requirements.

• The powered air purifying respirator must be used with the helmet, hood, and filters recommended by the manufacturer to provide a respirator system. See the label on the blower for information on the required equipment.

• DO NOT use the powered air purifying respirator belt or shoulder straps(if equipped) as a safety harness.

OPERATION

• ADJUSTING THE HELMET

  • Adjust the headgear diameter with the twist knob on the back. The knob is locked until pushed in. Once unlocked, twist clockwise to tighten and counter clockwise to loosen.
  • Adjust the height by snapping the pin on the top band into the hole to lock securely in place.
  • To adjust the viewing angle, loosen the knob on both sides of the helmet and change angle locker to the desired tilt position (5 selection and positioned in the middle by default). Once achieving the desire angle, tighten the knobs until snug.
  • The helmet should still swing up, but it should not drift downward when in place for welding.
  • To adjust the distance between the user’s face and ADF, loosen the knobs on both sides of the helmet until the headband can move back and forth freely, reposition the headband at one of the 3 slots as desired (The headband is positioned in the middle by default). This should be done one side at a time and both sides should be located at the same position for proper auto-darkening filter operation.

• SHADE GUIDE TABLE

• SELF-CHECK

  • Press the TEST Button at any time to see if it automatically switches to dark state and release it to check that the filter returns to the light state. Shade Control; Select the shade DIN 9 to 13 based upon the welding process you will use by consulting the “Shade Guide Table”. The variable shade control knob is for internal adjustment. The welding helmet can also be used to protect the face when cutting, from shade DIN 5 to 8. Grind mode DIN 4 prevents filter lens from auto-darkening for grinding use.

• SENSITIVITY CONTROL

  • The sensitivity can be set from LOW to HIGH by using the sensitivity dial. The LOW setting suits excess ambient light or with another welding machine close by. The HIGH setting suits low amperage welding and welding in areas with low light conditions, especially low amperage argon arc welding. Selections between LOW and HIGH  are suitable for most of indoor and outdoor welding
    operations.

• DELAY CONTROL
  When welding ceases, the viewing window automatically changes from dark back to light but with a pre-set delay to compensate. The delay time can be set from MIN (0.1 sec) to MAX (1.0 sec), by Shade Delay Control The minimum delay suits spot or short welds. The maximum delay suits heavy current welding and reduces eye fatigue from the arc. Selections between MIN and MAX are suitable for most of indoor and outdoor welding operations.
