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:

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

‰ WARNING! The Particle filter cannot 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 a 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 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-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 the 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 a 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 airflow 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 the 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.
– Airflow decreases or stops.
– If you think the equipment is not supplying adequate protection.
DO NOT remove the equipment until you are in a safe area.
DO NOT repair, modify, or disassemble the powered air purifying respirator or use it 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.

HELMET

4.1. HELMET ADJUSTMENT (fig.1)
4.1.1. To adjust the fit-to-head, use the handwheel (fig.1.1) on the back of the strap to increase or decrease the headband circumference.
4.1.2. Further adjustment for fit-to-head can be achieved by increasing or decreasing the length of webbing straps fig.1.2 and fig.1.3.
4.1.3. To adjust the distance between the user’s face and the front of the mask, loosen the side thumbwheels and depress the spring-loaded pin on the hinge points (fig.1.4, fig.1.5). Slide the helmet to the desired position and release the pin. There are three locations into which the spring-loaded pin may be seated. Re-tighten the thumbwheels. 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.
4.1.4. To adjust the viewing angle loosen the side thumbwheels. Depress the tab on item fig.1.6 to disengage it from the rotation lock (fig.1.7) and set the angle to suit. There are several locations on the rotation lock into which the tab may be engaged. Re-tighten the thumbwheels.

4.2. SHADE GUIDE TABLE

4.3. CONTROLS (fig.2)

4.4. SHADE VALUE
4.4.1. The shade value ranges are divided into two sections ( 5-8 or 9-13). The shade range can be set to either 5 – 8 or 9 – 13 using the selector switch (fig.2.1).
4.4.2. The shade value can be set using the control dial (fig.2.2). Check the shade guide table (above) to determine the proper shade number for your application. The shade goes darker from 5 to 8 or from 9 to13.
4.5. SENSITIVITY CONTROL
4.5.1. The sensitivity can be set from LOW to HIGH by using the sensitivity control dial (fig.2.5). 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.
4.6. DELAY CONTROL
4.6.1. 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 (0.2 sec) to MAX (1.0 sec), by shade delay control (fig.2.4). 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.
4.7. GRINDING
4.7.1. To select between grinding and welding, set the Grind/Weld select switch (fig.2.3) to “GRIND”.
NOTE: It is important to return this switch to the WELD position when the grinding operation is completed.
