WELDING HELMETS WITH AUTOMATIC DARKENING FILTER.
NB: In the text that follows, the term “helmet” and “filter” will be used.

1. GENERAL SAFETY FOR HELMET USE AND PROFESSIONAL AND INDUSTRIAL USE

The operator must be sufficiently trained on safe use of the welding machine and informed on the risks relating to arc welding procedures, the relevant safety measures and the emergency procedures.

• During welding, luminous radiation emitted by the electric arc can damage eyes and burn skin; furthermore, welding produces sparks and drops of molten metal can be projected in all directions. It is therefore necessary to use the safety helmet to avoid physical injury, which may even be serious.

• Avoid the welding helmet catching fire, for any reason, as the fumes produced are harmful to eyes and, if inhaled, for the body.

• The material composing the complete helmet is free of hazardous substances and does not present any risk for man or the environment.

• Regularly check the condition of the helmet and the filter:
  – Before each use, check correct positioning and fastening of the filter and the protective plates which must be exactly in the space described.
  – Keep the helmet far from flames.
  – The helmet must not be too close to the welding area.
  – In prolonged welding, every now and then check the helmet for any deformations or wear.
  – For particularly sensitive people, the materials that come in contact with the skin could cause allergic reactions.

• This automatic darkening helmet is only certified to protect the face and eyes from harmful ultraviolet and infra-red radiation, from sparks and welding sprays; it is not suitable for laser welding and oxy-acetylene welding and cutting or to protect the face from explosions or corrosive liquids.

• Only replace helmet parts with others specified in this manual. Non-compliance with this regulation can expose the operator to health risks.

• If the helmet does not darken or presents functionality problems, refer to the TROUBLESHOOTING chapter; if the problem persists, immediately stop using the helmet and contact your supervisor or distributor.

• Do not immerse the filter in water or other liquids; do not use solvents to clean the filter or the protective plates.

• Use the helmet only at temperatures: -5°C (+23°F) ÷ +55°C (+131°F).

• Store the helmet only at temperatures: -20°C (-4°F) ÷ +65°C (+149°F).

• Protect the filter and the protective plates from contact with liquids and dirt.

• Do not open the filter container.

• Never use the helmet without the internal or external transparent protective plates of the filter.

• Check compatibility of the protective plates of the filter and the helmet: both should be marked with the same impact resistance symbol against high speed particles, in this case F. If the marking symbols are not common to both, the protective plates of the filter and the helmet, then the lowest protection level of the helmet-filter assembly should be used.

• The eye protection against high speed particles worn over standard glasses can produce impact, thereby creating hazards for those who wear them.

• Do not use spare parts other than original TELWIN parts. Unauthorised modifications and replacement with non-original parts will void the warranty and expose the operator to the risk of personal injury.

• Remember to use the helmet, the automatic darkening filter and the relevant protective plates for a maximum of 2 years. The duration of these items depends on various factors such as the frequency of their use, cleaning, storage and maintenance. You are advised to frequently inspect and replace if damaged.

PRECAUTIONS
To protect the user’s safety and ensure the welding automatic darkening filter works properly, read these instructions carefully and consult a qualified instructor or supervisor before starting work.

• These filters and protection plates can be used in all welding processes, with the exception of oxy-acetylene welding and laser welding.
• The light protection plate in standard polycarbonate must be applied on both sides of the filters.
• Non-use of the protection plates can be hazardous for safety or cause irreparable damage to the automatic darkening filter.
• Use is planned of the helmet in the “GRIND” position (where present) exclusively for grinding.

2. INTRODUCTION AND GENERAL DESCRIPTION

The “TW POP” model helmet is composed of a central filter with automatic darkening TW106 and transparent external and internal front guards.
The helmet was designed to guarantee correct eye protection during welding, as well as providing the maximum performance both in facilitated assembly and the convenience and quality of use: it guarantees permanent protection against UV and IR radiation and sparks generated during the arc welding process.

4. DESCRIPTION

4.1 HELMET AND MAIN COMPONENTS ASSEMBLY (Fig. A)
4.2 HELMET ADJUSTMENTS (Fig. B)
4.2.1 Adjustment of the perimeter strap (Fig. B-1)
The helmet must be adjusted to efficiently protect the eyes and face during welding.
The position of the front and rear strap can be manually adjusted to perfectly adapt to head size.
Turn the knob (in some models, the knob must be pressed to turn it) to adapt the head strap.

4.2.2 Adjustment of the perimeter strip height (Fig. B-2)
The height can be adjusted to position the strap just over the eyebrows: tighten or loosen the two graduated belts placed on the upper part of the head.

4.2.3 Adjustment of the distance between the face and filter (Fig. B-3)
Loosen the external knobs and slide forward or back until you obtain the desired position, then tighten again.

4.2.4 Adjustment of inclination (Fig. B-4)
Ideal tilting of the helmet is where the eyes are perpendicular to the surface of the filter.
To adjust the visualisation angle, loosen the knobs on both sides of the helmet and set the desired tilting of the helmet. If it is not possible to obtain the desired tilting, press the side buttons and move the cursors simultaneously so that the helmet goes beyond limitation of the preset angle.

5. ASSEMBLY

Assemble as in the drawing (FIG. C).
Insert 1 battery type CR2450 in the filter before using the helmet (FIG. D).

6. USE

The helmet must always and only be used to protect the face and eyes during welding.
The helmet and therefore the zone of the visual filter glass must be kept, during welding, as near as possible to the eyes to protect them from luminous radiation and any drops of molten metal.

Before starting the welding process, check the filter, the external and internal guards are correctly positioned.

Position the “Grind” / “5-9” / “9-13” selector (FIG. D-4) in position “5-9” or “9-13”
Set the “Shade range” (FIG. D-1), to adjust the “Shade” luminous gradation scale according to the current and welding procedure.

Table 1 gives the recommended “Shade” luminous gradation numbers for using an electric arc welding machine to carry out common jobs and the different welding current intensity levels. Check the intensity of the current and the welding procedure are suitable for the luminous gradation of filter protection.

Adjust the “Sensitivity” (Fig. D-2) according to the luminous intensity of the welding arc.
Adjust the “delay-time” (FIG. D-3) to set the delay time for passage from the dark state to light state, after interrupting the arc and based on piece luminosity.
Before use, carry out an arc strike test or press the “Test” button (FIG. D-5), if present, to check darkening.

The helmet in the “GRIND” position (FIG. D-4) can only be used for grinding.
After use and however before repositioning it after work, the helmet must be checked to ensure it is intact and to eliminate any molten metal drops on the visual filter, which could reduce performance of the filter.

The helmet must always be repositioned in such a manner to avoid its permanent dimensional deformation or breaking the protective visual filter.

7. MAINTENANCE AND CLEANING

• Replace the battery when, pressing the “TEST” key, the “LOW BATTERY” led is on (FIG. D-5).
• Replace the transparent internal/external protection plates of the filter in the event of breakage, scratches, nicks and deformations. Cheap guards compromise good vision of what you are doing, dangerously lowering the level of protection of the helmet.
• Regularly clean the surface of the filter and the protection plates with a soft cloth with non-aggressive cleaning solutions, for example window cleaning formulas (do not pour the product directly on the filter).
• Regularly check the solar cells and sensors are not blocked or covered by dirt. If this is the case, clean them with a soft paper tissue, possibly lightly soaked with window cleaner (do not pour the product directly on the filter).
• Clean and disinfect the helmet only with water and soap or solvent-free products. Use of chemical products causes aesthetic defacing even up to a complete reduction in the intactness of the helmet.
• Good general care of the helmet allows to reduce its obsolescence to the minimum, both from the point of view of use and that of components on the helmet.
• Regularly clean the surface of the filter with a soft cloth with non-aggressive cleaning solutions, for example window cleaning formulas (do not pour the product directly on the filter).
• Regularly check the solar cells and sensors are not blocked or covered by dirt. If this is the case, clean them with a soft paper tissue, possibly lightly soaked with window cleaner (do not pour the product directly on the filter).

8. TROUBLESHOOTING

During helmet operation, common problems may arise, listed here with the relevant solutions:

• The filter does not darken or is unstable when switching from light to dark and vice versa.
  Possible solution:
  – The external transparent guard of the filter is dirty or damaged (change the external transparent guard).
  – The sensors are dirty (clean the sensor surface).
  – The level of welding current is too low (increase the sensitivity, if present, or replace the helmet with another one having a suitable filter for the purpose).

• Slow switching.
  Possible solution:
  – Operating temperature too low (do not use at ambient temperature under -5°C (+23°F).

• Poor visibility.
  Possible solution: – The external guard and/or the internal guard of the filter and/or the filter are dirty or damaged (clean the dirty components and replace damaged ones).
  – The surrounding ambient does not have sufficient light (provide more light to the surrounding ambient).
  – The scale gradation number is not correctly set (select the correct value in the models where possible).

ATTENTION!
If the aforementioned malfunctions cannot be resolved, immediately suspend use of the helmet and contact your nearest distributor.
