REPLACE THE FILTER IF EVIDENT SIGNS OF DAMAGE SUCH AS CUTS OR WELDING MATERIAL DEPOSITS APPEAR PERMANENTLY
ON ITS SURFACE AND, IN ANY CASE, AFTER SIX MONTHS. THE FILTER, ANY COVERINGS AND THE INNER AND OUTER PROTECTION
SHIELDS MUST ALSO BE REPLACED AFTER EACH SERIOUS IMPACT.
The filter is characterised by a marking with the following meaning:
FILTER MARKINGS
Dark shade number
Identification code
Optical class
Marking
Optic class 3 filters and shields are not suitable for prolonged use.
The material that comes into contact with the skin can cause allergy reactions in people with particularly sensitive skin.
The certification procedure for the XTW filter required by Art. 10 of the 89/686/EEC Directive was carried out by DIN CERTO GmbH PrÜf-und
Zertifizierungszentrum Aalen Augenschutz und persÖnliche SchutzausrÜstung Gartenstraße 133, 73430 Aalen, being a notified body of the
European Commission (identification code 0196).
Table 1 gives the dark shade levels that are recommended for common electric arc welding procedures at different welding current intensity
levels.
ASSEMBLING THE MASK AND THE FILTER
Assemble as shown in the figure (Fig. A).
Attention, do not tighten too much, otherwise the threads will ruin, and the mask characteristics and the filter glass seal will not be suitably fixed.
The operator who carries out replacement operations must have clean hands or wear non-abrasive gloves.
INFORMATION ON THE MARKING
The marking in the inner lower front section of the TWFR mask is made up of a series of symbols with the following meaning:
Identification code
Standard number that was referred to for requesting certification
CE marking
Mechanical strength, low energy impact
The certification procedure for the TWFR mask indicated in Art. 10 of the 89/686/EEC Directive was carried out by DIN CERTO Gesellschaft für
