keevitusmeetoditele ja töökoha olukorrale. Selleks, et teada saada, milline valgustundlikkusrežiim on valitud, vajutage korraks Sensitivity nuppu. Val- gustundlikkuse muutmiseks vajutage dioodi vilkumise ajal niikaua Sensiti- vity nuppu, kuni olete jõudnud soovitava režiimini.

Asend 1 Väikseim tundlikkus. Kasutatakse, kui maski tööd häirib lähe- duses keevitamisest tekkiv valgus.

Asend 2 Tavaasend. Kasutatakse enamuse keevitusliikide puhul nii ruu- mides kui ka välitingimustes (nt. päikese käes) keevitamisel.

Asend 3 Seda asendit kasutatakse keevitamisel nõrga vooluga või sta- biilse keevituskaarega (nt. TIG keevitus).

Asend 4 Fotoandurite ülitundlikkus. Sobib väga nõrga vooluga keevita- miseks, invert-tüüpi TIG keevitusel või toru keevitamisel, kui osa kaarleegist pole vaateväljas.

Õige valgustundlikkuse leidmine

Filtri õige tundlikkuse leidmiseks seadke enne keevitama asumist tundlik- kus asendisse 2. See on normaalasend, mis sobib praktiliselt kõikidele kee- vitusliikidele. Kui keevitusfilter ei tumene keevituse vältel nagu soovitud, tõstke tundlikkust asendini 3 või 4, kuni toimub keevitusfiltri kindel tumene- mine. Juhul, kui on valitud liiga tundlik asend, võib juhtuda, et filter jääb peale keevitamise lõpetamist ümbritseva valguse tõttu tumedaks. Sel juhul valige väiksem tundlikkus, nii et filter tumeneb ja läheb heledaks nii nagu on soovitud.

Patarei tühjenemise indikaator

Patarei tuleb välja vahetada siis, kui patarei tühjenemise indikaator hakkab vilkuma või kui tumeduse ja tundlikkuse dioodid ei hakka nuppudele vaju- tades vilkuma.

Märkus!

Keevitusfilter võib mitte tumeneda, kui fotosensorid on kaetud või kui kee- vituskaar on täielikult kaetud.

Märkus!

Vilkuvad valgusallikad (nt turvavilkurid) võivad mõjutada keevitusfiltrit ja panna filtri vilkuma, kui keevitamist ei toimu. Selline mõju võib olla isegi kau- gel asuval valgusallikal ja ka peegeldunud valgusel. Keevituspiirkond peab olema kaitstud selliste kõrvaliste valgusallikate eest.

SL specifications

3M SL, also known as 3M Science of Safety, is an innovative product line that blends advanced materials science with cutting-edge technologies to enhance personal safety and workplace productivity. Designed for various industries, including healthcare, construction, and manufacturing, 3M SL focuses on delivering solutions that prioritize user protection without compromising comfort.

One of the standout features of 3M SL products is their exceptional breathability. Utilizing state-of-the-art filtration technology, 3M SL mask designs allow for optimal airflow while effectively filtering out harmful particles. This is particularly crucial in high-risk environments where prolonged usage is required. The specialized materials used in these masks contribute to a lightweight feel, ensuring that users can wear them for extended periods without discomfort.

Another significant characteristic of 3M SL is its commitment to standard compliance. The products are rigorously tested to meet or exceed rigorous safety standards, such as NIOSH and EN regulations. This compliance not only assures users of their effectiveness in protecting against airborne contaminants but also emphasizes 3M's dedication to maintaining the highest quality assurance levels.

In addition to these features, 3M SL employs innovative technologies, such as the use of advanced electrostatic filters. These filters generate a charged static field that attracts and captures smaller particles more efficiently than traditional filtering methods. This technology enhances protection while reducing breathing resistance, further contributing to user comfort.

3M SL also emphasizes versatility in its product offerings. From surgical masks designed for healthcare professionals to respirators suitable for industrial applications, the range caters to a diverse audience. This adaptability ensures that varying levels of protection and comfort are available to meet the specific needs of different users.

Ergonomic designs play a crucial role in the 3M SL range. With features such as adjustable nose clips and soft inner materials, the products are tailored to fit a variety of face shapes, enhancing both comfort and efficacy. This thoughtful design approach minimizes gaps that could allow unfiltered air to enter, maximizing protection.

Lastly, 3M SL embraces sustainability through responsible material sourcing and manufacturing processes, making it a forward-thinking option in personal protection. By investing in sustainable practices, 3M is not only committed to user safety but also to environmental stewardship.

In conclusion, 3M SL stands out in the crowded market of personal protective equipment by leveraging advanced materials science, innovative technologies, and ergonomic design to deliver superior comfort and safety. The combination of breathability, compliance with safety standards, and versatile applications makes 3M SL a leading choice for anyone seeking reliable protection in challenging environments.
