Tæthedsgrad

Der kan indstilles til fem forskellige mørke tæthedsgrader 8, 9, 10, 11 og

12.Hvilken tæthedsgrad, der er indstillet ses ved at trykke på knappen Shade. For at vælge en ny tæthedsgrad trykkes på knappen Shade, og herefter, mens lysdioden blinker, trykkes igen på Shade-knappen, indtil lys- dioden blinker ved den ønskede tæthedsgrad.

Følsomhed

Følsomheden af fotocellerne, der reagerer på svejselyset , kan tilpasses forskellige svejseprocesser og arbejdsforhold. Tryk kort på knappen Sen- sitivity for at se, hvilken følsomhed, der er indstillet. Der kan vælges en anden indstilling ved at trykke på knappen igen og, mens lysdioden blinker, trykke flere gange indtil lysdioden blinker ved den ønskede stilling

Område 1 Den mindst følsomme indstilling. Benyttes ved forstyrren-

de lys fra andre, der svejser ved siden af.

Område 2 Normal indstilling. Bruges ved de fleste typer svejsning, indendørs som udendørs.

Område 3 Område til svejsning ved lave strømstyrker (Amp) og/eller, hvor der er en jævnt lysende lysbue (f.eks. TIG-svejsning ved lave svejsestrømme)

Område 4 Den højeste følsomhed af detektorerne. Bruges ved svejs- ninger med meget lave strømme, ved TIG-svejsning med inverterbaseret strømkilde, eller ved f.eks. rørsvejsninger, hvor lysbuen er delvist skjult for udsynet.

Sådan findes den rigtige indstilling af detektorernes følsomhed

Normalt indstilles inden svejsningen påbegyndes på område 2. Dette er den normale indstilling, der passer til de fleste svejseopgaver. Reagerer svej- sekassetten ikke I denne indstilling, når man begynder at svejse, indstilles på område 3 eller 4, hvorefter skift fra lys til mørk indstilling gerne skulle ske. Har man valgt for høj følsomhed, kan svejsekassetten forblive i mørk tilstand efter svejsningens ophør på grund af andet forstyrrende lys. Er det tilfældet, så juster følsomheden ned, indtil kassetten skifter mellem lys og mørk som ønsket.

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.
