Sensitivity

The sensitivity of the photo detector system (which responds to the light from the welding arc) can be adjusted to accommodate a variety of welding methods and workplace conditions. In order to see the current sensitivity setting, momentarily press the Sensitivity button. To select another setting, press the Sensitivity button again while the LED is flashing, and continue to press until the LED shows the desired setting.

Position 1 Least sensitive setting. Used if there is interference from other welders’ arcs in the vicinity.

Position 2 Normal position. Used for most types of welding indoors and outdoors.

Position 3 Position for welding with low current or with stable welding arcs. (eg TIG welding)

Position 4 Extreme photo detector sensitivity. Suitable for very low current welding, use of inverter-type TIG welding machines or pipe welding where part of the arc is obscured from view.

Finding the right Sensitivity setting

In order to find a suitable sensitivity setting, start with the setting, before welding, in Position 2. This is the default position that functions in the majo- rity of situations. If the filter does not darken during welding as desired, raise the sensitivity to Position 3 or 4 until the welding filter switches reliably. Should the sensitivity be set too high, it is possible that the filter will remain in the dark state after welding is complete due to ambient light. In this case, adjust the sensitivity downward to a setting where the welding filter both dar- kens or lightens as desired.

Low battery indicator

The battery should be replaced when the low battery indicator flashes or shade and sensitivity LEDs do not flash when the buttons are pushed.

Note!

The welding filter may not go to dark position if the sensors are blocked or the welding arc is totally shielded.

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.
