of adjustable-tint auto-darkening welding helmets can preset their helmets to darken to 10 when stick welding
at 60 Amps or preset it to darken to 12 when they weld at 250 Amps.
5. Adjust the Sensitivity - Turning the knob on the inner f lter "Sensitivity" from "low" to "high".
• Select minimum : Suitable for high amperage welding or welding in bright environmental light (e.g.
there is disturbing light from other welder's vicinity).
• Select maximum: Suitable for low amperage welding, using in pool light conditions (e.g. Pipe welding
where part of the arc 1s obscured from view) and where the welding arc becomes stable (e.g. TIG
welding).
• Select medium: Suitable for most types of welding indoors and outdoors.
6. Check the auto-darkening f lter: At the moment of starting welding, it automatically changes the f lter screen
