MODE SELECTION
1) Welding/grinding selection switch: when
grinding, the helmet cannot provide adequate protection if
the particles coming out from the metal surface are heavier
than 43 grams and if their speed exceeds 120 m/s. The
welding helmet is in conformity with the DIN EN
175:1997 standard (impact resistance level B). This
helmet cannot provide the protection for other body parts
so that users should wear appropriate protective
equipment.
2) Sensitivity adjustment knob: Before welding, set
the sensitivity at the highest level, and if the interference
with the ambient light is taken into account (the filter
darkens even before welding is started), it is necessary to
set the sensitivity at lower values, until the filter returns to a
clearer state (do not expose the helmet to the source of
light in the room during welding, but turn it only towards
the work piece). During welding, the sensitivity adjustment
knob should be set at the highest level, otherwise the filter
will not have a quick shading response.
Warning: The operator must immediately stop using this
helmet if the filter does not darken, if darkening speed is
low or if the filter flickers. In this case, you should contact
your supplier.
3) Shade Number Selection Knob - before welding is
started, set the shade number selection knob at the correct
value, depending on the type of welding process and
welding current, in order to carry out the test welding (See
Table No. 1 for Shade Number Selection). If the filter's
shade is too dark or too clear, gently set the shade knob so
that you can see a weld and though it does not glow you
can still notice the melted zone. Please consider the fact
that using the helmet with the incorrectly set shade number
(too dark or too clear) may cause severe damages to the
eyes over long time period.
WARNING: In the case that the filter does not darken, or the
shade number is insufficient, or darkening is too slow or the
filter flickers, please find out the causes. If the operator
