ffiig gu urre e B B::1 1– –B B::3 3)).
The Speedglas SL welding shield is designed to be used in arc welding
applications where shade 8-12 is recommended.
Shade number should be chosen according to table on page 185.
The unit is suitable for all arc welding processes such as MMA, MIG, MAG,
TIG and Plasma Arc.
The Speedglas SL welding shield gives permanent protection (shade 12)
against harmful UV- and IR-radiation, regardless of whether the filter is in
the light or dark state or whether the autodarkening function is operational.
The welding filter has two photo sensors that react independently and cause
the filter to darken when a welding arc is struck.
Two lithium batteries are used as the power source. (3V CR2032)
The Speedglas SL welding shield is equipped with an auto on function and
will automatically switch off when not used.
Note!
Use only with original Speedglas brand spare parts such as inner and outer
protection plates according to the part numbers provided in these instruc-
tions. The use of substitute components might impair protection and may
invalidate claims under the warranty or cause the shield to be non compli-
ant with Protection Classifications and approvals.
Note!
The Speedglas SL welding shield is not suitable for laser welding, laser cut-
ting or gas welding/cutting (e.g. oxyacetylene). The Speedglas SL welding
shield is designed for all uses except heavy duty overhead welding/cutting
operation due to the risk of burns from falling molten metal.
Markings
The welding filter is marked with the shade range.
The eye and face protection classification is made according to EN 379, EN
166, EN 169 and EN 175.
