Lincoln Electric IM10150 VIKING 1740 SERIES AUTO-DARKENING HELMETS - Manual (Page 4)

HELMET INFORMATION
This Auto-Darkening Welding Helmet will automatically change from a light
state (shade DIN4) to a dark state (shade DIN9-13) when arc welding starts.
The filter automatically returns to a light state when the arc stops.
Match your welding application to the shade indicated on the shade chart.
(See Page 6)
• Operating temperature: 14°F ~ 131°F (-10°C ~ 55°C).
• Do not use or open the auto-darkening filter if damaged by shock, vibra-
tion or pressure.
• Keep the sensors and solar cell clean. Clean the filter cartridge using a
soapy water solution and soft cloth which should be damp but not saturat-
ed.
This Auto-Darkening Welding Helmet is designed for use with GMAW, GTAW,
MMAW welding, or Plasma Arc and air carbon arc cutting.
The cartridge provides protection from harmful UV and IR radiation, in both
dark and light states.
The cartridge contains two sensors to detect the light from the welding arc,
resulting in the lens darkening to a selected welding shade.
• Do not use solvents or abrasive cleaning detergent.
• If cover lens is spattered or covered with dirt, it should be replaced imme-
diately.
• Use only replacement parts specified in this manual.
• Do not use the helmet without inside and outside cover lenses properly
installed.

SAFETY WARNINGS – READ BEFORE USING
ARC Rays can injure eyes and burn skin
• Before welding, always inspect helmet and filter lens to be sure they are fitted
properly, in good condition and not damaged.
• Check to see that the clear lens is clean and securely attached to the helmet.
• Always wear safety glasses or goggles under the welding helmet and protective
clothing to protect your skin from radiation, burns and spatter.
• Ensure that optical radiation from other welderʼs arcs in the immediate area
does not enter in from behind the helmet and auto-darkening filter.
Note: Auto-darkening filters in Lincoln helmets are designed to protect the user against harmful
ultra-violet and infrared rays both in the dark and light states. No matter what shade the filter is
set to, the UV/IR protection is always present.
FUMES AND GASES can be dangerous to your health.
• Keep your head out of fumes.
• Use enough ventilation or exhaust at the arc or both to keep fumes and gases
from your breathing zone and general area.
• When welding with electrodes which require special ventilation such as
stainless or hard facing (see instructions on container or MSDS) or on
lead or cadmium plated steel and other metals or coatings which pro-
duce highly toxic fumes, keep exposure as low as possible and within
applicable OSHA PEL and ACGIH TLV limits using local exhaust or
mechanical ventilation. In confined spaces or in some circumstances,
outdoors, a respirator may be required. Additional precautions are also
required when welding on galvanized steel.
