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. Refer to for additional safety information. 1 HELMET INFORMATION This Auto-Darkening Welding Helmet will automatically change from a light state (shade 3.5) to a dark state (Shade 9-13) when arc welding starts. The filter automatically returns to a light state when the arc stops. Shade control adjustments can be made while welding. 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. 2 SPECIFICATIONS LCD Viewing Area 97 x 44mm (3.82 x 1.73in) Cartridge size 110 x 90mm (4.33 x 3.54in) UV/IR Protection Up to Shade DIN 16 at all times Arc Sensors 2 Light State Shade DIN 4 Variable Welding Shades DIN 9 to 13 Shade Control External knob -full adjustment Power Supply Solar cells -no battery required Power On/Off Fully automatic Light to Dark Switching Time 0.00004 sec (1/25,000 sec) Sensitivity Control High (normal) and Low (extreme ambient light) Delay Control (Dark to Light) (0.25~0.35s
