Preparation and Operator Instructions

General
The welding helmets 3350 SERIES secure proper protection of the eyes during welding. They permanently secure protection against UV and IR radiation and sparks not only in clear but in dark condition as well.

• Shade degree of 3350 SERIES was matched in such a way to protect your eyes against injury by the welding arc.
• Direct looking at the welding arc is forbidden. Arc rays are very dangerous. They can cause painful conjunctivitis and irreparable changes in your pupil.
• Welding helmets 3350 SERIES allow you to observe the welding arc very precisely. You needn’t flip it up and down during welding. Both your hands are kept free and because of light weight, the helmet reduces your fatigue and you can gain evident time savings.

WARNING
Batteries not installed please insert before use.
When the arc is striking the filter automatically darkens.
Before welding

• Check the front cover lens and the front lens frame are securely in place.
• Select the shade level you need for your filter setting by the proper knob and the shade switch.
• Adjust headband so that the helmet is seated on the head as low as possible and near to your face. Adjust helmet angle when in the lowered position by turning headgear.
• Check the correct operation of the filter

Special Features

• Eyes are always protected against ultraviolet and infrared rays, regardless of the shade level.
• The switching time of the filter from dark to clear state can be adjusted manually. By the means of a delay time knob the opening time can be adjusted to fast or slow. Before welding adjust your delay time according to your welding process, in order to protect the eyes against esidual light of the afterglow of the work materials. The fastest opening time is set at 0.1 sec.

Important Note

• The helmets are only to be used to protect the eyes and face from radiation and sparks.
• Lincoln Electric does not accept any liability if the helmet is used for another purpose and improperly used. Helmets series Viking are not suitable for laser and gas-welding applications.
• Helmet must never be placed on hot surfaces.
• Never open or tamper with the shade filter.
• Protect the filter from liquid and dirty contact.
• Clean the filter surface regularly.
• Always keep sensors and solar cells clean
• Regularly replace the protective lens with Lincoln Electric originals.

WARNING

• Do not leave the workplace with the helmet lowered in position; a bright light surface could cause the filter darken unexpectedly.
• Helmets should never be used as sunglasses when driving as this could lead to incorrect identification of the color of traffic lights.
• Materials which may come into contact with the wearer’s skin could cause allergic reactions to susceptible individuals.
• Eye protectors against high speed particles worn over standard ophthalmic spectacles may transmit impacts, thus creating a hazard to the wearer .

Helmet Information
This Auto-Darkening Welding Helmet will automatically change from a light state (shade DIN3.5) to a dark state (shade DIN6-9 / 9-13) 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 8)

• Operating temperature: -10°C ~ 55°C (14°F ~ 131°F).
• Do not use or open the auto-darkening filter if damaged by shock, vibration 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 saturated.

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 four 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 immediately.
• Use only replacement parts specified in this manual.
• Do not use the helmet without inside and outside cover lenses properly installed.

Cartridge Operation/Features

Variable Shade Control
The shade can be adjusted from shade 5 to 8 and 9 to 13 based upon welding process or application (refer to shade selection chart on page 8). Shade is adjusted by setting the shade range switch to the proper range, then use the shade dual scale dial to set the desired shade. The shade range switch and dual scale dial are located on the ADF cartridge as shown below.
Test
Press and hold test to preview shade selection before welding. When released the viewing window will automatically return to the light state (3.5 Shade).
Sensitivity Knob
Adjust the light sensitivity by turning the SENSITIVITY knob to the left or right as shown in the figure below. Turning the knob all the way to the left, the HIGH setting, is typically selected for normal use. When helmet is used in the presence of excess ambient light or with another welding machine close by, improved helmet performance can be obtained with a lower setting by turning the knob to the right to reduce the sensitivity. Grind mode can be selected by rotating the sensitivity knob all the way to the right until an audible click is heard.
Grind mode is intended for grinding only not for welding.
Delay Knob
This control is designed to protect the welder’s eyes from the strong residual rays after welding.
Changing the DELAY knob will vary the dark to light time between 0.1 second (SHORT) to 1.0 second (LONG). LONG setting is recommended for high amperage applications where the weld puddle is still very bright after the welding arc has ceased and for situations where the filter may be temporarily blocked from seeing the welding arc.
Power
This ADF cartridge is powered by a replaceable battery and solar power.
WARNING
Batteries not installed please insert before use.
The battery is located at the bottom corner of the ADF cartridge. Replace battery when LOW BATTERY light is lit. See the specification chart on page 4 for type of battery required.
