PRECAUTIONS

Never place the helmet or the autodarkening welding filter on hot surface.

Scratched or damaged protection screens should be regularly replaced by original BALDER

ones. Before using the new protection screen, make sure to remove any additional protection

foil from both sides.

Use only BALDER BH3 within the temperature range of -10°C to +60°C.

Do not expose the autodarkening welding filter to liquids and protect it from dirt.

Use only original BALDER spare parts. In case of doubt, please contact your BALDER author-

ized dealer.

Failure to follow these instructions will invalidate the warranty. BALDER does not accept

responsibility for any problems which may arise from applications other than welding, or if

the instructions for use are not strictly followed. The BALDER BH3 welding helmet is manu-

factured to protect the welder’s face against spatters and hazardous ultraviolet and infrared

rays emitted during the welding process. It is not intended to be used as a protection against

impact, flying particles, molten metals, corrosive liquids or hazardous gases.

Materials which may come into contact with the wearer’s skin could cause allergic reactions to

susceptible individuals.

Welding helmet worn over standard ophthalmic spectacles may transmit impact, thus create a

hazard to the wearer.

If the helmet and the protection screen both do not carry the B marking, then only the S mark-

ing is valid.

BEFORE WELDING

Ensure that the helmet is correctly assembled and that it completely blocks any accidental

light. In the front, light may enter the helmet only through the viewing area of the autodarken-

ing welding filter.

Adjust the headgear to ensure maximum comfort and to provide the largest field of vision.

Select a suitable welding filter for the shield. Dimensions of the filter: 110x110 mm (see

BALDER leaflet).

Check the prescribed shade level for your welding application and adjust your autodarkening

filter accordingly (see the table with recommended shade levels).

STORAGE

When not in use the filter should be stored in a dry place within the temperature range of -20°C to

+65°C. Prolonged exposure to temperatures above 45°C may decrease the battery lifetime of the

autodarkening

welding filter. It is recommended to keep the solar cells of the

autodarkening

weld-

ing filter in the dark or not exposed to light during storage in order to maintain power down mode.

This can be achieved by simply placing the filter face down on the storage shelf.

MAINTENANCE AND CLEANING

It is always necessary to keep the solar cells and the light sensors of the autodarkening welding

filter free of dust and spatters: cleaning can be done with a soft tissue or a cloth soaked in mild

detergent (or alcohol). Never use aggressive solvents such as acetone. BALDER filters should

always be protected from both sides by protection screens (polycarbonate or CR39), which

should also be only cleaned with a soft tissue or cloth. If protection screens are in any way dam-

aged, they must be immediately replaced.

For your protection and maximum efficiency, please read this informa-

tion carefully before use.

filter, or during the replacement of the pro-

tection screens, make sure that all parts are

firmly in place thus preventing any light from

entering the helmet. Should there still be any

light entering, repeat the procedure until the

problem is eliminated, otherwise the helmet

must not be used for welding. Before placing

the new protection screens, always remove

the protection layers from both sides.

BH3 AIR HELMET ASSEMBLY

/ BH3 AIR - version of BH3 helmet with integrated air supply system for combi-

nation with Clean-air Power unit set /

If you have purchased the BH3 helmet in a combination with the integrated air supply

system, the helmet will be additionaly equiped with integrated airduct, hose connector

and air grill. Balder does not except responsibility for the results of a service performed

by anyone other than a Balder authorised service agent. Failure to follow this instruc-

tions may invalidate the warranty.

In order to assure adequate sealing in the hood

and meeting the safety standards, the BH3 AIR

must be additionally equiped with a pair of wash-

ers. The washers are attached into the two upper

inner pins of the external control frame.

Figure 1

Figure 2

WASHERS ASSEMBLY

The BH3 AIR helmet assembly is similar as described in the section BH3 HELMET AND HEAD-

GEAR ASSEMBLY. Besides some additional integrated parts, (airduct, hose connector and air

grill), which are to be assembled by the manufacturer only, the BH3 AIR helmet has also a hose

holder (X), face seal (Y) and a pair of washers (Z).

Hose holder (X) needs to be fixed onto the headgear (D) between the headgear (D) and the nut

(C), as shown on figure 1. The hose holder is designed in a way to allow use on either side of the

headgear, depending on the type of Clean-air power unit.

Face seal must be properly assembled with the BH3 AIR helmet. It’s position related to the helmet

and the headgear is evident from figure No.1, while exact position related to the BH3 AIR helmet,

airduct and hose holder is precisely described in the next section FACE SEAL REPLACEMENT.

2. 3.

FACE SEAL REPLACEMENT

MOUNTING OF THE HOSE

Both available versions of face seal (Standard and Flexi) have exactly the same plastic face

seal holder, so the replacing procedure is the same for both. In order to be able to observe

the details better, the assembly schemes will show the face seal holder without the face

seal (fabric part).

Remove the headgear in the oposite order as described in the section BH3 HELMET AND

HEADGEAR ASSEMBLY.

Pull the lower part of the face seal holder to release it from the airduct (1.).

Release the face seal holder from the two outside upper latches (2.).

Pull the face seal holder from the two inside upper latches (3.).

Take the new face seal and push the inner upper side of the face seal holder into the two up-

per inside latches (4.).

Push the outside upper part of the face seal holder into the two outside upper latches (5.).

Slide the lower part of the face seal holder into the gap between the helmet and airduct (6.).

Assemble the headgear as described in the section BH3 HELMET AND HEADGEAR AS-

SEMBLY.

Screw in the hose of PAPR (hose comes with

the Clean-air power unit set) as shown on the

scheme. Adjust the length of the hose between

the hose connector and the hose holder so you

achieve the maximum comfort. We recommend

this length to be 25-30 cm of non stretched hose,

so the upper loop would not be too long, as the

lenght should allow comfortable lifting of the

helmet. It is recommended that the length of the

hose from the hose connector to the Clean-air

power unit is adjusted, so that the hose follows

well the user’s back without being stretched.

Once the hose is placed into the hose holder,

adjust the height of the hose by simply pulling the

hose trough the hose holder upward or down-

wards. Fine adjustment of shape of the loop can

be achieved by turning the hose left or right.

AUTODARKENING WELDING PROTECTION FILTER

OPERATION

BALDER autodarkening welding protection filters operate on the basis of a liquid crystal light

shutter that protects the welder’s eyes against intense visible light emitted during the welding

process. In combination with the permanent passive IR/UV filter, it protects against hazardous

infrared (IR) and ultraviolet (UV) light. The protection against harmful radiation is present regard-

less of the shade level or potential malfunction of the filter, beyond the darkest shade number

marked on each specific model.

BALDER autodarkening welding protection filters are manufactured according to EN 379 require-

ments and are CE, DIN as well as DIN Plus certified. They are not intended to be used as a

protection against impacts, flying particles, molten metals, corrosive liquids or hazardous gases.

Replace potentional malfunctioned (check that the autodarkening filter turns dark if you strike the

welding arc) or physically damaged autodarkening welding filter.

Protection screens, both internal and external (polycarbonate or CR39), must be used in

conjunction with the autodarkening filter in order to protect it against permanent damage.

USAGE

An autodarkening welding protection filter built into a welding helmet is considered to be »Per-

sonal Protection Equipment« (PPE) protecting the eyes, face, ears and neck against direct and

indirect hazardous light of the welding arc. In case that you have only bought a filter without the

helmet, you need to select the appropriate helmet designed to be used in combination with an

autodarkening welding protection filter. It has to allow the filter, including the internal and external

protection screens, to be adequately mounted into the helmet. There should be no increased

point tensions caused by the fixing frame or mounting system, as they could cause severe dam-

age to the filter. Make sure that solar cells and photo-sensors are not covered by any part of the

helmet, as this could prevent the proper operation of the filter. If any of these conditions occur,

the filter may not be suitable for use.

FIELD OF APPLICATION

BALDER filters are suitable for all types of electro-welding: covered electrodes, MIG/MAG, TIG/

WIG, plasma welding, cutting and laser welding (only selected models with two shade ranges,

i.e.6-8 and 9-13), except for gas welding.

FUNCTIONS

BALDER filters are supplied ready for use. Check the degree of required protection for

specific welding procedure and if a certain model allows you, select the recommended

shade, light sensitivity as well as opening time delay.

Shade adjustment: Some models (Power DS, Power ES, Grand DS, Grand ES) enable shade

adjustment range from 9 to 13. Selected models Power GDS and Grand GDS have two shade

ranges, i.e. 6-8 and 9-13. It can be adjusted by the knob »Range« which is located on the filter.

The external knob for shade adjustment has two shade ranges (6-8 and 9-13) marked in two dif-

ferent typefaces (positive and negative). The adjustment of the knob »Range« defines the range

which is being used.

Adjustment of sensitivity: Most welding applications can be performed with welding light

sensitivity set to maximum. The maximum sensitivity level is appropriate for low welding current

work, TIG, or special applications. The welding light sensitivity has to be reduced only in some

specific surrounding lighting conditions in order to avoid unwanted triggering. As a simple rule

for optimum performance, it is recommended to set sensitivity to the maximum at the beginning

and then gradually reduce it, until the filter reacts only to the welding light flashes and without

annoying spurious triggering due to ambient light conditions (direct sun, intensive artificial light,

neighboring welder’s arcs etc.).
