Introduction

A welder‘s cap is a type of headgear used when performing certain types of welding to protect the eyes, 

face and neck from flash burn, ultraviolet light, sparks, infrared light, and heat The welder‘s cap consists 

of several parts (see spare parts list) An automatic welding filter combines a passive UV and a passive IR 

filter with an active filter, the luminous transmittance of which varies in the visible region of the spectrum, 

depending on the irradiance from the welding arc The luminous transmittance of the automatic welding 

filter has an initial high value (light state) After the welding arc strikes and within a defined switching time, 

the luminous transmittance of the filter changes to a low value (dark state)

Depending on the model, the welder‘s cap can be combined with a protective helmet or with bumpcap

First use

Initial assembly of the welder‘s cap is graphically described in the Quick Start Guide (pages 2- 3) In 

addition, you will find information on the functions and features of the  welder‘s cap in the Quick Start Guide

Safety guidelines

Read the Instruction Manual before using the welder‘s cap Check that the front cover lens is correctly 

assembled If it is not possible to eliminate errors, the  welder‘s cap should not be used

Expected Lifetime

The 

 welder‘s cap

 does not have an end-of-life date The product can be used as long as no visible or 

invisible damage or malfunctions occur

Precautions & restrictions on protection / Risks

During the welding process, heat and radiation are released, which can cause damage to the eyes and skin 

This product offers protection for the eyes and face When wearing the welder‘s cap, your eyes are always 

protected against ultraviolet and infrared radiation, regardless of the shade level To protect the rest of your 

body, appropriate protective clothing must also be worn In some circumstances, particles and substances 

released by the welding process can trigger allergic skin reactions in correspondingly predisposed 

persons Materials that come into contact with skin may cause allergic reactions to susceptible persons

The protective welder‘s cap  must only be used for welding and grinding and not for other applications 

The manufacturer assumes no liability when the welding helmet is used for purposes other than intended 

or with disregard for the operating instructions The welder‘s cap is suitable for all established welding 

procedures with low spatter according EN ISO 11611 Class 1 / A1 + A2 , 

excluding gas and laser welding

Please note the recommended protection level in accordance with EN169 (page 8). 

Scratched or damaged 

lenses must be replaced The welder‘s cap does not replace a safety helmet Depending on the model, 

the welder‘s cap can be combined with a protective helmet

The welder‘s cap can affect the field of view due to constructive specifications (no view on the side without 

turning the head)  and may affect a color perception due to the light transmission of the auto darkening 

filter As a result, signal lights or warning indicators may not be seen Further there is an impact hazard due 

to a larger contour (head with helmet on) The welder‘s cap also reduces the audio and heat perception

Guarantee & liability

Please see the instructions of the national sales organisation of the manufacturer for warranty provisions 

For further information in this respect, please contact your official dealer Warranty is only granted for 

material and manufacturing defects In the case of damage caused by improper use, unauthorised 

intervention or through usage not intended by the manufacturer, the warranty or liability are no longer 

valid Likewise, liability and the warranty are no longer valid if spare parts other than those sold by the 

manufacturer are used 

Use

1 

Protection level

 By turning the knob, you can set the protection level from between 9 to 12, according 

  to your choice

2 

Grind mode.

 By setting the shade level knob to GRIND, the shade cartridge is reset to the GRIND 

  mode The cartridge is deactivated in this mode and remains in the light state The shade level knob 

  should always be turned counterclockwise until the end of the GRIND position  

3 

Stand-by.

 When the welder‘s cap 

is NOT in use, the shade level should be set at GRIND 

           This increases battery life substantially! 

Washing

1 

ONLY 

the fabric head and neck guard of the welder‘s cap may be washed Under no circumstances 

should you wash the shade cartridge together with the plastic shield and electronics

2  Use a commercially available washing bag (The protruding hooks on the sewn-on synthetic part can 

damage other items of washing)

3  Let the welder‘s cap dry for at least one day after washing! 

  Explanation: the synthetic parts become saturated with water Their rigidity is thereby reduced and 

this leads to an imprecise fit on the mask One or two days are necessary before the synthetic material 

regains its previous rigidity 

4  Only wash according to the washing instruction (40 °C or 104 °F, do not dry clean, do not bleach, 

gentle drying cycle) 

5  After 15 washes, the flame-retardant properties of the textile are significantly reduced and must be 

replaced (available at your dealer)A discolored or perforated textile must be replaced

Batteries

The shade cartridge uses replaceable lithium button cell batteries of the CR2032 type The batteries have 

to be replaced when the LED on the box blinks red or the shade cartridge does not shade (see page 6) If 

the shade cartridge does not shade

1  Remove the battery cover carefully

2  Remove the batteries and dispose of these according to the national provisions for hazardous waste

3  Use the battery type CR2032 as shown in the picture

4  Carefully refit the battery cover

If the shade cartridge no longer darkens when the welding arc is fired, please check the polarity of the

 batteries If the shade cartridge does not function properly, even after the batteries have been replaced 

correctly, it has to be deemed no longer serviceable and replaced

Battery and battery life:

1  The battery lasts for approx 1,000 hours (active welding time) when welding at the medium shade 

level 

2  The battery lasts for approx 2 years (10,000h) if the welder‘s cap

is not used at all (GRIND mode) 

3  Battery life is substantially reduced if the welder‘s cap is stored where it is exposed to blazing sunlight 

(sensor against the sun) 

4  Only use new CR2032 batteries

Cleaning and disinfection

The shade cartridge and front cover lens can be cleaned regularly with a soft cloth in order to prolong their 

life No strong cleaning products, solvents, alcohol or cleaning products containing abrasives may be used 

Scratched or damaged visual panels should be replaced The textile may be used up to max 15 times to be 

washed, then it has to replaceA discolored or perforated textile must be replaced

Storage

The welder‘s cap should be stored at room temperature and low humidity In order to prolong the life of the 

batteries, store the welder‘s cap in its original packaging

Problem solving

The shade cartridge does not shade

→  Deactivate the Grind mode

→  Clean the sensors and front cover lens 

→  Check the light flow to the sensor

→  Replace the batteries 

The shade cartridge flickers

→  Replace the batteries 

Poor visibility

→  Clean or replace the front cover lens or inside cover lens

→  Adjust the shade level to suit the welding procedure

Turn up the ambient light

The welder‘s cap slips

→  Adjust the fabric part to the head size again
