3. Operation & Safety
WARNING: IF YOU ENCOUNTER ANY PROBLEMS WITH THE HELMET BEFORE OR DURING USE IT IS IMPORTANT THAT YOU DO NOT CONTINUE WITH THE WELDING
PROCESS. IF THE FILTER FAILS TO DARKEN CORRECTLY, FLASHES OR IS UNABLE TO ATTAIN THE APPROPRIATE SHADE TO PROTECT YOUR EYES YOU SHOULD STOP
IMMEDIATELY AND CONTACT YOUR JEFFERSON DEALER OR SUPPLIER.
3.3 DIN Shade Delay Setting
It is important that the correct delay setting is used for your welding process to avoid
any sudden aring when you nish the welding process and the welding arc is broken.
When the welding arc is broken it is possible for residual arc to are from the molten
welding pool which can be hazardous if the helmet has already automatically adjusted
the DIN shade to a lighter setting. To accommodate for this, the helmet is equipped with
a Delay Time Switch for additional eye protection which can be set to three positions -
depending on the welding process:
1) Long = 0.6 to 0.9 second delay
2) Middle = 0.4 to 0.6 second delay
3) Short = 0.3 to 0.5 second delay
It is important that you use the correct delay & sensitivity setting to suit your
welding process and that you test the battery and filter before use.

3.1 Welding Protection
●Ensure that the helmet is not used in conditions were welding spatter is more than
43g and exceeding 120m/s.
●The helmet is manufactured to DIN BS EN175:1997 (Impact Level B) please ensure
that the appropriate protective clothing is worn to protect any other parts of the body
exposed during the welding process.
3.2 Sensitivity, Mode and DIN Shade Settings
●Before you start welding adjust the Mode, Sensitivity and DIN Shade to the
appropriate settings for the welding process (see Fig1a & Fig1b) and arc amperage
(see table on page 2).
●Continue to adjust the DIN shade settings to attain the appropriate brightness to allow
you to see the welding molten pool and the welding spot without glare.
3.4 Testing
1. Testing the Battery:
You can test the lithium battery is charged by checking that the Bat-
tery Indicator Light is on. The Battery Indicator Light is located
beside the Test button on the control panel (see Fig 2). If the red light
is not displaying or if the light is weak you need to replace the
batteries. The helmet takes two CR2450 type batteries.
2. Testing the Filter:
You can test the lter by pressing the Test button on the control panel
(see Fig 2).
If the battery indicator is on and the lter shade is not darkening when
you press the Test button there is a fault with the lter and it should
not be used to prevent the risk of injury.

3.6 Adjusting the Headgear
●It is important that the Helmet ts the user comfortably and securely before
welding begins.
●The helmet can be adjusted in 4 places to allow you to establish the best t
(see Fig 4).

3.5 The Magnifying Lens
A magnifying lens is available for this model (sold separately).
The lens is xed over the visor shown in Fig 3.
1. Top Headband - Adust the depth of the headband to fit accordingly
2. Filter Harness - Adjust to set the correct distance between the welders eyes and the lter lens
3. Back Headband - Loosen or tighten to attain a comfortable and secure t
4. Incline Angle - Adjust to set the incline angle of the helmet relative to the welders face and the position of the welders eyes relative to the lter
lens
Note: This helmet headband is designed with a mechanism that helps to adjust the centre of gravity on the helmet when the visor is up and down.
This mechanism helps to reduce the weight on the neck and reduce fatigue - making the helmet more comfortable and secure when you are
working.
