CORE SERIES WELDING HELMET
OPERATING MANUAL
1. Safety
Please read and understand all instructions before using.
• Be sure that the dark shade of the lens in the welding helmet is on the correct shade
number for your application.
• The helmet and lenses are not suitable for “overhead” welding application, laser welding,
or laser cutting applications.
• Welding helmets are designed to protect the eyes and face from sparks, spatter, and
harmful radiation under normal welding conditions.
• This helmet will not protect against explosive devices or corrosive liquids. Machine guards
or eye splash protection must be used when these hazards are present.
• Impact resistant, primary eye protection, spectacles or goggles that meet current ANSI
specifications, must be worn at all times when using this welding helmet.
• Avoid work positions that could expose unprotected areas of the body to sparks, spatter,
direct and/or reflected radiation. Use appropriate protection if exposure cannot be avoided.
• Before each use, check that the protection plates are clean and that no dirt is covering the
sensors on the front of the lens.
• Inspect all operating parts before each use for signs of wear or damage. Any scratched,
cracked, or pitted parts should be replaced immediately.
• Do not make any modifications to either the welding lens or helmet, other than those
specified in this manual. Do not use any replacement parts other than those specified in this
manual. Unauthorised modifications and replacement parts will void the warranty and expose
the user to the risk of personal injury.
• If this lens does not darken when striking arc, stop welding immediately and check the
helmet is in Weld Mode and not Grind Mode. If the issue persists, contact your local
UNIMIG Service Department.
• Do not immerse this lens in water.
• Do not use any solvents on any lens or helmet components.
• The recommended operating temperature range for this welding lens is -5°C to 55°C. Do
not use this device beyond these temperature limits.
• Failure to follow these warnings and/or failure to follow all of the operating instructions
could result in severe personal injury.
WARNING: Contains button battery, hazardous if swallowed. Keep out of reach
from children (whether the battery is new or used). Battery can cause severe or fatal
injuries in 2 hours or less if it is swallowed or placed inside any part of the body.
Medical attention should be sought immediately if it is suspected the battery has been
swallowed or placed inside any part of the body.

2. Features
98x48mm View Size
Get clear visibility in every situation. The 98x48mm viewing area lets you see every weld
with complete clarity.
External Grind Button
Seamlessly switch to grind mode with the click of a button. When the helmet is in grind
mode a small LED will illuminate, so you don’t need to take the helmet o to check.
9-13 Shade Control
Keep your eyes protected no matter the weld type. With a 9 to 13 shade range, you’ll be
covered while MIG, TIG or STICK welding, even when running as high as 500A.
4 Arc Sensors
Detect every arc instantly. The four optimally positioned arc sensors trigger the lens,
darkening it and keeping your eyes shielded from the start, even when you’re out of position.
Backup Battery
A CR2450 backup battery improves the performance and reliability of the auto-darkening filter.
4 Point Harness
Get the perfect fit and stay comfortable for hours. Adjust all 4 points of contact to suit you,
and have the weight spread more evenly, minimising neck strain.
EliteVision Lens Technology
See your weld clearly in true colour. EliteVision technology allows more colours from the
spectrum to pass through the view, giving you better optical clarity and reducing eye fatigue.

CORE SERIES WELDING HELMET
OPERATING MANUAL
Sensitivity Control
The responsiveness to dierent light levels in various welding processes can be adjusted in
the range from low to high.
Set the Sensitivity Dial (3) to your preferred level. Turn the dial counter-clockwise to
decrease sensitivity, and rotate it clockwise to increase sensitivity.
Low Sensitivity
• Suitable for high amperage welding and welding in bright light conditions (lamp light
or sunlight).
High Sensitivity
• Suitable for low amperage welding and use in poor light conditions.
• Suitable for use with steady arc process such as TIG welding.
• Under normal use, a higher sensitivity setting is recommended.
Delay Control
The length of time delay for the ADF to return to the light state after welding can be
adjusted in the range from fast to slow (0.1-0.9s). The time delay is for the protection of the
welder’s eyes from strong residual rays after welding.
Set the Delay Dial (4) to your preferred level. Turn the dial counter-clockwise to
decrease delay time, and rotate it clockwise to increase delay time.
Low Delay
• The time the ADF takes to lighten after welding becomes shorter. The shortest time is
about 0.1s depending on the welding point temperature and shade setting. This setting is
ideal for tack welding or production welding with short welds.
High Delay
• The time the ADF takes to lighten after welding becomes longer. The longest time is
about 0.8s depending on the welding point temperature and shade setting. This setting is
ideal for welding at high amperage where there is an afterglow from the weld.
Grind Mode
Press the Grind Mode Button (6) to initiate grind mode. Upon activation, the Grind Mode
Indicator (2) light will begin to blink. To deactivate grind mode and revert back to weld
mode, simply press the Grind Mode Button (6) again.
Note: Do not weld in the grind mode, the ADF will not darken.
Low Battery Indicator
When the backup battery is low, the Low Battery Indicator (1) will begin to blink. Replace
the battery when it is low, otherwise the ADF switching time will become slower, and shade
accuracy will be compromised.

Removing The ADF From The Helmet Shell
1. Switch both ADF frame locks to the
up position to unlock it from the helmet
shell.
2. Lift the bottom of the ADF up then slide
the unit down to remove it from the
helmet shell.
Power Supply & Replacing The Battery
The power of the auto-darkening helmet is provided by solar cells and a CR2450
lithium battery. To change the battery, remove the ADF from the ADF frame. The battery
compartment is on the top of the ADF, open the compartment to replace the battery.

Changing The Inner Lens Cover
Changing The Outer Lens Cover
Pry the inner lens cover up from the finger
groove at the top of the ADF. The inner lens
cover can then slide up and out of the ADF.
Replace with new inner lens cover.
With the ADF frame removed, simply lift out
the existing outer lens cover. Replace with
new outer lens cover.
