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. 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.

Features

92x41mm View Size

Get clear visibility in every situation. The 92x41mm viewing area lets you see every weld with complete clarity.

External Grind

Seamlessly switch to grind mode with the twist of a knob. No need to take the helmet off and on.

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.

2 Arc Sensors

Detect every arc instantly. The two optimally positioned arc sensors trigger the lens, darkening it and keeping your eyes shielded from the start.

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.

Operating Instructions

Sensitivity Dial (Low to High)
Delay Dial (Short to Long)
Shade/Grind Selector Knob

Manual Shade Control

Choose your preferred shade by twisting the Shade Selector Knob (5) to the matching shade number (9-13).

Note:

Choose an optimum shade number for the required welding process or application.
If this lens does not darken when striking an 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.

Sensitivity Control

The responsiveness to different light levels in various welding processes can be adjusted in the range from low to high.
Set the Sensitivity Dial (1) to your preferred level. Turn the dial counter-clockwise arrow-rotate-left to decrease sensitivity, and rotate it clockwise arrow-rotate-right 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 (0.1-0.8s). The time delay is for the protection of the welder’s eyes from strong residual rays after welding.
Set the Delay Dial (2) to your preferred level. Turn the dial counter- clockwise arrow-rotate-left to decrease delay time, and rotate it clockwise arrow-rotate-right to increase delay time.

Short 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.

Long 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

Turn the Shade/Grind Selector Knob(3) to “GRIND” to initiate grind mode.

Note: Do not weld in the grind mode, the ADF will not darken.

Removing The ADF And Changing The Lens Cover

Removing The ADF From The Helmet Shell

UNIMIG-U21033-Origin-Series-Welding-Helmet-fig-5

Switch both ADF frame locks to the up position to unlock it from the helmet shell.
Lift the bottom of the ADF up then slide the unit down to remove it from the helmet shell.

Changing The Inner 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.

Changing The Outer Lens Cover

With the ADF frame removed, simply lift out the existing outer lens cover. Replace with new outer lens cover.

Installing A Magnification Lens

Slide the magnification lens down through the magnification lens holder.

Additional Instructions

Be sure that the helmet is used in the correct condition and according to the safety requirements.
There is a liquid crystal-valve in the filter, although it has inner and outer protection covers, it is important to avoid heavy knocks to the helmet.
The outer protective shell of the helmet should be periodically inspected and cleaned. In the case of a break, crack, pitting or other damage, the helmet shell must be replaced.
To operate more efficiently and safely, please select the correct dark shade number.
The arc light must be visible completely by all arc sensors. If not, the ADF may struggle to detect an arc and may not activate the selected shade.
Please use the automatic filter at a temperature between -5°C – 65°C.
Do not disassemble the filter. If any problems arise, please contact your local UNIMIG service department.

Troubleshooting

The ADF does not darken when welding

Stop welding or cutting immediately.
Make sure the sensors are facing the arc and there are no obstructions.
Check the mode is on WELD, not GRIND.
Review sensitivity recommendations and adjust sensitivity if possible.
Replace the battery if necessary.

The ADF stays dark after welding or there is no arc present

Adjust the sensitivity to a lower level.
If the worksite is too bright, it is recommended to reduce the surrounding light level.

The ADF switches during welding

Increase the sensitivity if possible.
Make sure the sensors are facing the arc and there are no obstructions.
Increasing Delay 0.1−0.3 seconds may also reduce switching.

Warranty

UNIMIG Origin Series auto-darkening welding helmets are covered for warranty for up to two years from the date of purchase from authorised UNIMIG dealers. The duration of use depends on various factors such as use, cleaning storage and maintenance. Frequent inspections are recommended.
