Main Characters

The safe structure design adopts a world famous style, conform to the ergonomic principle, and provides an ample internal space, which makes it easy to operate and comfortable to wear. The helmet shell materials with soft texture are resistant to high/low temperature, corrosion, flame-retardant and light-proof, with high strength, and durable. It may comprehensively protect your face, neck, ears and so on.
Liquid crystal of high quality and optical coating, and protection for shielding ultraviolet and infrared rays (level of protection: 16#) are adopted to protect welding operator from being injured by harmful rays such as ultraviolet rays, infrared rays, etc.
The original design of automatic transform technology used in controlling circuit make it possible for goggles to be able to reach 1/10000 second and change strong light to dark light. As a result, it can protect our eyes from being injured by sudden arc.
Unique design anti-interference switch avoids not seeing welding object clearly due to complex surrounding nearby
Dark shade DIN5~DlN9/DlN9~DlN13, stepless control, set by hand according to actual situation.
Dark to light: 0.1~0.8s, stepless control.
With cutting, grinding function.

Working Principle

Different with traditional passive shading lens, made from various additives and pigment. ADF adopts LCD as lens ADF, using the probe on mirror surface to probe the appearance and disappearance of arc when welding, and using electricity to drive shading level of the LCD to achieve the goal of protecting us from harmful rays, can absolutely reflect ultraviolet rays and infrared rays. In addition, hands are thoroughly set free. Welding is more exactly. Therefore, efficiency is improved.

Structure of the Product and Installation of Headband

Structure of the Product

Description of Headband Installation

Take out the headband, and disassemble it according to the exploded view below:
1. Sweat Band
2. Plastic Nut
3. Fix Set
4. Adjusting Rack
5. Angle Adjusting Shim
6. Position Sleeve
7. Locking Bolt
8. Head Band
9. Tightness Knob
Take out the mask and install the headband according to the exploded view below:

Description of Product Adjustment

Turn the headband first to make the headband adjusting knob at the back of the head, press with hand and turn counterclockwise the headband diameter adjusting knob to broaden the headband size; otherwise, narrow it,
Adjust the band depth location hole to adjust the lengthwise position of the headband from head top to eyes;
Loosen lug nuts at both sides to make the mask move back and forth in the long mobile hole of the head loop so as to adjust the distance from the window view to eyes;
Fix locating piece on different locating columns to adjust the window view angle, slightly adjust the required angle of elevation, horizontal view angle, and top view angle;
Loosen lug nuts at both sides to adjust the vertical angle of the mask, to turn up or down the mask; you may hear "chuck-chuck" during adjusting.

Auto Darkening Filter's Operation Instruction

Dark Shade

The table below is the darkness color number comparison table; please select correct darkness color number based on the actual working conditions so as to reach the optimal protection and work efficiency:

Sensitivity adjustment

Choose the appropriate sensitivity, not only realize the anti-interference capability, but also achieve better work.

When welding current is small, you need to put the "sensitivity" knob to high place, so you can detect weak stable arc;
When welding current is big, you need to put the "sensitivity" knob to low place, you can avoid the arc interference by others;
Sensitivity is stepless control, set by hand according to actual situation.

Delay time

Delay time is time from dark to light, Stepless control.

When welding current is big and the light of molten pool is very strong, you need to put the "delay" knob to high place, so you can avoid the glasses to be wounded by the light of molten pool.
If you want to do spot welding, you need to put the "delay" knob to low place, so you can improve the work efficiency
Adjust "delay" knob to middle place is suitable for most of welding mode.

Welding/Grinding function

The welding/grinding function is switched through the knob on the helmet body. When it is switched to "Grind", it means it enters grinding mode under which the auto darkening filter will not turn black when detecting any arc light; therefore, please switch to the correct position based on service conditions before using;

TEST button

If you put the "TEST' button, the filter turn black, the filter can work.

Low battery alarm

When the light of low battery is red, you need replace the new battery(CR2450), please replace the battery according to the view below:

Replacing the battery

Precautions for Use of Helmet

Before using the auto darkening welding helmet, please first tear off the films attached to the inside and outside PC screening glass of the window, adjusting the tightening knob between headband and helmet body, and then adjust the headband diameter and depth properly for wearing;
Test with standard incandescent lamps of 40W or above before using, the liquid crystal will turn black when you put lamps near it;
Do not put the helmet on any high-temperature weld joint after welding;
Do not take the helmet as safety helmet;
Replace unclear or damaged inside or outside screening glass timely to ensure the lines of sight;
In order to protect the product from damage, please do not clean it with clear water or cleaning solvent; please use soft tissues or cloth for cleaning;
In order to ensure proper working of the auto darkening filter, please keep the sensors of weld arc on it clean and out other objects;
When the ambient temperature is relatively low, the liquid crystal materials in the cartridge may become a little retardant while it has no influence on various protective properties.
