Frequently Asked Questions - BY801E Vevor

How to replace the battery of the Vevor BY801E helmet?

The battery is located in the lower corner of the ADF cartridge. Unscrew the compartment and replace the two CR2032 batteries respecting polarity (+ side towards the inside of the helmet). Use the reset button to check proper operation.

How to adjust the shade of the auto-darkening filter?

Use the shade control button (No.1 on the diagram) to adjust the shade in Welding mode (No.9 to 13) or Cutting mode (No.5 to 9). Refer to the recommended shade table in the manual for each welding process.

What to do if the filter does not darken when the arc starts?

Check the sensitivity (SENSITIVITY knob): increase it if necessary. Clean or replace the front lens cover if dirty. Make sure the arc sensors are not obstructed by your arm or an obstacle. If the problem persists, the battery may be low.

How to clean the filter and cartridge?

Use a soft cloth and a soapy water solution to clean the ADF cartridge. For protective lenses, wipe gently or replace if scratched. Never use harsh solvents.

What welding modes are available on the BY801E?

Three modes: Welding (dark shade No.9-13), Cutting (No.5-9), and Grinding (fixed at No.4). Select the mode using the mode button on the helmet.

How to adjust the headband for better comfort?

Turn the knob at the back of the helmet to tighten or loosen. For tilt, use the adjustment lever on the right side. The front/back distance is adjusted by sliding the spring-loaded caps into one of four slots.

What is the lifespan of the CR2032 batteries?

The battery life depends on usage. The low battery indicator lights up 2 to 3 days before complete depletion. Replace the batteries as soon as possible to avoid malfunction.

Is the helmet suitable for low-amperage TIG welding?

Yes, the helmet is rated for TIG from 5 A in direct and alternating current. For very low amperages, set the sensitivity to maximum and ensure the sensors have a clear view of the arc.

How to replace the front protective lens?

Gently lift the outer lens cover using a flat tool in the groove, then remove it. Insert a new lens by pushing firmly until it clicks. Never use the helmet without the protective lens.

Arc Welding Hazards

Only qualified persons should install, operate, maintain, and repair the unit.

ARC RAYS can burn eyes and skin.

Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks from the weld.

• Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). Refer to Shade and sensitivity charts. Wear approved safety glasses with side shields under your helmet.
• Use protective screens or barriers to protect others from flash, glare, and sparks; warn others not to watch the arc.
• Wear body protection made from durable, flame-resistant material (leather, heavy cotton, wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
• Before welding, adjust the auto-darkening lens sensitivity setting to meet the application.
• Stop welding immediately if the auto-darkening lens does not darken when the arc is struck. See the Owner's Manual for more information.

WELDING HELMETS do not provide unlimited eye, ear, and face protection.

Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld.

• Use impact resistant safety spectacles or goggles and ear protection at all times when using this welding helmet.
• Do not use this helmet while working with or around explosives or corrosive liquids.
• Do not weld in the overhead position while using this helmet.
• Inspect the auto-lens frequently. Immediately replace any scratched, cracked, or pitted cover lenses or auto-lenses.

• NOISE can damage hearing.
• Noise from some processes or equipment can damage hearing.
• Wear approved ear protection if noise level is high.

READ INSTRUCTIONS.

Read and follow all labels and the Owner's Manual carefully before installing, operating, or servicing unit. Read the safety information at the beginning of the manual and in each section.

- Use only genuine replacement parts from the manufacturer.

- Perform maintenance and service according to the Owner's Manuals, industry standards, and national, state, and local codes.

FUMES AND GASES can be hazardous.

Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.

• Keep your head out of the fumes. Do not breathe the fumes.
• If inside, ventilate the area and/or use local forced ventilation at the arc to remove welding fumes and gases. The recommended way to determine adequate ventilation is to sample for the composition and quantity of fumes and gases to which personnel are exposed.
• If ventilation is poor, wear an approved air-supplied respirator.
• Read and understand the Safety Data Sheets (SDSs) and the manufacturer instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
• Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watch person nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is safe.
• Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form highly toxic irritating gases.
• Do not weld on coated metals, such as galvanized, lead, or cadmium plate steel, unless the coating is removed from the weld area, the area is well ventilated, and while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded.

Proposition 65 Warnings

Welding or cutting equipment produces fumes or gases which contain chemicals known to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code Section 25249.5

OPERATING INSTRUCTIONS

Reset Button And Low Battery Indicator

1. Reset Button: Press Reset button to check if the lens is working properly. When the Reset button is pressed, the lens should darken and return to the clear state. Do not use the helmet if the lens does not function as described.
2. Low Battery Indicator The low battery indicator lights when 2-3 days of battery life remain. If battery power is low, replace with CR2030 lithium batteries.

Lens Delay Control

1. Lens Delay Control

The lens delay control is used to adjust the time for the lens to switch to the clear state after welding.

The delay is particularly useful in eliminating bright after-rays present in higher amperage applications where the molten puddle remains bright momentarily after welding. Lens delay adjusts from min (0.10 second) to max (1.0 second).

Mode Control

Adjustments are possible.

1. Weld Mode

Used for most welding applications. In this mode the lens turns on when it optically senses a welding arc. Adjust shade, sensitivity, and delay settings as needed.

2. Cut Mode

Used for cutting applications. In this mode the lens turns on when it optically senses a cutter arc. Adjust shade, sensitivity, and delay settings as needed.

3. Grind Mode

Used for metal grinding applications. In this mode the lens is fixed at shade No. 4. No adjustments are possible.

Sensitivity Control

Press the "SENSITIVITY" button; it is selected according to the welding process and environmental light. The default sensitivity is medium.

1. Select minimum: Suitable for high amperage welding or welding in bright environmental light (for example, when there is disturbing light from another welder nearby).
2. Select maximum: Suitable for low amperage welding, use in poor light conditions (for example, pipe welding where part of the arc is obscured from view), and where the welding

arc becomes stable (for example, TIG welding).

Variable Shade Control

1 Variable Shade Control Use the control to adjust the lens shade in the darkened state. Use the table below to select the proper shade control setting based on your welding process. The shade ranges for each mode are as follows: Weld - No. 9 - No. 13; Cut - No. 5 - No. 9

- Start with a shade that is too dark to see the weld zone. Then, use a lighter shade that gives a sufficient view of the weld zone without going below the minimum.

ADJUSTING HEADGEAR

HEAD SIZE ADJUSTMENT: Headgear tightness is adjusted by turning the ratchet knob to the right or left to adjust for the desired head size. This knob is located at the back of the helmet.

ADJUSTMENT is made by adjusting the comfort, then placing the strap under the guide and snapping the pins into the holes to lock securely in place.

TILT: Tilt adjustment is located on the right side of the helmet. Loosen the headgear

tension knob and push the top end of the adjustment lever outward until the stop tab clears the notches. Then rotate the lever forward or back to the tilt position. The stop will automatically engage again when released, locking the helmet into position.

FORE / AFT ADJUSTMENT: Adjusts the distance between the user's face and the lens. To

adjust, slide and hold the spring-loaded caps upward while moving the head into one of four slotted locations. Once the desired distance has been achieved, release the cap and it will return to its resting position once the adapter is set in one of the four slots.

NOTE: Make sure both sides are equally positioned for proper orientation.

REPLACING THE BATTERY

This ADF is powered by a replaceable battery and solar power. The battery is located at the bottom corner of the ADF cartridge.

Replace the battery when the LOW BATTERY light is lit.
