Frequently Asked Questions - BY433E Vevor

How to adjust the shade on the Vevor BY433E helmet?

Use the shade control knob on the helmet. Turn it to select the desired shade within the range #9 to #13 in dark mode. Refer to the recommended shade chart in the manual based on the welding process and current intensity.

What to do if the lens does not darken when the arc is struck?

First check the sensitivity setting: increase it if necessary. Make sure the arc sensors are not blocked by your arm or another obstacle. Also clean the front protective lens. If the problem persists, test the lens with the test button. If it still does not darken, replace the battery (CR2032) or contact the dealer.

How to replace the welding helmet battery?

The battery is located in the lower corner of the ADF cartridge. When the 'LOW BATTERY' indicator lights up, remove the cartridge from the ADF holder and open the battery compartment. Replace the two CR2032 lithium batteries respecting polarity (+ toward the inside of the helmet). Close and reinstall the cartridge.

How to clean the lens and helmet?

Use a mild soapy water solution and a non-abrasive cloth to clean the front protective lens and the ADF cartridge. Avoid solvents. Immediately replace any scratched, cracked, or pitted lens. For the helmet, wipe it with a damp cloth.

What safety standards does this helmet meet?

This helmet complies with ANSI Z49.1 and ANSI Z87.1 standards for eye and face protection during welding. It offers full UV/IR protection. Do not use it near explosives or corrosive liquids.

Is this helmet suitable for TIG welding?

Yes, it is suitable for TIG welding with DC current of at least 15 A and AC current of at least 15 A. Set sensitivity to maximum for low amperages and use the recommended shade (#8 to #10 depending on current).

How to adjust the helmet size and tilt?

For size, turn the ratchet knob at the back of the headband. For tilt, loosen the right headband, press the tension button, and rotate the tilt lever to the desired position. The front/rear adjustment is done by sliding the spring caps in the slots.

Why does the lens remain dark after welding?

This may be due to a sensitivity setting that is too high or a return delay that is too long. Reduce the sensitivity and adjust the delay between 0.1 and 1.0 second using the delay control knob. If the problem persists, check the battery status.

How to replace the front protective lens?

Lift the front lens lever from the groove and remove the outer cover. Replace it with a new protective lens (part number BY-010003). Make sure it is properly snapped in. Never use the auto-darkening lens without protection.

What are the main safety warnings?

Never look at the arc without proper protection. Always wear safety glasses under the helmet. Use protective screens for others. Do not weld in a confined space without ventilation. Follow California Proposition 65 guidelines. Stop immediately if the lens does not darken.

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
