VEVOR METIS BY801E Auto-Darkening Welding Helmet: features and specs

The VEVOR METIS BY801E is an auto-darkening welding helmet with a true colour lens, four arc sensors and a solar-assisted power system. It is meant for TIG, MIG and arc welding, as well as cutting and grinding. Here is what the specs mean and what to confirm before relying on it.

How an auto-darkening helmet works

A fixed-shade helmet has to be flipped down before striking an arc. An auto-darkening helmet has a lens that stays light until sensors detect the arc, then darkens within a fraction of a second. That lets a welder keep the helmet down while lining up a joint. VEVOR says the lens darkens in 1/20000 of a second, and uses four arc sensors to pick up the light from different angles.

True colour viewing

The viewing area measures 3.94 x 3.15 inches (100 x 80 mm). VEVOR describes it as true colour technology with 1/1/1/1 optical clarity, which refers to a classification covering optical class, light diffusion, variations in luminous transmittance and angle dependence. 1/1/1/1 is the highest class in that scheme. True colour lenses aim to show the workpiece in more natural tones than the green tint of older lenses, which can help when judging the weld pool.

Shade range and working modes

VEVOR lists three modes with adjustable DIN shade levels:

• Grind mode: DIN 4.
• Cut mode: DIN 5 to 9.
• Weld mode: DIN 9 to 13.

A higher DIN number is darker. The right shade depends on the process and the amperage, so check a welding shade chart or your welding equipment's manual rather than guessing.

Power

The helmet has solar charging and two lithium batteries, so it doesn't rely on frequent battery swaps. VEVOR says this gives a stable supply. As with any solar-assisted helmet, it's worth checking that the lens reacts properly before each session.

Fit and comfort

An adjustable top strap, plus width and angle adjustment knobs, lets the wearer set the fit. VEVOR says the shell is made from heat- and impact-resistant materials and blocks flying sparks. The helmet weighs about 1.5 lb and measures roughly 14.2 x 9.4 x 8.3 inches.

Safety standards

Welding involves intense light, heat, sparks and fumes. Look for a marking showing the helmet meets the standard that applies where you work, such as ANSI Z87.1 or CSA Z94.3 in North America, and follow the manual. The listing doesn't state which certifications this model carries, so confirm that with VEVOR before buying. Wear appropriate gloves, clothing and ventilation as well.

Who it suits

It suits hobbyists and workshop welders who switch between welding, cutting and grinding and want one helmet with separate modes.

What to check before you buy

• Certification: confirm the standards that apply to your workplace or region.
• Process: check that the shade range suits your welding type and amperage.
• Fit over glasses or a respirator: consider whether you wear either under the hood.
• Spare parts: ask about replacement lenses, cover plates and batteries.
• Sensitivity and delay settings: read the manual for how to adjust them.

The short version

• An auto-darkening helmet with a 3.94 x 3.15 inch true colour lens.
• Four arc sensors and a stated 1/20000 second darkening time.
• DIN 4 grind, DIN 5-9 cut and DIN 9-13 weld modes.
• Solar charging with two lithium batteries.
• Check the certifications and shade chart for your work.
