JALUWELD Auto Darkening Welding Mask, Solar and Battery

The JALUWELD Welding Mask Auto Darkening is a polypropylene shell listed in the colour "Black-e93", with a 93 x 43 mm viewing window, a shade range the listing gives as DIN 4 in the light state and DIN 9-13 in the dark, a switching time of 1/25000s and a power system it describes as a CR2032 lithium battery plus a solar panel. It is number 7 in this guide at £29.99, with 4.5 stars from 1,647 ratings and 12th place in the Welding Helmets ranking Amazon shows on the listing itself.

Two sets of numbers on the same page do not agree. The bullet copy calls it "Light weight (1 LB)" — about 454 g — while the spec table gives the item weight, and the package weight, as 400 g, a gap of roughly 54 g. The product name says "Battery & Solar Powered"; the Power Source field says only Solar. The star breakdown shown adds up to 100 reviews (71 five-star, 15 four-star, 8 three-star, 3 two-star, 3 one-star) against a stated 1,647 ratings, and the listing also carries a field headed "Guaranteed software updates until", answered "unknown", on a welding helmet. Style is listed as MIG, although the copy says the variable DIN 9-13 shade suits various work. At £29.99 it sits at the cheaper end of this set and carries far more user feedback than the two most expensive helmets here, which between them hold 76 ratings. Every figure on this page comes from the Amazon listing as published — no weight, shade or battery number here was measured by us.
