Miller 287798 Welding Helmet

The Miller 287798 is an auto-darkening welding helmet designed for professional and hobbyist welders who need reliable eye protection across multiple processes. Its nylon shell and ratchet suspension provide a secure fit for extended work sessions.

Viewing Area 3.74 by 1.38 Inches

The 3.74 x 1.38 inch viewing window offers a clear field of vision for MIG, stick and TIG work rated down to 20 amps. Two arc sensors and a 1/3600 second switching speed deliver consistent darkening, while the fixed light state 3 and EN379 1/1/1/2 classification limit flexibility for very low-amperage or specialised tasks.

Solar Powered with Grind Mode

Solar power eliminates battery changes and the auto on/off function preserves energy between welds. A dedicated grind mode allows quick transitions without removing the helmet. The package includes two inside and five outside cover lenses, while ANSI and CSA certification confirms compliance with North American safety standards.

Questions about this item

Will the 3.74 in x 1.38 in viewing area on the 287798 helmet give me enough visibility when I am grinding between welds?

Yes, the helmet includes a Grind Mode that keeps the lens in its light state 3 so you can see clearly while grinding, then returns to auto-darkening when you strike an arc.

How can I confirm the auto-darkening filter is switching at the rated 1/3600 sec speed after I put the helmet on?

Strike an arc at or above the 20 A TIG rating; the two arc sensors will darken the lens to shade 379 classification 1/1/1/2 within the specified switching speed.

Which cover lenses are supplied with the 287798 and do I need to buy batteries separately?

The box contains two inside cover lenses and five outside cover lenses; power comes from the solar cell so no batteries are required.
