How to Get Your Harbor Freight Welding Helmet Working Again

Published 2023-05-01
In this video I replace the internal batteries on the Harbor Freight / Chicago Electric auto darkening welding helmet. It's an easy job. Instead of resoldering the internal batteries, I am adding an external battery holder to make replacing the batteries a breeze next time.

The other video I did:

Battery Holder:

Batteries: (Originals were a different part number, but the CR2032 battery will work fine.)

    This worked like a charm. Thanks

    Could also use a 4aaa battery cradle to get longer battery life.

    This is a GREAT hack!!!! Awesome job with updating from your previous video. You should probably pin a comment with a hyperlink to this video mentioning the update and also recommend it using one of those tiles at the end of the video. I never even knew there were cases like the one you used! If there's enough space I might clean a portion on the inside with isopropyl alcohol and gorilla tape him in rather than drilling the helmet. Either way this was an EXCELLENT recommend 👍👍👍

    Great video thanks . I was using mine today and all the sudden I got flashed , it stopped darkening all the sudden

    Could have just jumped the left side + - leads and just ran the positive and negative on the right side. Less wire to run across the top of the circuit board.
  • My helmet has one 3v cell in a pull out holder, so I don't require this cure, but I have a problem. Why is it that whenever I go to use my welding helmet (which isn't often) the battery is dead? Why is current being drawn when the helmet is just lying there? Should I be storing it in the black bag it came in, for some reason? It is very perplexing because these things have no on/off switch.

    So I took mine apart and there is only one battery…a CR2450 and it tests at 3.18 volts. If I replace it with (2) CR2032 batteries, that’s 6+ volts. Am I going to screw something up?
