Taking apart a MetalMan auto-darkening welding helmet, replacing the batteries, and modifying it so that batteries can be replaced again in the future. This is an older model from Tractor Supply that wasn't made to have serviceable batteries. The newer ones are designed better.

Got me back on the job inside 30 minutes when I thought I was gonna lose a day waiting for a new part. Big thumbs up!

Thanks for doing this. I pulled my helmet apart and put new batteries in it, and now it works again. You can use 2032 batteries.

Thanks for the video. my helmet stoped working ,and i did your procedure ,but instead of installing new battery’s I soldered in a cr-123a battery holder mounted to the inside surface of the helmet.. now i can replace battery’s anytime i need without removing or taking anything apart.

Thanks for the video, sir! Mine was a Lincoln 1840 that was a “gift” that came with my welder. The internals were a little different. I needed to put a strip of electrical tape around the edge of the batteries. Also, no room from screws so I just used a Gorilla tape to hold it together. Thanks again.

I used 2 AAA batteries and soldered a battery case from an old remote. Figured AAAs are easier to find than those flat batteries. Works as well. Thanks for the idea.

I ran into that problem today. Even though I knew what the problem was, I wasn't sure if it would ruin it if I opened it. I was about to go buy a cheap one tomorrow but I found your video and I replaced them with 2032. It works. You helped me save about $60 and I saved an extra 15% by switching to Geico..😎

Thanks for this. I love the shield I have and really didn't wanna get a new one.

Have same hood basically but from hf. Thanks for giving me a look at the board and what the problem is. Going to modify mine to have the batteries on the outside of the plastic shell

Pro TIP: Don't try to solder onto CR2032 batteries, use hot glue or tape to keep them together and also use wires instead of those metal bullshit so you can take them outside the enclosure. I couldn't get the solder to stick and eventually blew one up. Not a big deal. Just to save you hassle of sanding and realizing it won't stick unlike AA batteries.

Good video! Thanks for the info!

Thanks. I have the idea to do a modification with such a thing. The idea is a manual switch to enable darkening mode so you can just turn it on when you're about to weld. This way I can prevent the short flash just before it is getting dark, which is so annoying.

done this, cheers , used 2x 3v 2016 which i had laying around , i just desoldered the metal clips from the board and put some wires there instead probably quicker , i realise probably not rechargeable cells i put in but will change to correct cr2430 when the cells die
