I learned to weld on a sliding gate, and the gate caught fire. Not the whole thing — patches of it — and I was standing in my own driveway with a cheap flux core welder throwing sparks everywhere, thinking what am I doing. The YESWELDER LYG-M800H I bought with the machine is the reason that afternoon stayed fun instead of becoming a hospital story. That was May 2022. Four and a half years later I’m still wearing the same helmet, still on the same lens and filter, and I’ve never welded a single thing without it.

Is the YESWELDER LYG-M800H worth it after four and a half years?
Yes. If you’re doing flux core on car bodies, gates, gym equipment, whatever metal breaks around the house, this is the cheapest part of your setup and the one that keeps you welding. It darkens when the arc starts and clears when you stop, which is the whole point. It is not for someone who wants a static always-dark lens — buy a passive hood instead. I’d buy it again today at full price, and I did pay full price for it back in 2022.
What held up:
- Same lens and filter after 4½ years, no darkening spots, no dead zones
- Survived at least two drops — scratched, never cracked
- Solar cell plus internal battery: it recharges off the arc, so it works in a dark garage
- Headgear and shell still all there — nothing cracked, nothing taped
What didn’t:
- The adjustment dials bite — loosening and re-tightening every time, about a minute, every time
- No raised edge around the front cover lens, so a drop goes straight into the glass
Why I bought it
I had no welder and no helmet. I bought both in one order and taught myself on scrap. So there’s no “I switched from X” story here — this was the first auto darkening helmet I ever put on, and I had nothing to compare it against except other people’s rigs I’d watch from a distance.
What sold me was the size of the window and the shade range. A 3.94″ x 3.66″ screen is big enough that you’re not hunting for the puddle through a slot, and the shade knob goes from a light grind setting all the way to 13. When you’re learning, being able to see where the wire is actually touching is the whole game.
While I’m on the car work: the other half of the same problem is stuck fasteners, which is why I wrote up the Ford truck bed bolts that stripped on me. Rusted steel is rusted steel, welded or threaded.
What four and a half years of flux core welding has been like
I use it maybe monthly, sometimes weekly, depending on the project. Cars mostly. Anything on a car I weld. Fitness equipment that cracks — welded. Metal that needs joining — welded. I run flux core because it’s what my machine does, and I don’t care that it’s not the prettiest process. Ugly welds still hold.
The most recent job was a floor patch on a 1969 Firebird. That steel is thin enough that a cheap flux core setup will blow holes straight through it, even on the lowest wire setting. The trick I use: let the wire stick two to three inches out of the nozzle and weld from that far away. It keeps the heat spread out, and you can run the whole patch without burning through. I did the same thing on the gate in 2022, badly, and it’s still hanging.
Through all of that — the learning curve, the fires, the Firebird — I’ve never once found a reason to take the hood off and look away from the arc. It darkened when it needed to and cleared fast enough that I could reposition without lifting it.
The batteries do run down if it sits a while. It’s rechargeable, and it also charges off the arc itself while you weld, so a dead helmet comes back the moment you start striking. That matters if your garage is dark or you’re working outside at dusk.
What I’d change
Two things, both about the shell and the headband.
The tightness adjustment is the small annoyance that never goes away. There’s no quick-release — if you want it to sit right, you loosen the side dials, seat it on your head, then tighten it back down, every single time. You can just rip it off, but then putting it back on means doing the whole ritual so it doesn’t slide off mid-pass. It’s under a minute. I still notice it every time.
The second one cost me a lens. There’s no raised or beveled edge around the front cover lens, so when I dropped it, the glass took the hit directly. It scratched. It didn’t crack and I’m still using it, but a lip around the window — like a lot of cases have — would have taken the impact instead of the plastic.

You get a shade knob that holds a grind setting and a weld range. Here’s the ladder, with where I keep mine:

Who should skip it
If you want a passive lens — always dark, no sensors, no batteries — this is the wrong hood and you should go buy the cheap fixed-shade kind. That’s the only reason I’d steer someone away. The other fit limit is the adjustment ritual: if you’re pulling your hood up and down dozens of times an hour on a job, the dials will wear on you.
FAQ
What shade should you run for flux core welding?
I keep mine cranked to 13, the top of the range, because I’d rather over-protect my eyes than squint at a puddle. Shade 10 or 11 is what a lot of people run for thinner work. The 9–13 range on this helmet covers both, and there’s no wrong answer as long as your eyes aren’t sore after a session.
Are you supposed to be able to see through a welding helmet?
Yes — before the arc starts, and once it stops. This one sits light enough to see your work piece, tack your wire, and line up the joint while it’s waiting. The moment you strike, the sensors darken it. You should not be able to see the arc itself, and if you can, turn the shade up.
Do the batteries actually last, or does it die mid-job?
Mine has run down sitting in the shop and come back the moment I started welding — it charges off the arc, and it’s got a solar cell on the front too. In four and a half years it has never quit on me in the middle of a pass. If it’s been in a drawer for months, don’t count on it waking up instantly.
Bottom line
Four and a half years, one scratched lens, zero injuries, and a Firebird floor patch I’m still proud of. If you’re learning flux core on old cars and you need a hood that just darkens and gets out of the way, this one has done that job for me since 2022. see it on Amazon
