I went and got a new one.
The old one lasted maybe 5 yrs, it gradually lost the ability to darken immediately.
Was talking to a bud at work and he said they have to have batteries in them. But they are sealed- glued shut.
The lens holder can be pried out ( work on opposite side of darkness dial).
The big trick it to NOT cut yourself with the box cutter tool you need to use. ALWAYS aiming the blade AWAY from you!!
I lightly set it in in my vise so I could score the parting line and do some prying.
This worked.
The batteries have spot welded tabs that need to be broke off ( both sides).
Again, the cutter goes under the tabs and twists each side until they break.
If I did it again- I would test each batt. because one of them was still good- had 2 something volts.
I found a watch battery in my drawer close in size to put in place of the bad one.
The tabs that were on the battery make decent contact leads for the replacement juicer.
Held the thing near a bright light and presto- it works.
Taped it back together and re-installed in the old helmet.
I really have liked the HF helmet.
Am a pro welder and have expensive ones at work.
The Miller hood at work has 4 sensors ( a big plus) but needs to have the reset button pressed or U get flashed first strike, (supposed to be auto start) and the other one has a manual on off (but can be used for cutting torch work- a plus) .
Both of these guys cost hundreds of bucks, yet I like the HF just as well.
The design devils did real well making the HF only last several years and you gotta buy a new one.
This is one guy that beat them. Now you know their trick too.
They easily could have made these batteries changable.
Oh well.
