[Shop-talk] Welding auto-darkening helmet

[Jack Brooks]

Dave,

On my helmet, which is a HF helmet, I found the batteries.  The very bottom
of the electrical assembly has a small raised tab on the right side. This is
on the lowest portion of the electrical assembly, facing directly back at
your face. Pushing this left and lifting reveals two AAA batteries.  it is
basically a snap on access panel.

This may be easier if you remove the two thumbscrews holding the entire
electrical assembly in place, just as you would do if you were going to
change out the clear glass on the outside of the helmet and them pull the
assembly out of the helmet entirely. 

Jack

When you figure out how, please let us know.  I have a couple of them at 
school.

One way I test the helmet is to strike a flint striker in front of it.  
That usually causes it to darken.
