If you've got a HF welding helmet that's quit working try this ----

I have 2 of them but one is so old that it doesn't come apart so easy as the one shown which is the same as my 'newer' one.
I got the Radio Shack battery holders and de-soldering braid and went for it with the 'new' (5-10 years old) helmet - BEHOLD ...... it WORKS!
Since the helmet has a built in solar charger I've ordered 4 [b:7f02cc589e]rechargeable[/b:7f02cc589e] AAA batteries - don't know yet if that will work, but in the meanwhile the Coppertops are easy to change and I don't need a new helmet!
