Replace battery in Harbor Freight "solar" powered welding helmet
Yes, the solar powered welding helmet does have two coin cell
batteries in it. They're sealed in the lens's case. Someone wrote up the procedure for replacing them a year or so ago, and I didnt' save the page then. I googled for it, but came up empty handed. Did anybody here save that web page, or has anybody here disassembled their HF autodark helmet to replace these? RWL |
Replace battery in Harbor Freight "solar" powered welding helmet
I've had 2 HF a/d helmets for 6 years-never needed to replace the
batteries-yet. I remember the thread, but not the details. But, c'mon, yer a smart guy, right? You don't really need to be shown, do you? Hmmm?

RWL I wasn't the one who posted about the repair but I did replace the batteries in mine. I went to Radio Shack and bought two coin cell holders and the cells to fit them. I then carefully split the case with my pocket knife, removed the two dead batteries, and soldered wires to the circuit board where the batteries used to connect. Then mounted the new cell holders on the outside of the case, soldered the wires to the holders, and put the case back together. I don't remember if I glued the case or just heat sealed it with an iron. Anyway, the cells are now on the outside and can be easily replaced when they need to be. The cells do ot fall out of the external holders. Eric |
Replace battery in Harbor Freight "solar" powered welding helmet
this from dec 2010
================ First posting in joining.welding, I hang out over rec.metal. My cheapy autodark helmet quit recently, about 3 years old. I Googled autodark helmet repair and did not find much, except for this thread: http://groups.google.com/group/sci.e..._thread/threa= d/d5797c5c51780adf/365364320493c325?lnk=3Dgst&q=3DAuto+dark+welding+h elmet+= failure#365364320493c325 Hence the cross posting. Summary of which is: all autodark helmets w/ solar cells also have batteries, not they have capacitors, batteries,=85blah, blah, blah=85.Store your helmet in the sun to extend the battery life. The advice was a bit late but I placed the autodark module in a southern facing window for 9 weeks. On the first strike the autodark was noticeable slow, but was OK for the following restrikes. After a 5+ minute pause, the first strike was once again slow. With not too much to loose, I used an Exacto knife and cut open the case seam: http://i290.photobucket.com/albums/l...chining/Autod= arkopenedcr2330batt.jpg Two CR2330 batteries soldered to the board. I found a replacement battery w/ the solder leads attached http://parts.digikey.com/1/parts/125...m-w-legs-br-2= 330-vcn.html but then I thought why not mount the batteries on the outside of the case as in this simulation http://i290.photobucket.com/albums/l...odarkmodulew-= externalbatt.jpg There is plenty of room between the module and my forehead for the batteries. So should I stay w/ the 0.255mAh CR2330 battery or go with something else since I am no longer constrained by the package space? If so what? I found this puppy w/ a much higher capacity http://parts.digikey.com/1/parts/121...w-pcterm-cr-2= 477-hfn.html but it also has a higher self discharge rate. SO where does one go to buy a very small qty of electrical components today? In my youth I stopped by Radio Shack or Olsens Electronics for parts. I found a nice looking battery holder online (in min qtys of 12). I need a battery holder that I can bond or screw/rivet to the PP (guess) case of the autodark module. Who are some good vendors that are willing to deal in small qty orders and don=92t have outrageous shipping rates? ================ -- Christopher A. Young Learn more about Jesus www.lds.org ..

We had our first evening welding class last night and one of the young guys mentioned that his HF autodark helmet quit working. I told him I that I had seen a procedure somewhere on the net describing replacement of some batteries inside the one with a solar cell. I couldn't find it when I Googled last night. I was hoping one of you guys might have saved it or the URL. Knowing that it's repairable, I could probably muddle through and do it on my own, but the voice of experience is always helpful rather than having to reinvent the wheel. RLW |

I was going to use my helmet to look at the Venus crossing and discovered it was dead...after a few years of non-use in the garage. Ridiculous they don't make the batts accessible/changeable. Cheers, and thanks for the info. |

If it does, stick the helmet in the sun for a day or so. DO NOT TRY TO QUICK CHARGE IT. Mine's been in the box for about a decade. Just tried it and it seems to work, but the next time the sun shows, I'm gonna set it outside in the sun for a while. One thing that concerns me is that you're putting 4.5V on a 3V system. Have no idea what does to the phase shift of the liquid crystal and how that affects the attenuation of the light. It's unlikely that it's a problem, BUT, it's your eyes and a mistake could be very costly. Tread carefully while you can still see. The UV will be blocked no matter what the liquid crystal shutter does. Its function is to block visible light. Eric |
