I was welding at 50 amps and haven't experienced any arc flashing while welding other pieces at this setting, hence why my initial question was in regard to whether the flash had something to do with the specific weld I was trying to accomplish. I'll be putting a new battery into the helmet later to...

Yes, the Speedglas does have a red, sensitivity adjusting knob inside the helmet.

Wow, now THAT’S touchy! How old is the Miller helmet you’re talking about? I don’t know the history of the Speedglas XL I have, so can’t really comment on it. To boot, it’s the first and only helmet I’ve used to date. I just put a load on the battery and it appears drained (.03 output,) so I’ll star...

I just tested the battery and it's putting out 11.3 volts (it's rated at 12 volts) so it appears the battery is still good...

The Speedglas has batteries in it...they were the first things I replaced when I got the hood. I suppose I could and should check them though, as they're now probably 1 to 1-1/2 years old. But I'm ready to invest in a new helmet, so...recommendations?

Hah!...interesting that I was looking at new hoods right when you posted this. There wasn't anything blocking the sensor's when I was welding. I was leaning slightly over the table, in an open space. I was fairly close to the work, so the sensor's shouldn't have had any problem picking up the light....

Yes, the hood was turned on. It's an older Speedglas and I've made it a habit to test it every time I'm about to use it. This time I even had it set all the way up to it's highest setting, number 13. Covering all bases, have you turned the auto hood on? First time I used one I didn't know I had too....

I finished that piece by brazing with silver solder, so I'll have to make another piece before I can take some photos. The flashing I'm referring to is that the arc was so bright that even with my helmet set at 13 it was too intense for my eyes, so I only had the torch turned on for a second. The ro...

I'm making stainless steel jewelry. Both pieces are 316L stainless. The first piece is a ring fabricated from 3/16" stock. It has 3/32" holes drilled into it. 3/32" rod is slipped into the holes, and I'm basically trying to tack the two pieces together from the backside. The 3/32"...
