Hi guys !
I bought a welding helmet (no name) and a couple glass lenses with 11 & 12 shades.
The lenses have the AULEKTRO brand printed on them like this:
AULEKTRO 11 FW 2 DIN GERMANY.
AULEKTRO 12 FW 2 DIN GERMANY.
After googling for AULEKTRO, i've found a website where there was no reference to the FW 2 type of lens, only FW 1 was mentioned, therefore I am worried if this lens is suitable for stick welding (smaw) it might be intended for torch welding/brazing or it might be a counterfeit part, and I want to be sure not to fry my eyes.
I did some testing of the lenses by looking at a lit light bulb, here are my observations:
1) By looking through the lens which came with the helmet & had no markings on it, the filament appeared reddish.
2) By looking through the AULEKTRO lenses, the filament appeared greenish yellow with a barley noticeable shade difference between the 11 and 12 shades.
Which lens seems to be a good one ?
I also did try to check the IR protection by using a remote control, and it only reduced its working distance and the remote was still working one or two meters away from the TV....isn't it supposed to block/filter ALL IR light ? the invisible beam of a remote control has a tiny power compared to stick welding light, is it normal ???
Please help, any input is welcome.
Thanks !
