Sanden Goggles

admin

I realize that these goggles are not produced in the US, but I am wondering if anybody would have any idea on how to obtain them.  One of the students that I am working with is a Norwegian foreign exchange student, and he was baffled when neither I nor my boss knew what Sanden goggles were.  I searched online and was unable to find them anywhere.Here is what Wikipedia has to say on Sanden goggles:"In 1970, a Swedish doctor, Åke Sandén, developed a new type of welding goggles that used a multilayer interference filter to block most of the light from the arc. He had observed that most welders could not see well enough, with the mask on, to strike the arc, so they would flip the mask up, then flip it down again once the arc was going: this exposed their naked eyes to the intense light for a while. By coincidence, the spectrum of an electric arc has a notch in it, which coincides with the yellow sodium line. Thus, a welding shop could be lit by sodium vapor lamps or daylight, and the welder could see well to strike the arc. The Swedish government required these masks to be used for arc welding, but they were not used in the United States. They may have disappeared."Otherwise, I have not been able to find any info on where I could find these goggles.  They sound awesome and potentially really helpful to some of our beginner welders.  Even a source to the lenses could be useful.  Thanks!-zoruss
Reply:Good luck, does sound interesting.  The multi-layer bit sounds like a dichroic filter, which is used in some welding filter designs. Unfortunately I did not see any other mention of Sanden Goggles (specifically reference to sodium vapor lighting)Maybe try using Swedish Google (they have regionalized versions I believe) might help-- fredLincoln 180C MIG
Reply:Thats pretty cool... Around here, most people just flip their hoods down and then "blindly stab" until the arc is struck, and then move the rod into position. I sure would like to try one of these setups, tho...[Account Abandoned 8/8/16 Please Do Not Attempt Contact Or Expect A Reply]. See you on YouTube! -ChuckE2009
