I have tried researching this, but cannot find any supporting information.
I would like to know if the light intensity from inverter type welders is different to transformer type welders, and if so, what is that difference. I can definitely feel the difference between the two when welding so there must be a difference in their light intensities.
My father, is old school and does not like inverter - his reasoning "it gives arc eyes". I did not believe him at the time, but through many years of trial and error, I do find that even the slightest flash on inverter results in arc eyes, it even got so bad at one stage that I was convinced I was getting flash through the helmet - as a result I added more glass and thicker shades.
I generally even use less amps on the inverter welder, so its definitely not more power = more flash. Could there be a difference in the two light outputs?
