Thanks guys,

So when welding for long periods of time one could use three sets of glasses (2 dydinium + 1 blue) simultaneously or the TM2000 lense. Then a single lense is easier.

When welding with shade 3 lenses for short periods of time, one is getting a bit in the twilight zone of things. Or is shade 3 just to low even for short periods. Welding up a panel takes some time.

I can buy a set of older TM lenses second hand. Is there a big difference between a 2013 set of earlier models?

Thanks for the information,
