The visor stays at DIN 4 in the light state and shifts to DIN 9 - 13 when welding starts, so you are not constantly lifting the helmet between checks and welds. That makes day-to-day work a bit smoother and safer at the bench or on site.\nIt suits general welding work where you need reliable eye protection and quick reaction from the lens. Handy for garage use, fabrication work, repair jobs and workshop tasks where the arc starts and stops regularly. The 90 x 45mm viewing field gives a practical working view without overcomplicating things.\nSwitching time from light to dark is 1/25000 sec, with a 0.4 sec delay from dark back to light. Sensitivity is adjusted inter5
