Perfect View at Welding process – Only from optrel:

  • Fully-automated Adjustment of the Shade Level to every Welding Application in between Shade Level Range 5 to 13.
  • True Color View in all Shade Level Range.
  • Ultra-HD Quality at Optical Classes 1/1/1/1


The adaptive shade level adjustment puts on the optimum shade level fully automatically in between the range of 5 to 13.

This is done by an additional brightness sensor, measuring the intensity of the welding arc.
You are always perfectly protected, whatever welding parameters you are using.
Manual adjustment isn’t necessary, but sure also possible at the tip of your finger.

* The autopilot can be shut off on demand and the shade level can be adjusted manually if favorded.

The Fully Automatic Machine in Ultra-HD Quality.

True Color View

A special UV-/IR-Filter developed by optrel enables the typical real color view of the optrel ADF and brings colors into the world of the welder.


4 Times Highest Class

The optrel e684 ADF proofs the highest level of image quality in all 4 classifications:

  • Optical Class: Class 1
  • Scattered Light: Class 1
  • Homogenity: Class 1

Experience the difference.

The welder is recognised as the top athlete among the metal craftsmen. They need to cope with harsh work conditions such as fumes, constantly changing levels of brigthness and heat. Additionally, welders have a high level of responsibility. A flawed welding seam might, in extreme cases, be the cause for deadly incidents. 

Hence, a perfect welding helmet becomes increasingly important. It makes the weld process safer, more efficient, more accurate and more comfortable. Therefore only the best is good enough.

So do not settle for anything less!
