You won’t believe your eyes.

True colour vision –
directly when welding.

For the first time in the history of welding you as a welder see the joining process as it actually takes place. How the weld pool melts, how the weld seam is created. You can see how the filler material is immersed in the welding pool and gain complete control over your work.

CLT offers you brilliant vision, like through a window pane. Crystal clear. And thanks to optrel Autopilot always with the right protection level.

True color means not the same as true color

As far as always the distinction can be seen upon taking a closer look. With the crystal lens technology you will recognize the difference immediately when putting it on.

The color perception in light state is almost like looking through clear window glass and in dark mode you enjoy a detailled and high-contrast view of the welding pool with a never-seen-before clearness.

Simply safer:
working with PAPR system from optrel


  • Integrated particle filters of the highest class (TH3)
  • Reliable protection against smoke, aerosol and dust

You won’t believe your eyes

With light transmission of 31% in bright condition (protection level 2!) welders have for the first time a practically unclouded and clear view of their working environment. This in combination with the almost perfect colour spectrum of the CLT2.0 for the first time allows welders to see what is really going on in the weld pool, and with a clarity that equates to insights into a new dimension. This is why welders describe this as an enlightenment.

<p>Bei ausgewählten expert-Produkten werden speziell beschichtete Filter eingesetzt, die eine bessere Sicht auf das Schweissobjekt ermöglichen. Die Farberkennung durch diese Art Filter wurde so optimiert, dass die Farben der Umgebung fast farbecht wahrgenommen werden können. Somit kann der Schweisser auch ohne Probleme rote LEDs der Schweissmaschine ablesen, ohne den Helm anzuheben was die Effizienz im Schweissprozess und die Sicherheit weiter fördert.</p>
