About Cavitar ArcLess Academy
Weld Education 2.0
Traditional ways of weld education such as books and classes are slowly becoming only a small portion of today's world. With the advancement of Web 2.0 and the interactive nature of new teaching platforms on the internet such as YouTube, the youth of today are always looking for the newest and best ways to enhance their knowledge. While videos are a great supporting tool in weld education, the big bright process light makes it impossible to see what you are actually welding, which means you need to rely on your spatial understanding of the process during the welds and have to resort to imagination of how the weld looks in real life at that moment. This is why we created Cavitar ArcLess Academy, a completely new concept of teaching welding without any bright light in the way. This view is possible by using laser illumination technology from Cavitar. We like to be the first to welcome you the new world of weld education, which we call "Weld Education 2.0"
