The carbon steels referred to have already been extensively researched on Armour plating by the University of Wollongong. Interesting that Ktig is not using their research. I also cant find any successful results regarding carbon steel anywhere on the website. While being able to weld carbon steel may be valuable, they don't seem to have publishable success as yet. big market claim with no supporting evidence.

Sounds like a glossy sales pitch rather than anything of substance.
