TS 4.20 2D is the abbreviation for the brand new system developed

by Tube Tech Machinery for the cutting and welding of sheet metal.

The system is totally automatic and can trim and weld sheet

metal using a special head which both cuts and welds.

This system has been designed and manufactured

by TTM together with Trumpf and Precitec, who

have supplied some of the parts.

Finally it is our duty to say that, as all themachines at TTM, the TS 4.20 2D wasalso iiigg ee (Finite Elements Method) to ensure tech-nical perfection
