ET20MW3B

DESCRIPTION OF THE MACHINE
ET20MW3B is a fully automatic tabber and stringer machine. Our innovative hybrid welder allows to solder without mechanical and thermal stress, this is indicated for very thin solar cells and for ribbon cells (EFG). The machine is available also with laser soldering system that is indicated also for lead free ribbon. Thanks to the high flexibility the machine is suitable for all types of standard photovoltaic modules but also for BIPV modules.

Patent on soldering system - 10176664.0-1262
