The clamping sequence of the clamping fingers can be specified individually or groupwise in the machine control.

The step-by-step process of a defined clamping sequence enables several short components to be inserted in turn, which saves time during the clamping and welding cycle. For special parts with interrupted welding sections too, type V is a good solution since the sections are clamped in turn and can be aligned with zero gap.

Series with maximum welding length from 600 – 3,100 mm.[/vc_column_text][vc_column_text css=”.vc_custom_1524086913330{margin-bottom: 30px !important;}”]
