Workpiece clamping system for welding machine has multiple clamping elements and welding tools moving toward workpiece support tables

摘要

A knee-joint clamping system (14) has a mechanism (30) which may be mounted on a shaft (34) so that the whole assembly may be rotated. A lever (36) carries a clamp and holder (16) for a welding element (18). The welding element may be moved toward a workpiece support table (26) on a mounting element (24).
