Two-Axis Positioners
Drop Center
The Drop Center positioner adds an additional axis to a head and tailstock positioner to weld parts that require complex manipulation during the weld cycle. The two-axis make it possible to manipulate a part to achieve “in position” welds.

Drop Axis
The Drop Axis positioner adds an additional axis to a headstock to weld parts that require complex manipulation during the weld cycle. The two-axis make it possible to manipulate a part to achieve “in position” welds. The Drop Axis offers substantial robot access to complex parts.
