OTC-Daihen - ECO-ARC 200 / ECO-ARC 200L - Stationary Arc Welding Robot Arm Work Table and Cell

NEW Robotic Weld Cell

OTC-Daihen Dual Station Robotic Weld Cell

The OTC-Daihen ECO-ARC robotic weld cells are the simplest solution for welding small parts.  Period.

The ECO-ARC are dual-station positioning cells designed for welding small and medium parts with the simplest operator intervention.  Each station on the ECO-ARC 200 model features large 24" x 32" tables with a 2,000 lbs payload capacity. The ECO-ARC 200L model allows welding of larger parts, made possible from 36" x 48" table with 2,000 lbs payload capacity. While the operator prepares the next workpiece, the robot welds on the opposite side. Plus, the ECO-ARC's has a new compact design, which makes it ideal for busy shops with small-to-medium-volume production schedules. 

All ECO-ARC weld cells are shipped pre-assembled, so you don't have to worry about the hassle of a prolonged and involved installtion. It's quick and simple.  You can have your new weld cell out of the box and ready for used in just a few hours.
