PRODUCTS
1PB / 1PC / 2PF series, 250 kg to 1000 kg capacity
A positioner turns the workpiece into a favourable welding position and is a key part of a robotic welding cell. The DAIHEN (OTC) product centre lists three positioner series: 1PB and 1PC provide single-axis rotation, while 2PF adds tilt. Capacity covers 250 kg to 1000 kg with ±0.05 mm repeatability.
Models and configurations follow the technical documentation shipped with the equipment. Please confirm detailed specifications with our engineers.
