ProStar™ Gantry System

Get a Grip on Productivity Demands

Extremely high-deposition ProStar™ GWS automated gantry systems are used for longitudinal welding of long structural beams, and built to order for each customer. ProStar welding gantries are built with the user in mind. An intuitive touchscreen HMI with aviator style joystick easily control all gantry functions. Set low to the floor, a moving, high-back operator’s seat offers comfort and safe proximity to the work area. Additionally, all PRSGWS gantry systems come complete with two welding stations, weld-seam tracking, camera systems and torch adjustability.
