   • length of track - 18,5m
   • length of welding - 16m
   
5. Welding equipment:
   • GWS can be integrated with MIG/MAG or SAW welding equipment according to particular customer's needs
6. Main technical details:
   • speed of X axis movement: from 0,01 up to 10 m/min
   • the standard version comprises 5 numerically controlled axes, controlled by a computer system with TFT graphic display
   • active compensation of position of both torches with regard to the welding seam with precision of 0,1 mm
   • control system menu in English
7. Control system:
   • GWS is controlled by digital controller
   • the system comprises a high-precision maintenance-free, planetary gearbox
   • all axes are powered by high-class servo motors
   • every servo motor is controlled by a digital inverter
   • high-precision linear guides ensure precise and smooth motion of all system axes
   • the torch holders are fitted on machine's supports through anti-collision joints
   • rigid and heavy duty construction is based on aluminum section profiles
   • GWS is equipped with active safety systems enable protection of the staff
   • system software can be customized to the customer's welding technology
   • depending on a type of welding equipment there is a possibility of registration of welding parameters like current and voltage in a function of time
8. General advantages & benefits:
   • welding process automation
   • increase efficiency and production rate
   • replace time-consuming labour of a couple of welders
   • ensure high-quality welding seams with regular repetitiveness
   • enable multi-layer seams
   • improve working conditions and operator's safety
   • dimensions of gantry and track are tailored to customers' requirements

Most of technical specifications can be customised. One of PROMOTECH'S main advantages is its capacity to manufacture purpose designed and custom built systems.
