2. Features and performance
        The main machine include a framework, 4 sets (8 units welders) Co2 welding heads pneumatic arc guide device, 8 units Co2 Kemppi welders, Co2 wire feeding device and welding heads, Co2 air supply device and so on.
        Main framework adopts double sides synchronous driven, there is installed Co2 welder, wire feeding device, wire drum, water cooling device on the top off main framework.
        Co2 welder is consist of welder source, wire feeding device, automatically welding head, cooling system, Finland Kemppi PRO4200 sires welder with water cooling welding head and four-wheels wire feeding device, it can ensure large current continue welding, maximum welding current is 400A.
        There are 4 sets arc-guide device on the top of linear guideway (electrical adjust the position), each arc guide device is set with a couple of pneumatic lift and clamp wheel to ensure Co2 welding heads aimed at the welding seam, in order to ensure the two face to face welding heads synchronous arcing when subsection welding, they will be dis-placement arrangement on the both sides of arc guide wheel, the adjust distance is 350mm or 450mm.
        On the bottom of main framework, there are two sets beams, they adopt with frequency motor to control the speed, step less adjust the speed during the welding process. PLC control all the working step, 24kg/m guideway.
