The complex is designed for flash-butt welding in the field environment with pulsed flashing of the rails with cross-section of 6500 mm2 up to 10 000 mm2 with burr removal immediately after welding. The complex is produced in a version of 20ft sea container designed for mounting both on a truck base, and on the railway platform for moving through a railway to the welding works area. If necessary, it can be installed and operated in stationary conditions for manufacturing of rail strings.

K922-1 welder,  crane-manipulator, diesel-generator unit, fire extinguishing system, pump station, control cabinets for welding machine and complex, water cooling post are installed in the container.

For operation of the crane-manipulator, in the container there are rear and side opening boards, doors and hatches necessary for operation of the complex and equipment installation. The crane-manipulator provides for a back out of the welding machine from the container and positioning it on a joint of the rails to be welded. After welding is done by the crane-manipulator, the welding machine will be returned into the container.
