This System is Self-contained and fully enclosed, shipped ready for service. The design of the enclosure and base provides for the unit to be mounted as a static plant welder or installed directly on a truck chassis (or flat wagon of a proper height) for mobile operation in-track.Learn More
The Narrow Head Flash Butt Welder is tall and narrow, requiring only 8.5 inches of clearance from the adjacent rail or fixed object. This allows for completing a flash butt weld inside of a turnout in transit areas, where flash butt welds were impossible in the past and even thermite welds were difficult.Learn More
