McElroy’s TracStar® 500 will butt fuse pipe sizes from 6” IPS to 20” OD (180mm to 500mm). It was the first fusion machine in the world to be mounted on a track system, making it mobile in almost any terrain. Considered the flagship of McElroy machines, its success spawned the entire TracStar line of fusion equipment.

Pit Bull® 500 Series II
• Compact fusion for special applications
• Hydraulic Power Unit (HPU) sold separately
• DataLogger® compatible

The Pit Bull 500 is used for special applications where the tracked vehicle is not needed. These machines can fabricate segmented ells with optional mitered inserts and are DataLogger® compatible.


The TracStar 500 incorporates the interchangeable 500 carriage with McElroy’s patented Centerline Guidance System. Two fixed and movable clamping jaws result in precision pipe alignment for higher quality fusion joints.

The Automated TracStar 500 is also available with automated control and monitoring over the heat, soak, fuse, and cool cycles. This automated system guides the operator through a step-by-step procedure for fusing pipe. It has a built-in datalogging feature that keeps a record of each fusion joint, which allows you to verify joint integrity.
