Trac-Bug Compact Friction Drive Cutting Machine
The Trac-Bug is a compact friction drive cutting machine that will ride on any standard 6" (152 mm) V-grooved track. A solid-state variable speed control allows the Trac-Bug to travel and carry a torch at precise speeds producing a machined quality cut or bevel. Plate cutting and welding preparation can now be done quickly and with a high degree of precision. Quality bevels produced with the Trac-Bug reduce fit up and grinding time and lay a foundation for a stronger weld. The Trac-Bug... (read more)
