A pug cutting machine (commonly referred to simply as a "pug machine" or portable track cutter) is a compact, motorized oxy-fuel or plasma cutting tool used heavily in structural steel fabrication, metal processing, shipyards, and heavy construction. The nickname "pug" traces back to early industrial portable track burners (most notably the classic ESAB Pug series), whose short body, low profile, and sturdy carriage visually resembled a pug dog.
Instead of cutting thick steel plates freehand—which leads to uneven lines and jagged edges—the pug machine acts as a portable semi-automatic guide. It carries a gas cutting torch along a set path at a precise, controlled speed, yielding clean, straight-edge cuts, bevels, or circular shapes with minimal post-processing required.
