Portable track cutting machines perform a variety of tasks including torch cutting, welding and plasma, depending on what rigging and accessories they are fitted with. QCC portable track cutting machines move at a controlled, variable speed and are powered by a reliable electric motor and belt drive system. The machine drives in a straight line on “V” groove track for precise control, plus tracks can be stacked to allow for longer lengths of travel. Track cutting machines are capable of supporting oxy-fuel cutting, arc welding and plasma cutting and can be outfitted with two or more oxy-fuel torches for cutting multiple or compound bevels in a single pass.
