Portable, Economical Oxyfuel/Plasma-Cutting System

Monday, May 12, 2014

Esab Cutting Systems, Florence, introduces Crossbow, a compact oxyfuel/plasma CNC cutting system touted for its portability due to its size and weight. It’s recommended for use in trade schools, small fab shops, maintenance and repair shops, or for portable use within large facilities or at construction sites.

Crossbow features a fully integrated CNC, eliminating the need for the user to add a controller to the system. A menu-driven interface and a library of 24 common shapes minimize programming and setup time. For custom programs, the CNC uses basic M- and G-Code programming, and offline programmed NC files can be transferred to the machine using a standard USB connection. Operators can easily set up a step-and-repeat pattern, or load in a nest of shapes through the USB port.

The CNC also features advanced functions including automatic process sequencing, arc-voltage height control, kerf compensation and automatic plate-check. A motorized lifter supports either oxyfuel or plasma torches. Touch initial height sensing finds the plate surface and sets the piercing height during automated plasma cutting. The system also detects torch crashes by sensing the plate during cutting, and shuts down the plasma system accordingly. In addition, a cutting oxygen solenoid valve allows automatic cutting when using an oxyfuel torch.

A precision guide rail enables stable motion of the crossbeam and full support of the cutting torch. Precision linear rails minimize vibration during cutting to ensure accurate cutting over the working envelope. A drive-disengage toggle switch allows quick and easy manual positioning.
