Voortman uses the Voortman's torch nozzle. The nozzle is specially engineered to last 3 - 6 month depending on how hot your machine runs. The torch nozzle is difficult to bend due to the head breakaway that deflects it. The heat of the gases through the nozzle eventually causes nozzles to become worn. Replacement torch tips are available for $75 per tip.
Programming of the CNC Beam Coping Machine is very simple even when done manually. The machine programming software is Peddimat and most operators can learn how to program most parts in less than an hour. Of course practice makes perfect. However the best way to program the machine is to import parts directly from a CAD drawing preferably done in some 3-D modeling software such as Tekla Structures, SDS/2, ProSteel 3D, StruMis etc. These files import directly into the machine. In some cases the operator might need to edit the part program to create a lead out to ensure smooth cutting and then he merely selects the part to be processed and hits the Cycle Start button.
