Another problem is that the flame can blow back when cutting thicker parts, even with light-wide-flange beams. This can cause damage to the plasma head.
The basic unit is semi-automatic, with oxy-fuel coping machines. The operator positions and finetunes the workpiece before it is cut. The laser can also be set up automatically to auto-probe and adjust the torch height. The basic unit has powered conveyors. Before cutting, the operator must manually measure and mark X on the feedstock. The optional laser measuring of the feedstock can also be used as an automated measurement system. The interface allows the operator input the material type to which they want to cut. The operator navigates through a variety of options by using the touch screen to see pictorial representations. The computer program includes all dimensions of structural steel AISC. A fully dimensioned deal drawing is displayed to simplify programming, save time and reduce operator input errors. The operator has the ability to modify or override the input. It can also be saved as an additional program, if needed. DSTV exported drawings can also be used to pre-programme your machine. An operator can use the wireless remote control to operate, start, stop and manage the equipment. The wireless remote control allows the operator to easily view the equipment from any angle that is needed to verify and maintain accuracy. Operator marks the material, moves the material in the right position and clamps it hydraulically to ensure that the material is cut correctly. The laser operator aligns the laser to the mark, then begins the process. The torch lightens and pre-heats the material. The operator initiates and finishes the cutting process, as long as he maintains the correct torch height.
