Using the machine torch
Since the Powermax with a machine torch can be used with a wide variety of cutting tables, track burners, pipe bevelers,
and so on, you will need to refer to the manufacturer’s instructions for specifics on operating the machine torch in
your configuration. However, the information in the following sections will help you optimize cut quality and maximize
consumable life.
Setting up the torch and table
• Use a square to align the torch at right angles to the workpiece in two dimensions.
• The torch may travel more smoothly if you clean, check and “tune” the cutting table’s rails and drive system.
Unsteady machine motion can cause a regular, wavy pattern on the cut surface.
• Ensure that the torch does not touch the workpiece during cutting. Contact with the workpiece can damage the
shield and nozzle and affect the cut surface.
Understand and optimize cut quality
There are several factors to consider in cut quality:
• Cut angle — The degree of angularity of the cut edge.
• Dross — The molten material that solidifies on the top or bottom of the workpiece.
• Straightness of the cut surface — The cut surface can be concave or convex.
The following sections explain how these factors can affect cut quality.
Cut or bevel angle
• A positive cut angle, or bevel, results when more material is removed from the top of the cut than from the
bottom.
• A negative cut angle results when more material is removed from the bottom of the cut.
