3 – Operation
 Positive cut angle: torch too high; decrease cut height.
 A slight variation in cut angles may be normal if the variation is within tolerance.
Step 6: Is the cutting speed set too fast or too slow?
 Adjust cutting speed as needed.
 Cutting speed may also impact your dross levels.
 High-speed dross: The cutting speed is too fast and the arc lags behind. Reduce the cutting speed.
 Low-speed dross: The cutting speed is too slow and the arc shoots ahead. Increase the cutting speed.
 Top spatter: The cutting speed is too fast, reduce the cutting speed.
 In addition to speed, both material chemistry and surface finish can impact dross levels. When the workpiece heats
up, more dross may form on subsequent cuts.
Step 7: Are there problems with the gas delivery system?
 Identify and repair any leaks or restrictions.
 Use properly sized regulators and gas lines.
 Use pure, high-quality gas.
 If manual purge is required, such as with the MAX200, confirm that the purging cycle was completed.
 Consult the gas distributor.
Step 8: Is there torch vibration?
 Verify that the torch is securely attached to the table gantry.
 Consult the table manufacturer, your table may require maintenance.
Step 9: Does the table need to be tuned?
 Check and ensure that the table is cutting at the specified speed.
 Consult the table manufacturer; the table speed may need tuning.
