3 – Operation
Step 3: Are the consumables worn?
 Inspect consumables for wear.
 Replace worn consumables.
 Always replace the nozzle and electrode at the same time.
 Avoid over-lubricating o-rings.
 Use genuine Hypertherm consumables to ensure maximum cutting performance.
Step 4: Is the torch perpendicular to the workpiece?
 Level the workpiece.
 Make the torch perpendicular to the workpiece, both from the front and side of the torch.
 Inspect the material to see if it is bent or warped. In extreme cases this limitation cannot be corrected.
Step 5: Is the cut height set at the proper height?
 Adjust the cut height to the correct setting.
 If you are using arc voltage control, adjust the voltage.
 As consumable parts wear, arc voltage settings need continual adjustment to maintain cut height.
 Cut height can impact angularity.
 Negative cut angle: torch too low; increase cut height.
Negative cut angle
Square cut
Positive cut angle
