Varying the gouge profile
The following actions have the stated effects on the gouge profile:
• Increasing the speed of the torch will decrease width and decrease depth.
• Decreasing the speed of the torch will increase width and increase depth.
• Increasing the standoff of the torch will increase width and decrease depth.
• Decreasing the standoff of the torch will decrease width and increase depth.
• Increasing the angle of the torch (more vertical) will decrease width and increase depth.
• Decreasing the angle of the torch (less vertical) will increase width and decrease depth.
• Increasing the current of the power supply will increase width and increase depth.
• Decreasing the current of the power supply will decrease width and decrease depth.
Common hand-cutting faults
The torch does not cut completely through the workpiece. The causes can be:
• The cut speed is too fast.
• The consumables are worn.
• The metal being cut is too thick for the selected amperage.
• Gouging consumables are installed instead of drag-cutting consumables.
• The work clamp is not attached properly to the workpiece.
• The gas pressure or gas flow rate is too low.
Cut quality is poor. The causes can be:
• The metal being cut is too thick for the amperage.
• The wrong consumables are being used (gouging consumables are installed instead of drag-cutting
consumables, for example).
• You are moving the torch too quickly or too slowly.
The arc sputters and consumables life is shorter than expected. The cause can be:
• Moisture in the gas supply.
• Incorrect gas pressure.
• Consumables incorrectly installed.
