4.1 cut Quality
a. Introduction
Causes affecting cut quality are interdependent. Changing one variable affects all others. Determining a solution
may be difficult. The following guide offers possible solutions to different undesirable cutting results. To begin
select the most prominent condition:
4..
4..
4..4
4..5
Usually the recommended cutting parameters will give optimal cut quality, occasionally conditions may vary
enough that slight adjustments will be required. If so:
• Make small incremental adjustments when making corrections.
• Adjust Arc Voltage in 5 volt increments, up or down as required.
• Adjust cutting speed 5% or less as required until conditions improve.
B. cut angle
negative cut angle
Top dimension is greater than the bottom.
• Misaligned torch
• Bent or warped material
• Worn or damaged consumables
• Standoff low (arc voltage)
• Cutting speed slow (machine travel rate)

Before attempting anY corrections, check cutting variables with
the factory recommended settings/consumable part numbers
listed in process Data.
