4.09 RECOMMENDED CUTTING SPEEDS
Cutting speed depends on material, thickness, and the operator’s
ability to accurately follow the desired cut line. The following
factors may have an impact on system performance:
• Torch parts wear
• Air quality
• Line voltage fluctuations
• Torch standoff height
• Proper work cable connection
This information represents realistic expectations using recom-
mended practices and well-maintained systems. Actual speeds
may vary up to 50% from those shown.
