3.11 CUTTING SPEEDS
This Section contains information on cutting speeds for hand
and automated applications with PCH/M-150 Torch. The
information is organized into two subsections as follows:
A. Hand Cutting Speeds
B. Automated Cutting Speeds
Each subsection contains cutting speed charts for various
plasma and secondary combinations on different materi-
als.
The following factors may have an impact on system
performance:
• Torch parts wear
• Plasma and secondary gas quality
• Operator experience
• Torch standoff height
• Proper work cable connection
• Alloy content of material
• Hand Cutting Notes
Hand cutting speed depends on material, thickness and
the operator's ability to follow the desired cut line.
The speed charts show the optimum cutting speed
ranges with various plasma and secondary combina-
tions. The data was obtained using a machine torch
with the recommended 1/8 inch (3 mm) standoff.
The hand cutting information represents realistic
expectations using recommended practices and well
maintained systems. Actual speeds may vary up to 50%
from those shown for hand cutting.
• Automated Cutting Notes
Automated cutting speed depends on material, thick-
ness and how well the system has been maintained.
The automated information represents realistic expecta-
tions using recommended practices and well-main-
tained systems. Actual speeds may vary from those
shown in the charts depending on the alloy content of
the selected material.
