APPENDIX
APPENDIX 2: CUTTING SPEED CHARTS FOR
MERLIN 1000 SYSTEMS (continued)
NOTES
N2/CO2 speeds are typically 10% slower than air/air cuts. The quality of cut will be reduced on carbon steel with
N2/CO2 when compared to air/air cutting.
Poor parts life may result if exceeding the maximum recommended pierce thickness of 1/2 inch (12.7 mm).
