Type of metal:
1
• Mild Steel
• Stainless Steel
• Aluminum
Cut process:
• A = Amperage. The amperage applies to all the settings on that page.
• In FineCut charts, the amperage for each thickness is included in the cut chart.
This guide includes high-speed and low-speed charts. High-speed settings can
give better cut quality and less dross at some thicknesses, if the cutting table lets
you cut at those settings.
Type of gas:
• Air (or nitrogen)
• F5
Use an ohmic sensing ring to connect a mechanized cartridge
to a torch height control (THC) system. Install it on the cartridge
as shown. The 428895 kit includes 3 ohmic sensing rings

finish). Adjust the speed for your application and cutting system to get the
desired result.

Differences between installations and material composition can cause actual
results to vary from those shown in the tables.
Units of measurement:
3
• mm = millimeters
• % = percentage
• seconds
• mm/min = millimeters per minute
• volts
• inches
• in/min = inches per minute
• A = amperage (FineCut charts)
Edge start = Start the cut from the edge of the workpiece.
Each cut chart lists hot and cold gas flow rates.
4
• slpm = Standard liter per minute
• scfh = Standard cubic feet per hour
Hot (cutflow) = Plasma arc is on, and there is a steady flow of
gas while cutting.
Cold (postflow) = Plasma arc is off, and there is a steady flow
of gas for several seconds after the cut completes. This
flow rate also applies for gas test mode.
