Cut expanded metal
Expanded metal has a slotted or mesh pattern. Cutting expanded metal causes cartridges to wear
more quickly because a continuous pilot arc is necessary. A pilot arc occurs when the torch is fired
but the plasma arc is not in contact with the workpiece.
Do these steps to cut expanded metal:
1. Install a Hypertherm cutting cartridge or FineCut cartridge.
2. Move the torch-lock switch to the green “ready to fire” ( )
position.
3. Push the button to move from Cut mode to Expanded Metal
mode.
Go back to automatic setting of the operating mode
When you manually set the operating mode, the plasma power supply keeps that setting
until you install a different type of Hypertherm cartridge or you install a different torch.
Do not set the operating mode when the torch-lock switch is in the yellow lock (X)
position. When you unlock the torch, the plasma power supply automatically sets the
operating mode to match the type of cartridge installed.
If you manually set the operating mode and then replace the Hypertherm cartridge with a
new cartridge of the same type, the plasma power supply keeps the operating mode that
you set.
The plasma power supply also keeps your setting if you do a quick restart or a cold
restart.
A type of Hypertherm cartridge refers to the amperage of the cartridge
and to its application, such as gouging, standard drag-cutting, FineCut, or
mechanized. Each type of Hypertherm cartridge has a different part
number.
