Hand gouging problems
When gouging, always make sure of the following:
A Hypertherm gouging cartridge is installed.
The Hypertherm cartridge is not worn or damaged.
The operating mode is set to Gouge mode.
When you install a Hypertherm gouging cartridge, the plasma power supply
automatically sets the operating mode to Gouge mode. There is a condition in which the
operating mode does not automatically set to Gouge mode even if a Hypertherm
gouging cartridge is used.
The fault LED on the hand
torch flashes yellow, but no
fault code or fault icon
shows on the
status
screen.
• The fault LED on the hand torch flashes yellow when the system is in basic
mode. When you go back to smart mode, the fault LED on the torch
changes to green. Refer to Smart mode versus basic mode on page 155.
