Gouging problems
When gouging, always make sure of the following:
 A Hypertherm gouging cartridge is installed.
 The Hypertherm cartridge is not worn or damaged. Refer to Signs that a cartridge is near
end-of-life on page 74.
 The operating mode is set to Gouge mode.
The torch does not cut fully
through the workpiece.
• Examine the Hypertherm cartridge. Replace it if it is worn or damaged.
Refer to Signs that a cartridge is near end-of-life on page 74 and Cartridge
maintenance on page 118.
• Decrease your cut speed.
• Make sure that the torch is being used correctly. Refer to Cut and Mark with
the Hand Torch on page 63.
• Increase the output current (A) on the plasma power supply. Refer to
page 58.
• If the output current (A) cannot be increased, make sure that the thickness
of the metal being cut is less than the maximum capacity for the plasma
power supply. Refer to Cutting specifications on page 25.
• Clean the area where the work clamp touches the workpiece. Remove any
rust, paint, or other material. Make sure that there is good metal-to-metal
contact.
• Examine the torch lead. Make it straight if it is twisted or kinked. Replace it if
it is damaged.
• Examine the gas pressure and the gas supply hose. Refer to page 91.
• Adjust the gas flow rate.
