Problem Solution
The cut quality is
unsatisfactory.
• 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.
• Make sure that the work lead connection to the plasma power supply is
tight. Make sure that there is no damage to the work lead.
• Make sure that the torch is being used correctly. Refer to About the hand
torch on page 64.
• Examine the gas pressure and the gas supply hose. Refer to page 91.
• Examine the gas filtration system for signs of contaminants that are possibly
causing interference with plasma power supply performance. Refer to
page 92.
• Adjust the cut speed.
• Operate the plasma power supply without using an extension cord. If you
must use an extension cord, use a heavy conductor cord of the shortest
possible length. Refer to page 36.
The ON / OFF power
switch is set to ON (I), but
the power ON LED ( )
is off.
• Make sure that the power cord is connected correctly to the power outlet or
line-disconnect switch box.
• Make sure that the power is on at the main power panel or at the
line-disconnect switch box.
• Make sure that the circuit breaker did not open (trip).
• Make sure that the line voltage is not too low (more than 15% below the
rated voltage). Refer to page 31.
The system changes the
gas pressure after I set it
manually.
The following conditions cause the system to override a manual gas pressure
setting with the default gas pressure setting that matches the type of cartridge
installed on the torch:
• You install a different type of cartridge.
• You adjust the gas pressure while the torch is locked and then you unlock
the torch.
Go back to manual gas pressure mode, and set the gas pressure again. Make
sure that the torch is unlocked before you set the gas pressure. Refer to
page 52.
The system changes the
output current (A).
• Set the torch-lock switch to the “ready to fire” ( ) position before you
adjust the amperage. The system does not keep the amperage setting while
the torch-lock switch is in the yellow lock (X) position. When you set the
torch-lock switch to the “ready to fire” ( ) position, the system
automatically sets the amperage.
