Solution
The cut quality is
unsatisfactory.
• Examine the Hypertherm cartridge. Replace it if it is worn or damaged. A
higher rate of 0-30-0 faults is typical as a cartridge gets near end-of-life.
Refer to
Signs that a cartridge is near end-of-life
• 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
on page 95. For a machine torch, refer to the
Powermax65/85/105 SYNC Mechanized Cutting Guide
(810480).
• Examine the gas pressure and the gas supply hose. Refer to
.
• Examine the gas filtration system for signs of contaminants that are possibly
causing interference with plasma power supply performance. Refer to
• 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
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
.
The LCD screen on the
front panel is too bright or
too dark.
• Very hot environments can make the LCD screen darker. Very cold
environments can make the LCD screen brighter. Adjust the brightness and
contrast settings as necessary on the LCD Display screen (
LCD DISPLAY
).
.
The cartridge end-of-life
detection feature is on, but
it is not working.
The plasma power supply temporarily disables the Hypertherm cartridge
end-of-life detection feature when one of the following conditions occurs, even
when the feature is on:
• You install a FineCut hand cutting cartridge.
• You set the output current below 40 A for any type of Hypertherm cartridge.
The cartridge end-of-life detection feature is different when the system is in
basic mode. Refer to
for more information.
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:
• Install a different type of cartridge.
• Adjust the gas pressure while the torch is locked and then 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
