Connect Work Cable
Clamp the work cable to the workpiece or cutting table. The area must be free from oil, paint and
rust. Connect only to the main part of the workpiece; do not connect to the part to be cut off.
Power ON
Place the Power Supply ON / OFF switch to the ON (right) position. AC indicator
The Main Board performs several tests to determine the system is ready to operate. During the
self-tests the digital display first shows the firmware revision number which includes decimals.
1.1.0 is an example of a production released code revision that may be displayed.
If there are no issues detected the output current setting will be displayed from 15 to 40 amps.
Should a problem be detected the status code in letter format or Exx will display. Refer to Section
5 for fault / status code explanations.
The cooling fan will turn ON as soon as the unit is turned ON and will continue to run until the
power is turned OFF.
Set Operating Pressure
Gas pressure cannot be set at the power supply and must be set at the source, from 90 - 125 PSI
/ 6.2 - 8.6 bar / 620 - 862 Kpa.
NEVER EXCEED 150 PSI / 10.34 bar / 1034 Kpa.
Cutting Operation
Once the cutting arc is established, it should continue to cut until the trigger is released, the torch
is moved too far from the work piece or the duty cycle has been exceeded causing the system
to go into an over temperature mode. In the first two instances release the torch trigger, ensure
that the torch tip is close to the work piece, activate the trigger and reestablish the cutting arc.
In the event of an over temperature fault, release the trigger, allow the unit to run so it will cool
down. When the fault clears you can begin cutting again.
Typical Cutting Speeds
Cutting speeds vary according to torch output amperage, gas pressure, the type of material
being cut, and operator skill.
Output current setting or cutting speeds may be reduced to allow slower cutting when following
a line, or using a template or cutting guide while still producing cuts of excellent quality.
