Tweco 300 XT Ultra-Cut Plasma Cutting System With Automated Gas Control - Manual (Page 74)

ULTRA-CUT 300 XT
�-2 OPERATION Manual 0-5305
NOTE
Prior to starting the system determine the process to be used. The process is determined by the type
and thickness of the metal to be cut. Select and install the required consumables, connect the required
gasses to the system.
1. Connect system to primary input power. An indicator will light on the rear panel when AC power is ap-
plied to the unit. Place the Plasma Enable Switch (TSC 3000; user installed Plasma Enable/E-Stop) in the
“Enable” position
2. Turn ON/OFF switch to ON (up) position. System goes through the “Start up Sequence”.
• For about 10 seconds the decimal points of the 4 digit display blink from right to left.
• Next the 4 rectangular LED indicators and the 4 status display digits illuminate all segments as a test.
• Then for about 6 seconds the display shows the letter “C” (code) followed by the CCM code version.
Example “C1.2.0” . During this time various input voltage tests are being performed. If a fault is found
its code is displayed and the start up sequence halts. Faults will show “E” or “L”. If Plasma hasn’t been
Enabled by this point, E101 will be displayed and the startup sequence will not proceed.
• The coolant pump starts, the Gas LED indicator blinks and the display shows “0” indicating no cutting
process has been loaded.
o If the unit is disabled, Plasma Enable shut off, the pump doesn’t start and display alternates between
status code E101 and “0”.
• Assuming the unit is not disabled, as soon as adequate coolant flow is detected, usually in about 5 seconds,
the Gas LED stops blinking and the contactors close and the AC LED Indicator lights.
o If there are bubbles in the coolant code E�0� may be displayed alternating with “0” until the bubbles clear
up. This is a warning and you can continue.
o If flow is not detected, the pump will run and the Gas LED blinks blinks until flow is detected or for up
to � minutes at which time the pump stops and the display shows E�0� indicating proper coolant flow
was not obtained.
• Now select and load the cutting process using the TSC 3000 or the program included in the CNC control.
Once the process is loaded a gas purge begins. Purge time varies with the torch lead length and the cut-
ting process. See section �.03 to �.0� for details of using the TSC 3000 or the CNC manual for embedded
programs. Also refer to section �.09 for a more detailed Sequence of Operation.
• During the gas purge the Gas LED will blink and the display will show E304 alternating with the cutting
current indicating a gas purge is in progress. E30� goes away and the Gas LED stops blinking at the end
of the gas purge. A purge is also initiated, with E30� and blinking Gas LED, when the unit is enabled
following a disable. Does not require loading the process again.
