ULTRA-CUT 400
3. Turn on 3 phase power at the main disconnect (Plasma Enable on TSC 3000 Disabled).
a) AC indicator on front panel does not come on, pump and fans do not start.
b) Approximately 10 sec after power up the front panel DC indicator will blink twice indicating this is an
Ultracut.
c) Immediately following this the Temp, Gas, DC & Status indicators will blink the CCM firmware version.
Example, version 4.1 will blink 4 times followed by a short space then blink once more.
d) At the same time the DMC & DPC, both Green & Red LEDs, also blink their firmware version in the same
fashion.
e) After blinking the CCM firmware version on the front panel indicators the CCM establishes communica-
tion with the DMC & DPC. Once communication is established the Green LEDs are on steady and the
Red LEDs should be off.
4. At power on while all the items in step 2 (or 3) are going on the TSC 3000 has been starting up Windows XP™
which takes about 2 ¼ minutes. Another 15 sec the application starts and displays the HOME screen.
5. Now you must select the cutting (and plasma marking) process. Refer to sections 4.05, 4.06 and 4.07 for step by
step instructions in selecting New, Recently Used or Creating Custom Processes.
6. During process selection you will come to the “Torch Consumables” screen. At this point if you have not installed
correct consumables and “Plasma” is not already disabled, shut off (disable) the Plasma Enable SW. Install the
consumables, Set the Plasma Enable SW to “Enable”.
a) Coolant Pump and fan start up to prime the torch cooling system. The “Gas” indicator on the front panel
blinks until correct coolant flow is detected. Normally only a few seconds. See step 2.d. for full details.
7. The next screen following Torch Consumables is a table of recommended CNC and THC (Torch Height Control)
settings. You may toggle between cutting and marking settings using the “Show Marking / Show Cutting” but-
ton. Set your cutting table controller and height control to the recommended setting.
a) If you prefer other settings for cutting you can create a “Custom” process where you edit the cutting
CNC/THC setting if you want. Currently, modifying the marking CNC/THC settings is not allowed.
A custom process does not have to change the cutting current or gas pressures unless you want to. You
can use customs to modify the recommended CNC/THC settings as well.
8. Continue the process selection until you reach the Cut Monitor screen.
a) Purging of the gasses used for the selected process begins. Depending on your lead length and consum-
able type this can take some time.
Purge times for different lead lengths have been set to allow time to fully pressurize the leads and to remove
any coolant that gets into the consumables during a parts change. Make sure that during setup the correct lead
length has been selected, the default time is for max lead length and may be longer than you require.
9. Once purge is complete you are ready to start cutting.
a) If marking is desired press button “Go to Marking”. The screen will show recommended CNC/THC
setting. Green arrow takes you back to the Cut Monitor set up for Marking.
b) To return to cutting on the Cut Monitor press button “Got to Cutting”. Same as with the marking this
takes you to the CNC/THC screen except this displays the cutting settings.
10. Changing torch consumables:
Following a consumables change or inspection the system will initiate a purge of the gas. This serves two purposes:
a) Remove the coolant that gets into the consumables when they have been removed.
b) If the gas type has changed “Purge” removes the old gas from the lines and replaces it with the new
gas. If the gas type has changed from a fuel gas like H35 to an oxidizing gas like oxygen or air the purge
inserts a buffer of inert gas, nitrogen, so the H35 and oxygen don’t mix.
