ULTRA-CUT 200 XT
Manual 0-5304 APPENDIX A-49
Ultra-Cut XTs have standard consumables for cutting currents lower than those used for Auto-Cut XT, 15A vs. 55A
as well as marking at lower currents. To improve operation at these lower currents an additional output inductor,
L1, is added in series with the 1st inverter section (IM#1A).
Optional 1Torch module
Starting early in 2015 all the Auto-Cut 300 XT and Ultra-Cut XT models may be ordered from the factory with an
optional module allowing connecting an SL100 “1Torch” that cuts at a fixed 100A. The module is built into the XT
supply front panel just above the coolant tank filler cover. Connect a shop air supply and an SL100 torch and you
can use this torch with its relatively low cost consumables to hand cut scrap or whatever you wish without wearing
the higher cost consumables of the XT torch.
Status codes.
The codes for the power supply are displayed on the Display PCB 4 digit numerical display. Some codes refer to
the Gas Controls but more detailed Gas Control codes will be found on the individual gas controls. The gas con-
trols used with the XT family of plasma supplies have not changed. They have their own set of status codes which
should be covered in another section. This guide assumes you have first considered the Status Code Tables in the
Operation Section of the unit manual. Individual codes will point to different inverter sections while this guide
groups similar codes together. For example code E (or L) 249 indicates an inverter fault in Inverter 2A. This guide
covers codes 247-252 in one section as they are all the same, varying only by which inverter and section they refer to.
The codes are separated into 7 groups.
Group 1 Plasma Process -- Relating to pilot, transfer, torch voltages, etc.
Group 2 Plasma Power Supply -- Primarily the Inverter Sections
Group 3 Interface to Gas controls -- Mainly the DFC 3000
Group 4 Cooling System -- The liquid cooling system for the torch and inverters
Group 5 CCM -- Communications port to the gas controls
Group 6 CCM -- Status
Group 7 Accessories – 1Torch
For the XT units we are using a 3 digit code with group 1 codes in the 100’s, group 2 in the 200s etc. These cor-
respond to the older codes used in previous units, where 1-1 is now 101. For the most part the codes have the
same meaning. Where an older code no longer applies to the XT system we don’t use it over again and have left it
reserved to avoid confusion. For example the code 204 (2-4) which meant the inverter module wasn’t ready. We
now detect that error in a different way that has a somewhat different meaning so we have reserved the 204 Code.
While most of the codes indicate a fault has occurred, a few of them, such as 304 (formerly 3-4), simply refer to
the current status. 304 indicates either “priming” where the pump is filling the system with coolant or more often
“purging” where the gas is flowing to dry the consumables after replacing them or purging the gas lines when a
different gas type has been selected.
