ULTRA-CUT 200 XT
A-94 APPENDIX Manual 0-5304
Torch Parts Selection
The output of the power supply is fixed at 100 Amps. Torch is assembled with 100 Amp parts from the factory.
Refer to the SL100 torch manual for details.
Drag cutting with 1Torch.
For best consumable life, drag cutting should use the special Drag Shield Cap or the Shield Cup Standoff guide
which does not allow tip to work contact, and allows cutting with the full 100A
With the standard standoff 100A tip, if it comes in contact with the work the current is reduced to 40A to prevent
damage to the tip. You may drag cut this way at the reduced current but tip life may be somewhat reduced.
With the standoff tip you must trigger the 1Torch with the tip above the work to start the preflow or you will get
a 701 fault. Once in preflow the tip may be brought into contact with the work for cutting at reduced current.
Parts - In - Place (PIP)
The torch includes a ‘Parts - In - Place’ (PIP) circuit. When the shield cup is properly installed, it closes a switch.
The torch will not operate if this switch is open.

Preflow
After the torch trigger is pulled, the air will flow for 2 seconds. This allows possible contamination to be elimi-
nated from the torch before the arc is established.
Postflow
After the torch trigger is released the arc will stop and the air will flow for 20 seconds. This allows the operator
to safely switch modes at the XT power supply which will not allow the automated cutting to occur.
Pilot Arc
When the torch leaves the workpiece the pilot arc restarts instantly, and the cutting arc restarts instantly when
the pilot arc contacts the workpiece.
Foldback Feature
The unit will automatically drop the cutting current down to 45 amps if the exposed tip touches the plate while
cutting. This will dramatically improve tip parts life.
