CUTMASTER 25mm
D. With CURRENT CONTROL
POTENTIOMETER set at maximum, output
current is only 60 amps.
1. Tip is touching the work piece, Drag mode.
a) Lift tip off work piece
2. Defective Pilot IGBT on Main PCB
a) Check per section 4.10.
E. In RAPID AUTO RESTART mode, with
torch switch closed, the pilot does not
start immediately when the cutting arc
extinguishes
1. Defective Logic PCB

5.11 CNC Interface Problems
A. Nothing happens when jumper is installed
between J2-3 to J2-4.
1. Defective Automation Interface PCB (PCB4)
a) Measure voltage on PCB4 between J1-6 to J1-8
for 12VDC.
If 12VDC is present replace PCB4
2. Defective Main PCB
a) Measure voltage on Main PCB between J1-6 to
J1-8 for less than 2VDC.
If voltage is less than 2VDC, replace PCB1
B. No OK-TO-MOVE signal while cutting.
1. Defective Main Pcb (PCB1)
a) Measure voltage on PCB4 between J1-1 to J1-3
for 12VDC while cutting.
If 12VDC is present, replace PCB1
2. Defective Automation Interface PCB (PCB4)
a) Measure voltage on PCB4 between J1-1 to J1-3
for less than 2VDC while cutting.
If voltage is less than 2VDC, replace PCB4.
C. ARC VOLTS signals are low or not present
1. Defective Automation Interface PCB (PCB4)
a) Replace PCB4
