5.01 Basic Troubleshooting-Power Source Faults
In the table below, words "Faulty Power PCB, Control PCB or Display PCB" will appear, refer to relative
sections to detect and confirm the fault.
Refer to Section 5.06, 5.08, 5.09 and 5.10/Item 1/Power PCB to detect whether the Power PCB is defective.
Refer to Section 5.07, 5.10/Item 4/Control PCB and 5.11 to detect whether the Control PCB is defective.
Refer to Section 5.10/Item 3/ Display PCB to detect whether the Display PCB is defective..
If Power PCB, Control PCB or Display PCB is broken, replace accordingly.

TROUBLESHOOTING
NOTE
Possible Cause
A
The main Power Switch is set to OFF
B
Line fuse is blown
C
The main Power Switch is faulty
D
Loose connection
E
Faulty Power PCB
Faulty Control PCB
F
Faulty Display PCB
G
A The internal protection circuit to
shut the unit down if the mains
supply voltage is too high has
operated
A
Unit has overheated
B
Airflow inlet or outlet ducts are
blocked
C
Fan does not operate
A Faulty Display PCB
A
Internal wiring fault
B
Over temperature light is on
C
Power Source set to REMOTE
D
Trigger wires shorted to weld
voltage inside torch

FABRICATOR 211i
Remedy
A
Set main Power Switch to ON
B
Replace Line fuse
C
Replace main Power Switch
D
Tighten connections
E
Replace Power PCB
F
Replace Control PCB
G
Replace Display PCB
A
Check to see if mains supply
voltage is <274VAC. A
generator with poor voltage
regulation may cause a supply
voltage in excess of 274VAC.
Connect Power Source to a
supply voltage <274VAC.
A
Allow unit to cool with fan
running until over temperature
light extinguishes
B
Remove blockages from airflow
ducts
C
Replace fan. Check fan wiring
header is plugged securely into
Control PCB. Check fan wiring
for damage.
A
Replace Display PCB
A
Check continuity of internal
wiring from Torch adaptor
through to boards
B
Allow unit to cool
C
Set switch to LOCAL
D
Repair trigger wires in torch
E
Check & Repair
F
Replace Power PCB
G
Replace Control PCB
H
Replace Display PCB
