TROUBLE
POSSIBLE CAUSE
REMEDY
____________________________________________________________________________________
Half cycle during weld
time.
NOTE: Ignitor Fuses
and resistors are
located on the
Ignitron/Firing
Module.
---------------------------
Weld too cool or too
small.
---------------------------
"HOT" Welds
I.
One ignitor circuit open.
II.
One ignitron tube or thyristor
does not conduct.
III.
Defective Terminal Strip/Firing
or Ignitron Firing Module PCB.
--------------------------------------------
I.
Line voltage drop.
II. Excessive pressure at elec-
trodes.
III.
Weld transformer set low.
IV.
Weld Count too short.
V.
Percent Current too low.
VI.
Electrode face too small.
VII.
Excessive tip "mushrooming".
--------------------------------------------
I.
Insufficient air pressure.
II.
Weld transformer set high.
III.
Weld Count set too high.
IV.
Percent Current set too high.
V.
Electrode diameter too small.
1.
Check connections to ignitor
resistor.
2.
Check ignitor lead connection to
tubes.
3.
Check for open ignitor fuse. (F4
and F5, BAF6).
1.
Check tube or thyristor for open.
Replace.
1.
Replace Board. See wiring
diagram for correct assembly
number.
--------------------------------------------
1.
KVA demand for welding
transformer too high for input
power line.
1. Check air supply.
1.
Increase transformer tap setting.
1.
Increase Weld Count duration.
1.
Increase value of Percent Current.
1.
Select correct electrode face
diameter.
1.
Properly dress tips.
--------------------------------------------
1.
Check air supply and accessories.
1.
Reset tap to lower setting.
1.
Reduce Weld Count duration.
1.
Decrease value of Percent
Current.
I.
Dress or replace tip with proper
size.
