HIGH VOLTAGE TRANSFORMER AND CIRCUIT TEST
TEST PROCEDURE
NOTE: This test can be performed best
with alligator clips used with the meter
probes.
NOTE: This test requires that the torch
trigger be pulled to activate the circuit. Be
sure to use an isolated meter because of
the high voltage and high frequency pro-
duced.
1. Connect input power to the machine.
2. Turn ON/OFF Power Switch to OFF.
Test A: Test for 115 VAC primary
voltage to High Frequency
Transformer
1. Locate and connect probes to leads
#35 and #31 on Control Relay CR2.
Use alligator clips for best results.
See Figure F.12.
2. Turn ON/OFF Power Switch to ON.
3. Pull the torch trigger to close Control
Relay CR2 contacts. 115 VAC will
be present for only ONE SECOND
when the torch trigger is pulled.
NOTE: When using an analog meter, the
pointer will deflect to approximately 20
VAC. This is normal.
4. Turn ON/OFF Power Switch to OFF.
a. If the 115 VAC primary voltage is
not present, Control Relay CR2
or the Control Board could be
faulty. Replace.
