COURSE OF ACTION
The MIG PULSER does not give a
satisfactory Weld.
The voltmeter on the wire feeder (if
equipped) will not display.
1. Incorrect settings at the V300.
Make sure the V300 switches are
set in the proper positions. See
V300 SETTINGS in the
Operation section of this manual.
2. Output Cables are either too long
or of improper size. See OUT-
PUT CABLES FOR PULSE
WELDING in the Installation sec-
tion of this manual.
3. The control cable may be extend-
ed too long. Do not use more
than one optional 25 foot control
cable extension.
4. There may be high frequency
interference. Refer to the HIGH
FREQUENCY INTERFERENCE
PROTECTION section in the
Installation section of this manual
for proper installation guidelines.
1. This is normal. The wire feeder
voltmeter will not display since
there is no 21 lead in the feeder
connection.
