CAUTION
The output voltage cannot be pre-
set.
1. Place the remote switch in
machine control. If normal oper-
ation is restored then the remote
control unit may be faulty.
Check or replace.
2. If an error message is displayed
see
Explanation of Error
Messages.

faulty. Replace.
The weld output terminals are
always electrically “hot”.
1. Remove any control cable that
may be connected to the 14 pin
amphenol. If the problem is
resolved the fault is in the con-
trol cable or the wire feeder.

present (over 3 VDC.) after per-
forming Step #1 then the prob-
lem is within the CV305.
