TROUBLESHOOTING GUIDE
PROBLEMS
(SYMPTOMS)
Machine shuts off (input contactor
drops out) when the welder output
terminals are made electrically
"hot".
(#2 to #4 closure at terminal strip.)
The DC600 will NOT shut off when
the Stop button is pushed.
POSSIBLE AREAS OF
MISADJUSTMENT(S)
1. Remove all welding cables and
control cables from the DC
600. Jumper #2 to #4 at the
terminal strip. If the machine
does NOT shut off and normal
open circuit voltage is present
at the welder output terminals
the problem is external to the
DC600. Either the remote
leads #75, #76 or #77 are
grounded to the negative out-
put cable or there is a short on
the welding output terminals.
2. If the machine still shuts off
when all control and welding
cables are removed then the
problem is internal to the
DC600.
1. Contact your local Lincoln
Authorized Field Ser vice
