TROUBLESHOOTING
PROBLEMS
(SYMPTOMS)
Major Physical or Electrical
Damage is Evident
There is no wire feed or open cir-
cuit voltage when the gun trigger is
pulled. Input power is applied to
POWER MIG 215.
Output voltage and wire feed is pre-
sent when gun trigger is not pulled
(not activated).
Machine output is low. Welds are
“cold”, weld bead is rounded or
bumped up demonstrating poor
wetting into plate.
POSSIBLE
CAUSE
1. Contact your Local Lincoln
Authorized Field Service Facility.
1 The gun trigger or cable may be
faulty. Check or replace gun
assembly.
2. The thermal protection circuit
may be activated. If this is the
case allowing the machine to
cool will clear the error condition.
3. Make sure input voltage is cor-
rect and matches nameplate rat-
ing and reconnect panel configu-
ration.
4. If spool gun option kit is in
stalled, check to see that it is set
to “Normal” if pulling the gun trig-
ger associated with built in feed-
er, and “Spool Gun” if pulling
spool gun trigger.
1. Remove gun assembly from
machine. If problem is solved
gun assembly is faulty. Repair or
replace.
2. If problem persists when gun
assembly is removed from
machine then the problem is
within the POWER MIG 215.
1. Check input voltage. Make sure
input voltage matches name-
plate rating and reconnect panel
configuration.
2. Make sure settings for wire feed
speed and voltage are correct
for process being used.
3. Make sure output polarity is cor-
rect for process being used.
4. Check welding cables and gun
assembly for loose or faulty con-
nections.
RECOMMENDED
COURSE OF ACTION
If all recommended possible areas
of misadjustment have been
checked and the problem persists,
Contact your local Lincoln
Authorized Field Service Facility.
OUTPUT PROBLEMS
