Observe Safety Guidelines

TROUBLESHOOTING GUIDE

detailed in the beginning of this manual.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the test/repairs safely, con-
tact the Lincoln Electric Service Department for electrical troubleshooting assistance before you proceed. Call
1-800-833-9353.

PROBLEMS
(SYMPTOMS)

POSSIBLE AREAS OF
MISADJUSTMENT(S)

RECOMMENDED
COURSE OF ACTION

OUTPUT PROBLEMS

Major physical or electrical dam-
age is evident when the sheet
metal cover(s) are removed.

1. Contact your local authorized

Lincoln Electric Field Service
Facility for technical assistance.

1. Contact the Lincoln Electric

Service Department,

1-800-833-9353 (WELD).

Machine is dead – no output – no
fan – no status indicator lights.

1. Make sure that the input power

switch is in the “ON” position.

2. Check the input voltage at the

machine. Input voltage must
match the rating plate and the
reconnect panel.

3. Check for blown or missing

fuses in the input lines and the
0.6 amp slow blow reconnect
fuse.

1. Check the input power switch

(S1) for proper operation. See
the Wiring Diagram.

2. Check the leads associated

with the power switch (S1) and
the auxiliary transformer (T2) for
loose or faulty connections.
See the Wiring Diagram.

3. Perform the

Auxiliary Trans-

former Test.

Machine is dead - not output - no
status indicator lights - fans run.

1. Check the input voltage at the

machine. Input voltage must
match the rating plate and the
reconnect panel.

1. Perform the

Auxiliary

Transformer Test.

2. Perform the

Low Voltage

Circuit Test.

3. Perform the

Input Rectifier

Test.

4. The control board may be

faulty. Replace.

5. The display board may be

faulty. Replace.

All status indicators remain lit
immediately after power up.

1. The microprocessor has experi-

enced a memory fault. Contact
your Local Lincoln Authorized
Field Service Facility.

1. The control board may be

faulty. Replace.
