PROBLEMS

(SYMPTOMS)

POSSIBLE

CAUSE

RECOMMENDED

COURSE OF ACTION

Input fuses keep blowing

Machine will not power up (no lights)

Machine won’t weld, can’t get any output.

This problem will normally be accompa-
nied by an error code. See “Status Light”
section of this document for additional
information.

1. Improperly sized input fuses.

2. Improper Weld Procedure requiring out-

put levels in excess of machine rating.

3. Major physical or electrical damage is

evident when the covers are removed.

1. No Input Power

2. Input voltage is too low or too high.

1. Input voltage is too low or too high.

2. Thermal Error.

3. Secondary current limit has been

exceeded. (see error 54)

3a. Input control board fault (see input

control board error status).

1. Make sure fuses are properly sized. See

installation section of this manual for
recommended sizes.

2. Reduce output current, duty cycle, or

both.

3. Contact your local authorized Lincoln

Electric Field Service facility for techni-
cal assistance.

1. Make sure input supply disconnect has

been  turned  ON.  Check  input  fuses.
Make  certain  that  the  Power  Switch
(SW1)  on  the  power  source  is  in  the
“ON” position.

2. Make certain that input voltage is cor-

rect, according to the Rating Plate locat-
ed on the rear of the machine.

1. Make certain that input voltage is cor-

rect, according to the Rating Plate locat-
ed on the rear of the machine.

2. See “Thermal LED is ON” section.

3. Possible short in output circuit. If con-

dition persists, contact an authorized
Lincoln Electric Field Service facility.
