Observe all Safety Guidelines detailed throughout this manual

OUTPUT PROBLEMS

PROBLEMS

(SYMPTOMS)

POSSIBLE 

CAUSE

RECOMMENDED

COURSE OF ACTION

The machine will not produce more

than 200 amps.

1. This may be normal operation.  If

the  output  current  exceeds  300

amps,  an  electronic  protection

circuit  will  reduce  the  current  to

less  than  200  amps.    The

machine will continue to produce

this  low  current  until  the

protection  circuit  is  reset.    Reset

occurs  when  the  output  load  is

removed.

2. Check the input voltage and input

voltage  reconnect  procedures.

See 

Input Voltage Reconnect

Procedure

.

3. Check for loose or faulty welding

cables.

If  all  recommended  possible  areas  of

misadjustment  have    been  checked

and  the  problem  persists, 

Contact

your local Lincoln Authorized Field

Service Facility.

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, con-

tact your local authorized field service facility for technical troubleshooting assistance before you proceed.
