PROBLEMS

(SYMPTOMS)

POSSIBLE

CAUSE

RECOMMENDED

COURSE OF ACTION

Welder runs but fails to generate
current.

Welding arc is loud and spatters
excessively.

1. Generator or exciter brushes may

be loose or missing.

2. Exciter may not be operating.

3. Field circuit of generator or exciter

may be open.

4. Polarity reversing switch may be

in the neutral position.

5. Exciter may have lost excitation.

1. Series field circuit may be open

circuited.

2. Current setting may be too high.

3. Polarity may be wrong.

1. Be sure that all brushes bear on

the commutator and have proper
spring tension.

2. Check exciter output voltage with

voltmeter or lamp.

3. Check for open circuits in rheo-

stat, field leads and field coils.
Also check resistors.

4. Put handle in positive or negative

position.

5. Check components and continuity

in flashing circuit.

1. Check circuit with ringer or volt-

meter.

2. Check setting and current output

with ammeter.

3. Check polarity. Try reversing

polarity or try an electrode of the
opposite polarity.
