SECTION  5

TROUBLESHOOTING

The cause of control malfunctions can be found by
referring to the sequence of operations and electrical
schematic diagram and checking  the various com-
ponents.  A volt-ohmmeter will be necessary for
some of these checks.

Voltages in plasma cutting equipment are high enough
to cause serious injury or possibly death. Be particu-
larly careful around equipment when the covers are
removed.

NOTE

Before checking voltages in the circuit, disconnect the
power from the high frequency generator to avoid damag-
ing your voltmeter.

5.1  TROUBLESHOOTING

ELECTRIC SHOCK CAN KILL! Be sure that all primary
power to the machine has been externally discon-
nected. Open the line (wall) disconnect switch or
circuit breaker before attempting inspection or work
inside of the power source.

Check the problem against the symptoms in the following
troubleshooting guide.  The remedy may be quite simple.
If the cause cannot be quickly located, shut off the input
power, open up the unit, and perform a simple visual
inspection of all the components and wiring.  Check for
secure terminal connections, loose or burned wiring or
components, bulged or leaking capacitors, or any other
sign of damage or discoloration.

Depress torch switch.  After 2 seconds, is high frequency present?

No
