service technician.
ELECTRIC SHOCK CAN KILL! Be sure that all primary power to the machine has
been externally disconnected.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.
Those indications do not invalidate all other safety regulations and restrictions expressed in other sections
of this manual.
Voltages in plasma cutting equipment are high enough to cause serious injury or possibly death.
