DISCHARGE PROCEDURE
The machine has internal capacitors which are
charged to a high voltage during power-on
conditions. This voltage is dangerous and must
be discharged before the machine can be
serviced. Discharging is done automatically by
the machine each time the power is switched off.
However, you must allow the machine to sit for
at least 5 minutes to allow time for the process
to take place.
To avoid receiving a high frequency shock, keep
the TIG torch and cables in good condition.
