FIGURE E.2 – INPUT LINE VOLTAGE
GENERAL DESCRIPTION
The PRO-CUT 25 is an inverter based constant
current, continuous control plasma cutting power
source. The control system has a safety mechanism
to insure that the nozzle and electrode are in place
before cutting or gouging. The PRO-CUT 25 initiates
the plasma arc with a simple, yet reliable, touch start
mechanism. This system eliminates many of the prob-
lems associated with hi-frequency type start systems.
INPUT LINE VOLTAGE, AND
AUXILIARY TRANSFORMER
The single-phase input power of 115 230 Volts AC is
connected to the machine, via an input cord, to a
switch located on the front panel.
The PRO-CUT 25 Input voltage board automatically
reconnects the auxiliary and inverter connections to
configure the machine for either a low 115V AC or high
230V AC input voltage. The auxiliary transformer
develops the appropriate AC voltages to operate the
cooling fan, the control board, and the inverter board.
