INTER-CONNECTION OF CONVERTERS
The input and electrode cables of the RED-D-ARC
MX350 Converters may be inter-connected in a RED-
D-ARC MX350 System using any combination of
Distribution Box(es) (see Figure 1), paralleling ( CC
mode only) and "daisy-chaining" (see Figure 2) which
best fits the field application setup within the capacity
of the power source supplying the system:
Power Source (Volts x Amp) capacity > 1.1 x Sum of
Convertersʼ (Volts x Amps) arcs
For Converters (operating at rated output) less than
200ft. (61m) from the power source, the following min-
imum cable sizes are recommended for the indicated
quantity of Converters supplied by the input cable run
to keep cable temperature and voltage drop within
acceptable limits:(See Table.1)

ELECTRIC SHOCK can kill.
Paralled units may be powered from
more than one source. Disconnect all
inputs, including outputs from other
sources before working on the equip-
ment. Before removing the parallel
jumper be sure both Converters are
switched OFF. If not, the male side of the first dis-
connection will be electrically "hot" to work.
