INTER-CONNECTION OF CONVERTERS
The input and electrode cables of the Multi-Weld 350
Converters may be inter-connected in a Multi-Weld
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 mini-
mum cable sizes are recommended for the indicated
quantity of Converters supplied by the input cable run to
keep cable temperature and voltage drop within accept-
able 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 equipment. Before
removing the parallel jumper be sure both
Converters are switched OFF. If not, the male
side of the first disconnection will be electri-
cally "hot" to work.
