EX350i
PARALLEL OPERATION
The EX350i are operable in parallel in CC mode. For
best results, the currents of each machine should be
reasonably well shared. As an example, with two
machines set up in parallel for a 400 amp procedure,
each machine should be set to deliver approximately
200 amps, not 300 amps from one and 100 amps
from the other. This will minimize nuisance shutdown
conditions. In general, more than two machines in
parallel will not be effective due to the voltage require-
ments of procedures in that power range.
To set machine outputs, start with output control pots
and arc control pots in identical positions. Use the
output control pots to balance the currents and main-
tain the desired voltage or current. The arc control
pots should be kept identical on the two machines.
