5-2. Connecting Multiple Units
!
Turn Off welding power
source before opening ac-
cess door.
NOTICE − This procedure is not
for paralleling. Refer to connec-
tion below for paralleling pro-
cedures Severe damage to units
may occur if units are not correctly
connected for parallel operation.
To use two or more AC arcs with
separate electrodes, make con-
nections as shown.
Set up AC output units according to
Section 5-3.

NOTICE − If there are any ques-
tions regarding the paralleling pro-
cedure, contact the factory before
connecting units. Severe damage
to units may occur if units are not
correctly connected for parallel
operation.
To use two or more units with one
electrode, make connections as
shown.
Set up AC output units according to
Section 5-3.
.
The first unit controls voltage.
All remaining units supply addi-
tional current.
1 Power/Balance Control
NOTICE − All units being paralleled
must be set to the same balance
(see Section 6).
2 CC/CV Switch
NOTICE − All units being paralleled
must be in CC position (see Section
6).
.
When running multiple units in
parallel, Parallel Controller
(Miller part number 194711)
must also be used. Install con-
troller according to instructions
provided with unit.
.
Although all units are set in the
CC position, the paralleled pro-
cess runs in constant voltage.
