Connecting 120 VAC Power
Installation must meet all National and Local
Codes. This installation must be
electrically con-
nected
by a Suitably Trained and Qualified
Tradesperson.
DO NOT TOUCH
any
live electrical parts or conductors.
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and
work circuit is electrically live whenever the
output is on.
DO NOT WORK ALONE! The Input Power
Supply circuit and Power Source internal cir-
cuits are also live when power is on.
NOTE
4:
These Products configures the Power Source
to the operating parameters for 120 / 208 / 230 / 240
VAC.
Electrical Input Requirements
Operate the Power Source from a single-phase, 50/60
Hz, AC Power Supply
available on SITE
. The
Input
Supply Voltage
must match one of the electrical input
voltages shown in this manual.
Refer to Figure 1 and
Table 1
for connection, maxi-
mum Input Supply Voltage and Fuse Size.

NOTE
5
:
The time-delay fuse or circuit breaker of an
individual branch circuit may have nuisance tripping
when welding with this Power Source due to the am-
perage rating of the time-delay fuse or circuit breaker.
The recommended time delay fuse or circuit breaker
size
for welding is shown in
Table 1
(with Input Supply
Voltage = 120 VAC)
and an individual branch circuit is
recommended for this application. Fuse/Circuit Breaker
size is based on not more than 200% of the rated input
amperage of the Power Source. Refer to National Elec-
trical Code Article 630.12.
Use the
Power Adapter (
2
and
3
) to connect the Power Source Input Power Cord Plug (1) to the Receptacle Outlet (
4
).
