INSTALLATION
Location
For best operating characteristics and longest unit
life, take care in selecting an installation site. Avoid
locations exposed to high humidity, dust, high am-
bient temperature, or corrosive fumes. Moisture can
condense on electrical components, causing corro-
sion or shorting of circuits. Dirt on components helps
retain this moisture.
Adequate air circulation is needed at all times in
order to assure proper operation. Provide a mini-
mum of 12 inches (305 mm) of free air space on all
sides of the unit. Make sure that the ventilator
openings are not obstructed. Ventilation air flow is
from rear to front.
Voltage Configuration
(See Figure 4-1)
For proper operation the machine must be config-
ured for the correct line voltage. The voltage selec-
tion switch is located on the rear panel of the power
source next to the main power ON/OFF switch. For
operation on either 200 or 230VAC slide the switch
upwards to the 200/230V setting, for operation on
either 400 or 460VAC slide the switch down to the
400/460V setting
CAUTION: Make sure the main power
switch is in the OFF position before
making any changes to the voltage se-
lect switch. This switch should not be
switched with load on the machine.
Connecting The Welding
Machine To Line Voltage
The input power should be connected to the ma-
chine through a fused disconnect switch or other
suitable disconnecting means furnished by the
user. Table 4-1 provides minimal information for
selecting line fuses.
A four conductor power cable (6/4) is provided with
the machine for connection to the AC power source.
It is the responsibility of the user to provide the
proper plug or other means of connection to the
cable.
