SECTION 4 – INSTALLATION
4.1
Environment
This Power Source is designed with an Ingress Pro-
tection (IP) Rating of IP23S and is suitable for:
a)
Welding Indoors when the area is adequately ven-
tilated to remove welding fumes away from user.
b)
Weld Outdoors ONLY when it is NOT RAINING
.
c)
An environment where –
The risk of an electric shock or electrocution by arc
welding is low;
Normal work practices are used; and
It is not possible for a welder or any other workers
to be in contact with the workpiece, in the event of
coming into contact with a “hot” welding circuit.
DANGER
– DO NOT weld in rain or in water or
near water or leave the Power Source outdoors
while it is raining.
4.2
Location
Be sure to locate the Power Source according to the
following guidelines:
In areas free from oil, steam, corrosive gases moisture,
standing water and dust.
In areas with ambient temperatures between 32° F to
104° F (0°C to 40° C).
In areas not subjected to abnormal vibration or shock.
In areas not exposed to direct rain or sunlight.
Place at a distance of 12 in. (300mm) or more from
walls or similar that could restrict natural air flow for
cooling.

Explanation of Supply Voltages
208 VAC, 220 VAC, 230 VAC and 240 VAC are often used inter-
changeably for commonly available higher powered electrical prod-
ucts. 110 VAC, 115 VAC and 120 VAC are often used interchangea-
bly for commonly available lower powered electrical products.
However, the use of these various voltage terminologies is largely
inaccurate.
110/115 VAC: Are outdated and typically no longer supplied by
utilities. 120 VAC replaces 110/115 VAC.
120 VAC: 120 Volts AC is the common low voltage
supplied by US / Canadian utilities. See Sec-
tion 3.9 or 3.10 regarding usage at this volt-
age.
208 VAC: 208 Volts AC is a specific voltage supplied to
commercial facilities. See Section 3.9 or 3.10
regarding usage at this voltage.
230 VAC:
Is outdated and typically no longer supplied by utili-
ties. 240 VAC replaces 230 VAC.
240 VAC: 240 Volts AC is a specific voltage supplied to
commercial facilities. See Section 3.9 or 3.10
regarding usage at this voltage.

Electrical Input Power Guide
Failure to follow these electrical input power
guide recommendations could create an
electric shock or fire hazard. These recom-
mendations are for a dedicated circuit sized
for the rated output and duty cycle of the
power source.
In dedicated circuit installations, the
National Electrical
Code allows the receptacle outlet or conductor rating to be
less than the rating of the circuit protection device. See NEC
articles 210.21, 630.11 and 630.12.
NOTE 2:
Actual input voltage should not exceed ± 10% of
indicated required input voltage.

Extension Cord Recommendations
DANGER – Never use an extension cord outdoors that is
not marked for outdoors use. Make sure equipment is OFF
before connecting extension cord to outlet. Do not use an
extension cord when wet. Inspect extension cord thor-
oughly before each use. Do not use if damaged. Uncoil
extension cord and do not cover it with any other material.
