CODE REQUIREMENTS FOR INPUT
CONNECTIONS
This welding machine must be connected to
power source in accordance with applicable elec-
trical codes.
The United States National Electrical Code (Article
630-B, 1990 Edition) provides standards for amperage
handling capability of supply conductors based on
duty cycle of the welding source.
If there is any question about the installation meeting
applicable electrical code requirements, consult a
qualified electrician.
Do not connect the SP-100 to an input power sup-
ply with a rated voltage that is greater than 125
volts.
Do not remove the power cord ground prong.
REQUIREMENTS FOR RATED OUTPUT
A power cord with a 15 amp, 125 volt, three prong
plug (NEMA Type 5-15P) is factory installed on the
SP-100. Connect this plug to a mating grounded
receptacle which is connected to a 20 amp branch cir-
cuit with a nominal voltage rating of 115 to 125 volts,
60 Hertz, AC only.
The rated output with this installation is 90 amps, 18
Volts, 20% duty cycle (2 minutes of every 10 minutes
used for welding).
REQUIREMENTS FOR MAXIMUM OUTPUT
An optional power cord (K467 Input Line Cord) is
available to permit the SP-100 to be connected to a
25 amp branch circuit with a nominal voltage rating of
115 to 125 volts, 60 Hertz, AC only. With this installa-
tion the SP-100 can be used at an output of 100
amps, 17 volts, 30% duty cycle.
Refer to the ACCESSORIES section for specific infor-
mation about the K467 Input Line Cord
REQUIREMENTS FOR CSA RATED OUTPUT
A line cord with a 15 amp, 125 volt, three-prong plug
(NEMA Type 5-15P) is factory installed. Connect this
plug to a mating grounded receptacle which is con-
nected to a 15 amp branch circuit with a nominal volt-
age rating of 115 volts to 125 volts, 60 hertz, AC only.
With this installation, the SP-100 can be used at an
output of 63 amps, 20 volts, 20% duty cycle.
EXTENTION CORD USAGE
If an extension cord is required, use one that is rated
for the application and is 3 conductor #14 AWG (2.1
mm
2
) or larger. The recommended maximum lengths
are 25 ft (7.5 m) if #14 AWG (2.1 mm
2
) is used and
50 ft (15 m) if #12 AWG* (3.3 mm
2
) is used.
