CODE REQUIREMENTS FOR INPUT CONNECTIONS

WARNING

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.

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.

CAUTION

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).

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 mm2) or larger. The recommended maximum lengths are 25 ft (7.5 m) if #14 AWG (2.1 mm2) is used and 50 ft (15 m) if #12 AWG* (3.3 mm2) is used.
