CODE REQUIREMENTS FOR INPUT CONNECTIONS

WARNING

This welding machine must be connected to a 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 conduc- tors 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 Rated Output

A power cord with a 15 amp, 125 volt, three prong plug (NEMA Type 5-15P) is factory installed on the SP-135T. 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,19 Volts, 20% duty cycle (2 minutes of every 10 minutes used for welding).

CAUTION

Do not connect the SP-135T to an input power supply with a rated voltage that is greater than 125 volts.

Do not remove the power cord ground prong.
