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 Rated Output

A power cord with a 15 amp, 125 volt, three prong plug (NEMA Type 5-15P) is factory installed on the SP-135 PLUS. Connect this plug to a mating ground- ed receptacle which is connected to a 20 amp branch circuit 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).

CAUTION

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

Do not remove the power cord ground prong.

Requirements For Maximum Output

In order to utilize the maximum output capability of the machine, a branch circuit capable of 25 amps at 115 to 125 volts, 60 Hertz is required. This generally applies when welding steel that is equal to or greater than 12 gauge, 0.105” (2.5 mm) in thickness.
