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 WELD-PAK 100. Connect this plug to a mating grounded 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 88 amps, 18 Volts, 20% duty cycle (2 minutes of every 10 minutes used for welding).

CABLE

CAUTION

Do not connect the WELD-PAK 100 to an input power supply with a rated voltage that is greater than 125 volts.

Do not remove the power cord ground prong.

Refer to Figure A.6.

The WELD-PAK 100 has a power input cable located on the rear of the machine.

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 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 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 WELD-PAK 100 can be used at an output of 62 amps, 20 volts, 20% duty cycle.
