LIMITATIONS

•The BULLDOG™ 140 is not recommended for any processes besides those that are normally per- formed using stick welding (SMAW) procedures.

•The BULLDOG™ 140 is not recommended for pipe thawing.

•During welding, generator power is limited to 100 watts, and output voltages can drop from 120 to 80 volts and 240 to 160 volts. Therefore, DO NOT

OPERATE ANY SENSITIVE ELECTRICAL EQUIP- MENT WHILE YOU ARE WELDING.

CONTROLS AND SETTINGS

All welder/generator controls are located on the Output Control Panel. Gasoline engine controls are mounted on the engine. See Figure B.1 and the figures in engine operation section.

4.WELD WORK OUTPUT TERMINAL: Provides the connection point for the work cable.

5.GROUND STUD: Provides a connection point for connecting the machine case to earth ground.

6.240 VOLT RECEPTACLE: Connection point for sup

240 Volt power to operate one electrical device.

7.120 VOLT DUPLEX RECEPTACLES (2): Connection point for supplying 120 Volt power.

8.HOUR METER: Records the time that the engine has run for maintenance purposes.

WELDER/GENERATOR CONTROLS

See Figure B.1 for the location of the following features:

1.CURRENT CONTROL DIAL: Adjusts continuous current output. The amperages on the dial corre- spond to the approximate amperages needed for specific Lincoln welding electrodes.

2.20 AMP CIRCUIT BREAKER: Provide separate over- load current protection for the 120 Volt and 240 Volt Receptacles

3.WELD ELECTRODE OUTPUT TERMINAL: Provides the connection point for the electrode holder cable.
