GENERATOR/WELDER CONTROLS

See Figure B.1 for the location of the following fea- tures:

1.CURRENT CONTROL DIAL: Adjusts continuous current output. The amperages on the dial corre- spond to the average amperages needed for spe- cific Lincoln welder rods.

2.ELECTRODE SELECTION GUIDE: Provides rec- ommended electrode type, size, and welder out- put setting based on the thickness of the work.

3.WELD OUTPUT TERMINAL (TO ELECTRODE HOLDER) WITH 1/2 - 13 FLANGE NUT: Provides the connection point for either the electrode hold- er or the work cable. (Because the POWER-ARC 4000 is an AC output machine, either output ter- minal can be used for either cable.)

4.WELD OUTPUT TERMINAL (TO WORK) WITH 1/2 - 13 FLANGE NUT: Provides the connection point for either the electrode holder or the work cable. (Because the POWER-ARC 4000 is an AC output machine, either output terminal can be used for either cable.)
