CONTROL BOXES

For use in connecting the AEC 200 Welding Gun to constant current (DC Stick or DC Tig) welding power source.

TO INSTALL:

1.) Remove top cover from control unit.
2.) Install the multi-conductor cord from the AEC 200 Welding Gun through the access hole in the front

panel of the control box and connect the numbered wires to the corresponding numbers on the 8 pole
terminal strip TS1.

3.) For power sources with an internal contactor, connect a two conductor cord from TS2 in the

control box, to the contactor control receptacle on the welding power source. (See note below).

4.) Connect the 115 volt A.C. power cord from the control box to a 115 volt A.C. power source.
5.) Replace top cover and tighten screws.
6.) Connect a welding cable (1/0 or 2/0) from the positive output terminal on the power source to the

"Electrode" stud terminal on the control box.

7.) Connect the small black sensor lead from the control box to the negative output terminal on the

welding power source. (Same terminal the work lead is connected to)

8.) Connect the power cable lug of the AEC 200 Welding Gun to the "GUN" stud terminal on the control box.

NOTE

Terminals 1 and 2 on the four pole terminal strip TS2 are for use with welding power sources requiring a normally open set of
contacts for power source contactor operation. This set of contacts will close when the gun switch is operated.

Terminals 3 and 4 on the four pole terminal strip are for use with welding power sources requiring 115 VAC to be supplied to the
power source for contactor operation.

The contactor control cord is not included with control and is sold as an option. Order part no. 6182 if you require contactor cord.
