The Weld Graph Program Mode (Figure 1-1) emulates many of the popular word processing programs by
using the front panel cursor keys to easily modify any time period, current, voltage, or power value. The
Weld Graph Run Mode (Figure 1-2) gives the user instant visual feedback on the actual current, voltage
or power used to make each weld.

The Power Supplies exclusive, context sensitive, User Help Screens quickly guide the user through even
the most complex program. Each weld schedule can use any one of 10 different Weld Functions, thus
matching the appropriate weld energy profile to the application.
Simple automated welding control is easily accomplished using the BCD Remote Schedule Select feature.
For more complex automation processes, a host computer can use the Power Supplies Bi-Directional RS-
422 / RS-485 Communications Port to select Control Weld Schedules and receive average weld current
and weld voltage data for each weld. Refer to the separate RS-485 Data Communications Manual, P/N:
990-058, for advanced RS-485 data communications operation. The 2 KHz operating frequency ensures
that the Power Supply Weld Transformers are light weight and compact, providing a significant advantage
when they are built into robotics or automatic machines.
