Digital Displays
The digital displays monitor system operation during
welding and provide message code information. See
Figure 3-7. The display functions are as follows:
D
Average Current
indicates the average arc current
measured during the weld sequence.
D
Average Voltage
indicates the average arc voltage
measured during the weld sequence.
The average voltage displayed during a weld cycle
varies with the arc gap, type of shielding gas, current
output, etc., but typically is in the 5 V to 15 V range.
The
Average Current
and
Average Voltage
displays are
also used for programming and displaying message codes.
See
SWS Modes of Operation

SWS Modes of Operation
The front panel controls serve two purposes. In addition to
controlling the weld parameters and weld sequences, the
controls are used to access the modes of the power supply.
The power supply has three modes of operation:
D
operational
D
program
D
test
Each mode uses message codes to perform a variety of
functions. Generally, the message codes are grouped by
mode. Operational mode uses codes 1 to 11, 41, 42, 50,
and 51. Program mode uses 20 to 23, 30 to 35, 60 to 63,
and 99. Test mode uses 97 and 98.
The message codes are explained in detail later in
this section.
Table 3-3 shows all the message codes used by the power
supply. Note that certain code ranges are marked Factory
Use. These codes, except for 64 to 96, are normally not
used, which is noted in the table.
