5-6. Automation Connection For 28-Pin Receptacle (If Present)
A. Basic Automation Mode
Use this mode when only the basic functions of the automation board are required. These functions include Start/Stop, Valid Arc Indication, Gas
Control, High Frequency Arc Start Disable, and Remote Memory Select. The welding power source functions as a standard unit. Automation 2
mode should be used when an externally controlled pulse waveform is needed, or if the welder’s amperage is affected by noise injected into the
cabling between the remote equipment and the welder.

Description Pin Information For 28–Pin Receptacle RC28
1 Input Start/Stop Maintained connection to pin 8 starts the weld cycle. Opening connection
stops weld cycle. For momentary closure operation, set unit to 2T. A momen-
tary closure greater than 100 ms, but less than 3/4 of a second starts and
stops weld output.
3 Input Gas Control This input is used to control the gas flow outside the settings of the preflow
and/or postflow set on the machine. Connection to pin 8 turns on gas.
4 Output Valid Arc Indication Paired with Pin 9. This output is used to signal external fixtures that the ma-
chine has detected a valid arc. Pin is closed to pin 9 when the output is on
and there is less than 65 load volts. Electrical specifications: Open collector
transistor maximum values 27 volts DC peak @ 75mA. See Section 5-5 .
5 Output Scaled Actual Welding
Voltage +1 volt DC per 10 volts of output w/reference to pin 11.
6 Output Scaled Actual Welding
Amperage +1 volt DC per 100 amperes of output w/reference to pin 11.
7 Output +15 volts DC With respect to pin 11 (Pin A of 14 pin).
8 Output Reference PIN This pin is the signal reference for pins 1, 2, 3, 10, 15, 16.
9 Output Valid Arc Indication
Reference Paired with Pin 4. Connect to user’s external voltage supply common. See
Section 5-5 .
10 Input Memory Select Used to select between memory numbers. Used in conjunction with pin 15
and 16. See Sections 5-7 and 10.
11 Output Amperage Control
Reference For pins 5, 6, 7, 17 and 18 (Pin D of 14 pin).
12 Output Welders Chassis Earth ground. Connected only if common potentials are needed between user
equipment and the welder.
13 Output Arc Length Control
Lockout Paired with Pin 14. Used to send signal to an automatic voltage control to
ignore the voltage during certain situations. Pin is closed to pin 14 when weld
cycle is in Initial Amperage, Initial Slope, Final Slope, Final Amperage, and
Pulsed Background time. Electrical specifications: Open collector transistor
maximum values 27 volts DC peak @ 75mA. See Section 5-5 .
14 Output Arc Length Control Lock-
out Reference Paired with Pin 13. Connect to user’s external voltage supply common. See
Section 5-5 .
15 Input Memory Select Used to select between memory numbers. Used in conjunction with pins 10
and 16. See Sections 5-7 and 10.
16 Input Memory Select Used to select between memory numbers. Used in conjunction with pins 10
and 15. See Sections 5-7 and 10.
17 Input Amperage Control 0 to +10 volts DC with respect to pin 11. The 10 volts represents the amper-
age value set on machines meter (Pin E of 14 pin).
