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.
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 .
+1 volt DC per 10 volts of output w/respect to pin 11.
+1 volt DC per 100 amperes of output w/respect to pin 11.
With respect to pin 11 (Pin A of 14 pin).
This pin is the signal reference for pins 1, 2, 3, 10, 15, 16.
Paired with Pin 4. Connect to user's external voltage supply common. See
Section 5-5 .
For pins 5 and 6.
Earth ground. Connected only if common potentials are needed between user
equipment and the welder.
Disables the arc starter from being activated when connected to pin 8.
Paired with Pin 22.
Paired with pin 21. Sets output amperage value for a Maxstar and the EN am-
perage value for a Dynasty. Value should be between 0.3 to 10V correspond-
ing to the minimum to maximum of the machine.
Connect to pin 8 to activate this mode.
(Dynasty models only) Paired with Pin 27. Sets EP (cleaning) output amper-
age value. Value should be between 0.3 to 10 volts corresponding to the mini-
mum to maximum of the machine.
(Dynasty models only) Paired with Pin 26.
(Dynasty models only) User controlled polarity (EN or EP), frequency (20-400
HZ) and balance of an AC waveform. When this pin is not connected to pin 8
the weld output is EN. When this pin is connected to pin 8 the weld output is
EP. Alternating between connection and disconnection at different intervals
creates the frequency and balance of the waveform.
