AIR VALVE 1 and AIR VALVE 2 Driver Connectors (Figure 4-11 and Figure 4-12)
Air Valve 1 Driver (Figures 4-11 and 4-12)
Each Air Valve Driver uses a 4-pin black plastic
TE Connectivity 206430-1 (AWTA Part # 550-
062) bulkhead connector. The mating plug is a
TE Connectivity 206429-1 (AWTA Part # 520-
107) which uses a cable clamp, TE Connectivity
206358-2 (AWTA Part # 245-084) and 3 male
pins TE Connectivity 66361-2 (AWTA Part #
253-055). When using a non-AMADA WELD
TECH Air Actuated Weld Head, connect Pin 2 to
Pin 4. The Power Supply can sequentially operate
two separate Air Actuated Weld Heads using Air
Valve 1 Driver and Air Valve 2 Driver outputs.
Figure 4-11. 115 VAC Weld Head Solenoid
Air Valve 1 Driver (Figures 4-11 and 4-12)
The output of Air Valve 1 Driver is 12 VA at 115
or 24 volts VAC. The Power Supply automatically
applies the correct solenoid voltage to the Air
Actuated Weld Head connected to the Air Valve 1
Driver.
Air Valve 2 Driver (Figure 4-12)
Air Valve 2 Driver provides 24 VAC at 12 VA to
power a second Air Actuated Weld Head. To
provide 24 VAC to Air Valve 2 Driver, jumpers
E10 and E11 on the control board must be moved
to the correct positions. Refer to
Chapter 3,
AMADA WELD TECH, Force Fired, Dual Air

Actuated Weld Head System
for complete instructions to set up and operate two sequential action Air
Actuated Weld Heads. Note: When Air Valve 2 Driver is used, Relay K1 cannot be used for marking
weld periods or activating alarm conditions.
