Weld Head Set-up (Figure 3-2)
1
Adjust the Weld Head Force Adjust Knob
to produce 5 units of force as displayed on
the Force Indicator. For a complete
description of force control and its effect
on the welding process, please refer to
your Weld Head manual.

Install electrodes in Weld Head Electrode
Holders.

Connect a properly filtered air line to the
Inlet Air Line on the Weld Head Air
Valve Driver Solenoid assembly which is
located on the back of the Weld Head.

with automated installations. Turn on the air system and check for leaks.
Firing Switch Cable Connection (Figure 3-2)
Connect the Weld Head Firing Switch Cable Connector to the matching cable connector on the rear of the
Power Supply.
Weld Head Valve Driver No. 1 Connection (Figure 3-2)
A single air actuated Weld Head has one Solenoid Valve Driver Cable for automatic actuation and timing
control by the Power Supply. The Power Supply will automatically recognize the solenoid voltage of the
Weld Head. Connect the 4 pin black plastic connector on the cable to the matching Air Valve 1 Driver
connector located on the Power Supply rear panel.
Foot Switch Connection (Figure 3-2)
1
Connect a Model FS1L, 1-Level, or a Model FS2L, 2-Level Foot Switch to the FOOT SWITCH
connector located on the Power Supply rear panel. The Power Supply will automatically
recognize which model of AMADA WELD TECH Foot Switch has been connected.

1- Level Foot Switch
- The l-Level Foot Switch must be fully depressed by the operator. When
the Foot Switch closes, the Power Supply energizes the Air Actuated Weld Head, causing the
Upper Electrode to descend and apply force to the parts. If the Foot Switch is released before
the Weld Head applies the Preset Firing Force, the Power Supply will automatically return the
Upper Electrode to its up position.
