WELD HEAD TYPE (Figure 7-7)
The Power Supply can be used with a Manual or
Air Actuated Weld Head. Air Actuated means
that the Power Supply will provide a 24 or 115
VAC output which can be used to control an air
valve (solenoid) on an Air Actuated Weld Head.
The Power Supply can automatically detect the

For a complete description on how the
DUAL AIR
option can be used to sequentially control two Air
Actuated Weld Heads, reference Page 17, AMADA WELD TECH Force Fired, Dual Air Actuated Weld
Head System.
FOOTSWITCH TYPE (Figure 7-7)
The Power Supply requires the use of a Single-Level (1-Level) or Two-Level (2-Level) Foot Switch in
order to control an air actuated weld head. The Power Supply automatically detects whether an AMADA
WELD TECH - 1-Level or 2-Level Foot Switch is connected to the Foot Switch Connector located on the
rear panel.
A Single-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 automatically returns the Upper Electrode to its up position.
When a Two-Level Foot Switch is pressed to the first level, 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 operator presses the Foot Switch to the second level, the Power Supply automatically
returns the Upper Electrode to its up position so that the parts can be re-positioned. Once the second level
has been reached and the Force Firing Switch in the Weld Head has closed, Weld Current will flow and
the Power Supply will automatically return the Upper Electrode to its up position.
