Seam can be used with AMADA WELD TECH Force Fired Manual or Air Actuated Weld Heads. For
Manually Actuated Weld Heads, weld current begins when the Force Firing Switch closes. For Force
Fired Air Actuated Weld Heads, weld current begins when both levels of a two-level Foot Switch are
closed and the Force Firing Switch in the Air Actuated Weld Head closes.
When Seam is used with a Non-Force Fired Air Actuated Weld Head, the Squeeze (SQZ) Period must be
used to allow sufficient time for the electrodes to close and apply the required weld force to the parts
before the Weld Period begins. Weld current begins when the Squeeze Period ends and both levels of a
two-level Foot Switch are closed. Weld Current flows as long as all switches remain closed. Hold Period
has no meaning with Manually Actuated Weld Heads and does not appear on either the weld schedule
Program or Run screens.

Weld schedule 008 is pre-programmed at the
factory for Seam operation. The Power Supply
automatically recognizes the presence of a
Manually or Air Actuated Weld Head before the
first weld is made.
