Dual Pulse - Weld Graph Run Screen
(Figure 6-26)
Weld schedule 009 is pre-programmed at the
factory for Dual Pulse operation. The Power
Supply automatically recognizes the presence of a
Manually or Air Actuated Weld Head before the
first weld is made.

To simultaneously view all pre-programmed time
periods and energy settings, press
CHNG
to select
the Alphanumeric Run screen. The 7 digit Weld
Counter is displayed in the upper right corner.
Note: when programming the Dual Pulse weld
function that uses an Air Actuated Weld Head,
press to scroll the program screen to the right to
access the Down and Hold periods.

PULSATION (Figure 6-28)
Pulsation allows the Power Supply and largest
Transformer to be used for applications normally
requiring more weld energy by pumping in more
total weld heat through the use of many sequential
weld pulses. The first Weld Period is followed by
an alternating sequence of Cool and Weld
Periods. The Pulsation number defines how many
Cool/Weld Periods will follow the first Weld
Period. Using the Pulsation can damage the
crystal structure of the parts by making them more
brittle.

Pulsation 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
