(Figure 6-17)
Weld schedule 006 is pre-programmed at the
factory for Braze operation. The Power Supply
automatically recognizes the presence of a
Manually or Air Actuated Weld Head before the
first weld is made.

ROLLSPOT (Figure 6-19)
Rollspot is a special form of seam welding.
Typically, upper and lower wheel electrodes, in
conjunction with an automatic parts feeder, are
used to make a Rollspot weld. Because of the
weld current shunting effect after the first weld,
set the Weld2 Period weld current greater than
Weld1 by a factor of 20% to 50%. Use the larger
percentage for closer spacing. Assuming the
rotational speed of the wheel is fixed, the Weld2
Period controls the length of the spot and the Cool
Period controls the distance between spots.

CAUTION:
It is easy to exceed the duty cycle rating for the Transformer using the Rollspot weld
function. Refer to
Chapter 2, HF2 Weld Transformer Electrical Specifications
.
Rollspot 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.
