Weld by Distance
The weld cycle is determined by the bottom stop
setting. The End–Of–Weld optical switch stops the
process 0.005” above the actual setting to compen-
sate for the system momentum.
Tooling Capacity
Upper Hub
The upper hub can safely accommodate a maximum
tool nest diameter of 12 inches (305mm) which al-
lows for a clearance of 0.22 inches (5.6mm) in the
back. This is shown in Figure 7–1.
Lower Fixture
The platen surface is 410mm wide (16.14”) by
347mm deep (13.66”). The fixture mounting holes
are shown in detail in Figure 11–3, and consist of
eight M10 x 1.5 2B tapped holes on three bolt circles
ranging from 7.00” to 12.00” diameter. Depending
upon the geometry of the fixture, there is between
7.63” and 8.50” available behind the hub center line.
See Figure 7–1 for the relevant dimensions.
Fixture Height
The following measurements are taken with a
0.5” thick tooling hub, the AC power ON and the
counterbalance regulator adjusted so that the motor
and hub are fully retracted upward. The adjustment
range is achieved by unlocking the dovetail locks
and rotating the hand crank. The normal maximum
height between the platen and upper hub available
is 20.94” (see Figure 7–1). This can be adjusted
at the factory during assembly to a larger capacity
of 26.94” to accommodate unusually high fixture
requirements. The lowest adjustment height (with
the motor and hub retracted) between the platen and
the upper tool hub is 9.19” (15.19” with the extra
height modification). The total stroke available dur-
ing welding is determined by the air cylinder and
