Parts Loaded
Both Parts in Lower Tooling
The most common arrangement places both parts in the
lower tooling, with the part designed to mate with the upper
tooling placed on top. Some parts are self-aligning, some
have small tabs or breakaway pins and sockets. These are
ideally suited to be loaded together into the lower tooling.
Upper Part in Upper Tooling
Trying to place two parts that are not self–aligning in the
lower tooling in a production environment, can result in
crushed parts if they are not accurately positioned. Parts
which are not self-aligning or present alignment problems
require the upper part to be held in the upper tooling. The
upper tooling may have an optional vacuum retention fea-
ture to hold the part in place. This configuration is shown
in Figure 5-1. The button to activate the vacuum retention
is located either in place of the left operate switch or on
a separate switch housing next to the right operate switch
and reset button.
Initiate Weld Cycle
The operator places parts in the tooling, making sure the
light curtain beam is not obstructed. The operator then
presses either Opti - Touch operate switch to initiate a weld
cycle. The green IN CYCLE indicator (C in Figure 4 - 1),
starts flashing, and the welder executes the currently loaded
setup file. Each setup file determines the weld mode, vibra-
tion amplitude, weld pressure and contains values for all
the required parameters.
Access Door Closes
As soon as the green IN CYCLE indicator starts to flash,
the front access door starts to close. As the door slides
up, hydraulic pressure causes the lift table to begin rising.
During the access door transition, the area protected by the
light curtain beam cannot be broken. If this protected area
is penetrated before the door closed sensor is activated, the
door will immediately stop. To recover from a light curtain
fault, press the Machine Reset button. Reference Section
