Operational Safety
The service doors are interlocked to prevent access while
the welder is energized. The electrical cabinet service door
is shown in Figure 2-7. It cannot be opened without first
turning off the CE-compliant AC disconnect. The rear
service doors are shown in Figure 2-8 and Figure 2-9.
The front loading area is protected by a sliding access
door. This door is operated by two air cylinders which
are driven by compressed air. The doors raise at the
start of a welding cycle to prevent access to the tooling
and lift table. The doors also serve as part of the sound
enclosure. Sensors on the access doors will stop the
welder if the compressed air fails and allows the doors
to open partially during a weld cycle.
The safety light curtains prevent any access to the loading
area once the machine cycle has started and before the
access doors are fully closed. Breaking the light beam
while the doors are in transition will cause the machine
to halt operation. The light curtains are identified in
Figure 2-7.
