and all motor drives. Also located on the door the primary power panel is the service
disconnect breaker, which is used to energize and de-energize the SEAMTEK 36. On the
operator side of the Primary Power Panel is an Emergency Stop button. Pushing this button will
instantly shut off all power and release all compressed air form the machine.
Caution: Pressing The Emergency Stop button will shut off the machine
entirely without allowing the heating element to complete its automatic 3-
minute cool down cycle. This could cause the heater element to be
destroyed or severely shorten its life expectancy. Only use the E-Stop for
emergency purposes
2.2.1 Graphite Vane Air Pump
Directly beneath the Primary Power Panel is the graphite vane air pump. The pump delivers a
constant volume and pressure of airflow to a AHAM and finally to the welding nozzle. This
pump is designed to operate for thousands of hours, delivering a steady stream of clean air
with a minor amount of maintenance. This pump eliminates the need for large in house air
compressors and the expensive drying systems needed to clean that air. Only a small air
compressor is needed to operate the SEAMTEK 36 pneumatic air cylinders. When the SEAMTEK
36 is to be shut down for the day the pump will complete a 3-minute cool down cycle to cool
the heater element. This will help extend the life of the heater elements.
2.3 Upper Beam Design and Construction
The upper beam assembly is constructed from high strength, lightweight, slotted, aluminum
extrusion. This design allows easy side-to-side adjustment of the position of the various
modules that attach to the upper beam.
2.3.1 Upper Beam Fasteners
The surfaces of the upper beam extrusion are not flat; instead, they are slightly recessed next to
the slots. In this way, when a flat object is bolted to the extrusion face, the extrusion acts as a
spring acting against the threads of the nut and bolt. This means that a very secure joint can be
achieved with a minimal tightening of the nut—typically 1/2 to 3/4 turns after finger tight is
adequate.
2.4 Control Module
Mounted in the beam is the control module. It houses the touch screen operator interface. This
is a flat panel display screen that shows the majority of the machines controls and feedback
information. The screen is pressure sensitive. To make adjustments to the welding process the
operator actually touches the images of buttons on the screen itself. The screen may change
