7.2.2 Factory Air Source
Factory air must be turned on, supplying the actuator’s air pressure regulator with air
pressure. If factory air is too low (below 35 psi maintained) the actuator will not weld or
operate reliably. Factory air is also used to provide cooling air to the converter.
Factory air input may affect weld results for applications requiring more weld pressure
buildup.
7.2.3 Downspeed Control
The Downspeed Control regulates the horn velocity. Downspeed has a significant effect on
the force buildup on the workpiece, and hence the quality of the weld.
7.2.4 Actuator Alignment and Height (Horn Travel)
The horn carriage will travel up and down on the actuator’s slides. The actuator can also
be adjusted up or down on the column. The distance between the fixture and horn should
allow easy and ready access and removal of your parts.
• Minimum stroke cannot be less than 1/8”
• Maximum stroke cannot exceed 3-3/4” before part contact to allow for the operation of the
dynamic flow through mechanism
Consistent weld results are best measured when the horn travel is more than 1/4 inch,
because a shorter distance can be affected by other components of the welding system
and a suitable build-up of pressure on the parts.
NOTICE
Factory Air pressure must be greater than the maximum system
requirements. The compressed air system must have sufficient
capacity to serve all of the systems connected to it. The use of an
accumulator may be required to provide continuous air flow.
NOTICE
Set velocity to 1-2”/sec, for an initial setup.
