> Introduction
Thank you for your choosing of US-511 which is manufactured by H&H.
The US-511 ultrasonic rotary welding machine was specially designed for cutting and welding
different type of fabric. Various operations such as “line bonding”, anti-fray cutting, button hole
opening can be carried out using US-511.
In order to fully understand how to use this machine properly, and avoid damage to both the machine
and operating personnel, please read this manual carefully and keep it safe for future reference.

> Principle of Seam Sealing
Ultrasonic energy is a form of physical vibration. The commonly used vibration frequencies are 20kHz,
30kHz, 35kHz and 40kHz. Different materials exhibit different behaviors under ultrasonic vibration. Synthetic
material generates internal heat under ultrasonic vibration. The US-511 machine generates vibration on the
surface of the horn. Fabric with at least 50% synthetic material is placed on the surface of the horn. A special
tool called cutter bit is pressed against the horn so that fabric between the horn and the cutter bit is exposed
to vibration. The heat generated in the fabric portion under pressure is heated up instantly and the
temperature is high enough to melt the fabric, hence resulting in an ultrasonic cut.
US-511 is engineered to careful manage this vibrating energy in order to slice fabric consistently in single
layer or multi-layer application.
During single layer operation, fabric is melted and separated resulting in a fray free edge. While during
multi-layer operation, layers of fabrics are cut but at the same time the edges of the fabrics are melted and
fused together resulting in a “weld”. This process is sometimes referred as a “cut and seal” or “line bonding”
operation.

> Preparation for Installation
Installation must be carried out by authorized personnel. Follow the steps below:
1. Position the machine on a flat surface and allow at least 50cm clearance on both sides as well as
the back side, this is essential for the hot air ventilation and also to allow enough room for
maintenance personnel to carry out necessary service and maintenance.
2. Adjust the foot stand so that the machine is level and stable.
3. Loosen all packing cable ties and materials in order to free up all machine movements.
4. Connect the power plug to a suitable outlet with at least 10A capacity. Make sure grounded and
reliable.
5. Locate the air hose supplied with the machine. Connect one end to the inlet of the compressed air
water filter at the back side of the machine; connect the other end to a compressed air supply such
as air compressor or central air supply. Make sure the compressed air supply has at least 0.4Mpa (4
bar) of pressure.
