Ultrasonic hand-held welding units HW35/HW70
The ultrasonic hand-held welding units in the HW series are ideal for spot welding, riveting, flanging and cutting plastics and synthetic textiles.
With their low weight and ergonomic shape, they’re a fantastic addition to any scenario involving manual applications. A user-friendly and cost-effective design make the HW series of ultrasonic hand-held welding units a standout choice for manual workstations.
The horn – which is the actual welding tool – is easy to replace, making it an economical option for performing several applications with the same ultrasonic hand-held welding unit.
Fields of application
Ultrasonic hand-held welding units are used in applications where it does not make sense or is not possible to automate welding or cutting operations, such as test welds in test laboratories.
Typical applications include ultrasonic riveting of car door panels or ultrasonic cutting (trimming) of protruding residual material on A/B/C pillars.
Start trigger
In the HW35, the ultrasound trigger takes the form of a pushbutton on the handle – while the HW70 provides it as a footswitch. However, the HW70 ultrasonic hand-held welding unit can also be integrated into a special machine, in which case an external signal controls the ultrasound trigger.
Status available to view on hand-held unit
An integrated LED features on the rear of the ultrasonic hand-held welding unit, keeping the unit’s status in view at all times. It indicates the status of the ultrasound or the generator itself.
- Green: The unit is ready
- Yellow: Ultrasound is active
- Red: An error has occurred
This makes it easier to monitor the welding process and improves process reliability.
This function has only been integrated into the HW35.
Cutting with template horns
For ultrasonic welding, the horns – which are the cutting tools – are designed and manufactured in line with specific customer requirements. However, our range also includes standard horns. Cutting horns can be rotated 90° to adapt the horn position to the cutting direction.

Advantages of the HW35 and HW70 ultrasonic hand welding units
Versatile use
Ideal for ultrasonic welding, ultrasonic spot welding, ultrasonic riveting, ultrasonic flanging or ultrasonic cutting.
Cutting and sealing in a single operation
Ultrasonic cutting seals the material as it cuts, creating significant time savings in the process.
Welding of the highest quality
The stable structure of the ultrasonic hand-held welding units ensures optimum ultrasound transmission – for welding that’s of outstanding quality.
Durable
Protected cable guide
Integration
The HW70 ultrasonic hand-held welding unit can also be integrated into automation lines.
Design
The ergonomic design of the ultrasonic hand-held welding units is a delight to work with, and there’s even a small, lightweight version available with a 70 kHz operating frequency.
The HW35 set
The HW35 is available in a set with the Ecoline generator, supplied in a carrying case for easy transportation to wherever it is required. The case also comes with service tools included.
Low-maintenance
The ultrasonic hand-held welding units hardly ever require maintenance.
Hanging
For an even better work process, the HW35 can be hung from support fixtures and balancers using the eyelet.
Options
Tool case
We offer the right tools in a handy case for tool changes to ensure that your work processes run smoothly and efficiently.
Retrofit kit
The retrofit kit makes it possible to convert an HW35 into an HT35 and then use it as a hand tacker.
