The 28kHz 800W Portable Handheld Spot Welder is an advanced industrial tool utilizing high-frequency ultrasonic acoustic vibrations. These vibrations are locally applied to workpieces held together under pressure to create a seamless solid-state weld.

This equipment is widely optimized for nonwoven fabrics, plastics, and joining dissimilar materials. It is particularly effective for embossing and point welding applications such as mask earloops.

Our ultrasonic systems are capable of processing multiple layers of fabric with specialized horn/mould designs:

• Standard 3-layer nonwoven fabric welding (PP Non-woven + Melt-blown filter + PP Non-woven).
• Heavy-duty capability reaching up to 5 or 6 layers of fabric.
• Ideal for disposable medical products and filtration materials.
