Handheld Ultrasonic Spot Welder

Product Overview

Our Handheld Ultrasonic Spot Welder is a compact, portable solution for precision plastic spot welding, riveting, and joining applications. With frequency options of 28kHz, 30kHz, 35kHz, and 40kHz, this versatile gun-style welder delivers reliable performance for small-part assembly, prototyping, and on-site production tasks. Lightweight ergonomic design ensures operator comfort during extended use.

Key Features

1. Multiple Frequency Options

Available in 28 KHz, 30 KHz, 35 KHz, and 40 KHz — select the optimal frequency for your material thickness, weld size, and application requirements.

2. Portable Handheld Design

Ergonomic gun-style body with lightweight construction — easy to maneuver, ideal for spot welding on large assemblies, hard-to-reach areas, and flexible production layouts.

3. Precision Spot Welding

Delivers focused ultrasonic energy for clean, consistent spot welds — perfect for plastic riveting, stud welding, dot bonding, and localized joining without consumables.

4. Digital Time Control

Adjustable welding time settings for repeatable results across different materials and production batches.

5. Automatic Frequency Tracking

Built-in auto-tuning system maintains optimal resonance frequency during operation, ensuring consistent weld quality and extending transducer lifespan.

6. Fast & Efficient

Instant welding (typically 0.1–1 second per spot) with no warm-up time required — significantly faster than adhesive bonding or thermal pressing.

7. Wide Material Compatibility

Suitable for most thermoplastics including ABS, PP, PE, PC, PMMA, nylon, and PET — ideal for electronics, automotive interiors, packaging, and textile welding.
