Atomfair-UWM7320 Ultrasonic Welding Machine
Product Overview
Compact in size, elegant in appearance, easy to operate, sturdy in structure, and stable & safe in use. The transducer converts high-power ultrasonic oscillation signals into mechanical energy of corresponding frequency, applying it to the metal sheet interface to be welded. It instantly heats the joint, activates particles in the metal lattice, and enables molecular interpenetration for firm welding.
Functional Features
- Low internal resistance at welding points with excellent conductivity and ultra-low resistivity close to zero
- No oxidation marks; ultrasonic wave has cleaning function, realizing perfect welding without surface treatment even with contaminants/oxides on metal surfaces
- No pre-treatment for all workpieces, fusion welding without solder or welding oil additives, economical and convenient
- Welding head made of wear-resistant materials with long-lasting durability
- Firm welding points; working temperature below annealing temperature, no change to workpiece metallographic structure, stronger fusion strength than other methods with neat and clean welds
- Low welding cost, fast speed, easy operation and convenient maintenance
- Ultra-short welding time, instant fusion completion generally within 0.01-2 seconds
- No sparks during fusion, safe for operators; no smoke, no air pollution

This document outlines the operational constraints for the Atomfair-UWM7320 ultrasonic welding machine. It requires a stable AC220V/50Hz power supply and a compressed air supply of 0.5-0.7Mpa.
- Power Supply Requirement: The machine must be connected to a stable AC220V/50Hz power source to ensure consistent ultrasonic frequency output.
- Air Pressure Requirement: A compressed air supply of 0.5-0.7Mpa is required for the pneumatic system to function correctly.
- Electrical Power Limit: The input electric power must not exceed 800VA to prevent overloading the ultrasonic generator.
This procedure describes the safe and effective operation of the Atomfair-UWM7320 ultrasonic welding machine. It covers setup, parameter adjustment, and the welding process.
Required Equipment: Atomfair-UWM7320 Ultrasonic Welding Machine, Compressed air supply (0.5-0.7Mpa), AC220V/50Hz power source
- Connect utilities
Connect the machine to a stable AC220V/50Hz power source and a compressed air supply regulated to 0.5-0.7Mpa. - Set welding parameters
Set the welding time on the control box to the desired duration within the 0-1 second range. - Position the workpiece
Place the metal sheets to be welded between the ultrasonic welding head and the anvil, ensuring proper alignment. - Initiate the welding cycle
Activate the welding cycle by pressing the foot switch or the start button on the control panel. - Allow the weld to form
Allow the ultrasonic energy to be applied for the preset time (typically 0.01-2 seconds) to complete the fusion. - Retract the welding head
After the weld is complete, the welding head will automatically retract; remove the welded assembly from the fixture. - Inspect the weld quality
Inspect the weld for uniform fusion, absence of oxidation, and proper joint strength.
What is the maximum welding time and how does it affect the metallurgical structure of the workpiece?
The Atomfair-UWM7320 supports a welding time adjustable from 0 to 1 second, with typical welds completing in 0.01–2 seconds. Because the working temperature remains below the annealing temperature, the workpiece's metallographic structure is not altered, preserving material integrity while achieving fusion strength superior to other methods.
Can the Atomfair-UWM7320 weld oxidized or contaminated metal surfaces without pre-treatment?
Yes, the ultrasonic welding process eliminates the need for surface pre-treatment. The ultrasonic wave provides a cleaning action that removes contaminants and oxides during welding, enabling perfect fusion even on dirty or oxidized surfaces. This is achieved without solder or welding oil, reducing process steps and consumable costs.
What are the utility and air pressure requirements for installing the Atomfair-UWM7320?
The machine requires a standard AC220V/50Hz power supply and a compressed air supply of 0.5–0.7 MPa. It draws up to 800 VA of input power and weighs approximately 60 kg. The control box measures L360×W480×H200 mm and the generator L300×W460×H270 mm, so plan for adequate bench space and a stable air supply.
