Our 350 Watt, USP-3-HT, Ultrasonic Soldering Pot

This Ultrasonic Soldering Pot, M/N: USP-3-HT, has been built for High-Temperature Operation for temperatures above 600F (315C). We use a "Dual-Loop", proportional solid state PID Temperature Controller. One loop monitors the heater's sheath temperature to ensure that the heaters will not fail due to overheating. The second loop monitors the Melt Temperature and is adjustable for operation at your desired set point. The "Dual-Loop" controller essentially eliminates premature heater failures.

Fluxless Soldering via Ultrasonics

We have mastered the technique for Fluxless Soldering of Stranded or Braided Wire. Our typical Ultrasonic Soldering Pot has the ultrasonic energy source originating from the bottom of the molten solder. Our Wire Tinning System has the ultrasonic energy source located on the sidewalls of the Soldering Chamber, thus delivering more ultrasonic energy to the location requiring the ultrasonic energy. This new technique allows us to solder components that just could not be soldered before.


Our Wire Tinning System Installed on a
350 Watt, USP-3-WTS-5/8", Ultrasonic Soldering Pot

This Ultrasonic Soldering Pot has been built with our Wire Tinning System feature installed. This sytem is ideal for soldering fine wires, cable overbraids, solid core and stranded wire. We even solder very small components or can use very expensive solder alloys due to the low capacity of the WTS Soldering Chamber.

A Customized Wire Tinning System


We offer the opprtunity to build a customized soldering system that is better suited for your production needs. This system's base has a rectangular footprint to minimize the work surface countertop space usage. We installed "Bolt-Down-Tabs" to secure the Soldering Pot so it cannot tip over.

The Narrow Heat Control Cabinet allows the Ultrasonic Generator and Heat Control Cabinet to sit side-by-side rather than on-top-of-one-another. The Heat Control Cabinet can be packaged either short and long or tall and narrow.

The electronic cabinets have been fitted with our optional Tamper Proof Control Guards. These guards prevent unauthorized control adjustments. This feature ensures that only authorized personnel can make process adjustments. With your request, we will mount controls inside our NEMA-12 Generator Enclosure for our very large production systems,

All of our small Ultrasonic Soldering Pots are are built for table top operation or Through-the Counter-Top-Mounting Through-the-Counter-Top Mounting offers the advantage of placing the bulk portion of the Soldering Pot below the Work Station's Work Surface. This arrangement makes it much easier to access the Soldering Chamber for the Soldering Task. When we couple "Through-the-Counter-Top-Mounting" with the "Primary Temperature Controller's Thermpcouple Sensor located inside the system's shroud", we create a sytem that offers superior production performance.

These units are built so you can separate the tank assembly from the shroud.

Benefits provided by Ultrasonic Soldering Include:

The ultrasonic energy micro-etches the substrate providing more tooth and increased bond    strength.
Micro-etching action is accomplished in several seconds.
The soldering alloy's relative viscosity is reduced when acoustically activated.
The soldering alloy rapidly wets the clean surface providing a uniform bond with superior    performance.
The ultrasonic energy draws the solder into the pores of the immersed item.
Uniform wetting without the use of a soldering flux. Postsoldering cleaning eliminated.


Ultrasonic Soldering maximizes the effectveness of many joint designs. Sometimes flux is necessary due to the base materials chosen.  Ultrasonic Soldering allows for a reduction in the chemical strength of the required flux while improving overall performance.

Wide range of melt temperatures available.
Wide range of soldering alloys available.
Open top operation.
Consistent and uniform results.

Usp-3605, 2003

This Ultrasonic Soldering Pot, M/N: USP-3605R (aka L/C-720L)
is still used in Production for 2 Shifts/Day.

This system design is highly effective in soldering Heater Exchangers with aluminum return bends using the ALCOA 571 Process. The USP-3605R is a round bottom soldering vessel. The circular cross-section focuses ultrasonic energy into the center of the molten bath. Upon immersion, the concentration of ultrasonic energy accelerates oxide removal. The immersed item is uniformly wetted with an intermetallic bond between the base material and the soldering alloy.

Built in 2017


This USP-3605R Ultrasonic Soldering Pot System
has a separate NEMA-12 Main Disconnect Switch & Heat Control Enclosure and a NEMA-12 Generator Electrical Enclosure.

The new design for the USP-3605R has been technologically refined to deliver surpassed performance. The permanent output performance of our silver-brazed Magnetostrictive Transducers along with the transducer's high curie temperature provides many years of reliable service.

This particular Ultrasonic Soldering System is built to conform with OSHA's Arc Flash requirements. We locate the high voltage components in a separate electrical enclosure so periodic maintenance can be conducted in an electrical enclosure powered by 250 VAC (and lower). This technique allows the personnel to service the equipment safely without the cumbersome safety equipment required for servicing high-voltage hardware.

We have even replaced the Turbine Cooling Blower with internal mounted blowers that provide quiet operation with a small Factory Floor footprint.

We now provide (3) Ammeters to monitor the Heater Current drawn on our larger systems. This feature allows the Maintenance Department to plan when to service the heaters.

The USP-2408 Being Used in a Bain-Marie Set-Up

The Ultrasonic Soldering Pot can be used to solder with other soldering alloys when used in a Bain-Marie set-up (aka similar to a heated bath where the working fluid has been replaced with molten solder). The ultrasonic sound waves & heat pass through the working solder into the Immersed container. The Immersed Container can contain a different solder, thus giving you the ability to process your material with different soldering alloys without loading an entire Pot with the new Alloy.

Please exercise caution and wear the proper protective clothing when using this soldering method. This method should be used for R&D trials only and not for production purposes.
