Welder - Available for immediate acquisition: a premium Branson 2000iw Integrated Ultrasonic Welder. Operating at 20 kHz, this high-performance system combines the power supply, digital controller, and pneumatic actuator into a single, compact benchtop footprint. Engineered for maximum precision and repeatability, it is the industry standard for high-strength plastic assembly, staking, and hermetic sealing in medical device manufacturing, automotive components, optics, and electronics. It creates permanent chemical-free hermetic seals for various plastics.

Key Features and Highlights:
All-In-One Compact Design: Integrated power supply and pneumatic actuator minimize bench space and eliminate external cabling mess.
Tri-Mode Welding: Supports precise Weld-by-Time, Weld-by-Absolute-Distance, and Weld-by-Collapse Distance for tight-tolerance part geometries.
Dynamic Triggering: Automatically initiates ultrasonic energy only after a preset mechanical force is achieved, eliminating cold joints.
Closed-Loop Amplitude Control: Patented Branson technology automatically corrects for voltage and load fluctuations to guarantee consistent energy delivery.
High-Precision Linear Encoder: Features an internal optical encoder with a resolution of 0.0001” (0.0025 mm) for fast, hyper-accurate weld depth control with an incredible accuracy of 1/30th the diameter of a human hair!

Other accessories included:
Condenser (removable part of stack but always used) P/N CJ 20 101-135-059
Leveling plate (either metric or imperial) P/N 101-063-xxx ($1260 USD)
1:2 Booster (silver – clear anodized aluminum) P/N 101-149-053 ($1020 USD)
1:1.5 Booster (gold anodized aluminum) P/N 101-149-052 ($1020 USD)
1:1 Booster (titanium) P/N 101-149-096 ($1547 USD for a used booster)
2.5” horn P/N 308-001-021 (titanium, no online price found)
1.25” horn no P/N label (anodization makes it difficult to tell if it is hard aluminum or titanium)

Included Air System - The Branson 2000iw uses both electricity and compressed air for the pneumatic piston. It is important to have dry air for longevity of tools that use pneumatics. I purchased a suitable solution that has an automated release valve to drain condensed water vapor every time we run our compressor and an inline commercial desiccant dryer. The cost of these components is a few thousand dollars.

Air system includes:
Ingersoll Rand compressor on wheels
Automatic tank bleed valve drains tank each day of any condensed water
Desiccant dryer for entire system
6 lab shutoff/regulator/gauge air drops for equipment arranged in three pairs
High pressure tubing and square lab channel to air drops
