<p>Make: Branson<br>Model: 2000IW<br>Condition: Used, LIKE NEW - EXCELLENT SHAPE!!!<br>2 units available - See Last Picture<br>1 units with amplitude control.<br>1 units without amplitude control.<br>Dimensions: 44.0in x 36.0in x 88.0in.<br>Weight: 300 lbs<br>New without any accessories, the cost was $18,500 each.<br>Extras we purchased were leveling kits and factory installed amplitude controllers.</p>
<p>We used them for less than a year, welding thin layers of polypropylene fabric. They have always been stored in a clean, climate controlled environment and they look new.</p>
<p>Factory info from Branson Site:Specifications: Key Features<br>• Line / Load Regulation - corrects for variations due to power line<br>fluctuations and varying load conditions through Branson’s proprietary<br>closed-loop amplitude control. Output amplitude is maintained with a<br>variation of only + 2% with line voltage fluctuations of +10%, regardless<br>of load. It ensures constant power in welding and provides greater weld<br>consistency and reliability.<br>• 2000 Series 20 kHz converter - produces 20% higher output amplitude than its 900 Series predecessor for faster weld cycles; in addition, this converter is more rugged and has higher power capacity.<br>• Auto Seek - automatically measures stack frequency and stores it in memory. Three selectable Auto Seek choices are available:<br>1. On power up, setting memory for the initial weld.<br>2. Depressing “test” switch.<br>3. By once/minute timer to track heating, cooling, and other effects.<br>• Digital parameter entry with autoranging - when entering parameters<br>gives precise settings for repeatable accuracy. The autoranged values enable fine resolution and setup accuracy.<br>• A linear optical encoder - (IW+ models only) measures weld “distance.”<br>The resolution on the encoder is 0.0001 inch (0.0025 mm).<br>• Afterburst with variable delay and duration - is available to dislodge a part or material adhering to the horn face.<br>• Individual select keys - allow easy selection of parameters to be modified.<br>Active choice is lighted.<br>• Sequence of operation - is displayed in the digital LED window during the welding cycle.<br>• Self-diagnostics and cycle monitoring - features and capabilities provide fast, accurate troubleshooting and minimize downtime. During initial powerup, the unit completes a self-check and identifies any fault conditions or parameter errors before indicating that the system is “ready” for operation.<br>• Visual and audible alarms, and external outputs - identify overload, machine faults and setup errors (e.g., emergency stop engaged).<br>• Fast-response LED storage meter - displays power loading in 5% increments, and provides storage of the peak power achieved during the weld cycle as well as better visibility; 100% of rated output of the power supply is delivered at full meter reading.<br>• Peak power reading - from the last welding cycle is available on the digital<br>LED display by depressing the “reset” switch. Similarly, power in the tuning mode is digitally displayed when the “test” switch is depressed.<br>• LED readouts display parameter settings - during setup and operation<br>for easy reference and monitoring. LEDs are large and easy to read in most light conditions.<br>• Lockout of front panel switches - is provided by and internal dip switch, preventing unauthorized parameter changes to the setup.</p>
