Product Options

Working Voltage:
Gas Condition:
MSK-800W is a CE Certified ultrasonic metal welder with a color touch-screen controller. It is designed for welding stacked electrode sheets (Copper & Aluminum) and tabs onto current collectors to prepare Li-ion pouch cells in R&D laboratories.   (MSK-800W is the updated version for MSK-800 on August 2014.)
If the machine is operated in Ar gas condition please consider MSK-800W-AR. See application notes and select it in the optional bar.

MTI has granted the patent 201920351987.X for the Ultrasonic Tab Welding Machine MSK-800W since November 2019.


  • Welding time, delay time, welding layers...adjustable, click Pic. "Program Setup Interface" to see details.
  • Preset welding programs selectable for Al and Cu (Note: Welding power can be readjusted to fit the needs for welding other types of metals such as Au, Fe, Ni, Ag...);
  • Up to four recipes can be stored in the Al or Cu welding programs. 
  • Amp meter provides instant monitoring of the welding current

Max. Power Consumption
  • 800W  (Max 15 layers)
  • (Please email us to VIEW 4200W version to weld MAX 50 layers)
Welding Area 4mm(L) x 4mm(W)
Welding Head
    • Two sets of the welding heads and welding bases are included for weldinboth aluminum & copper current collectors from 1 to 15 layers
    • One set of the welding head and base is pre-installed.
    • Three head and single long welding head available for high throughput welding for both aluminum and copper current collectors. Please click here for more options.
    Ultrasonic Frequency 40K Hz
    Pneumatic Control (Not included)

    Air pressure at 85 psi is required for the operation (Air Compressor is not included. Please click here to order)

    Attention: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn the installation of a gas regulator.

    Application Note
    • The MSK-800W ultrasonic welder can't be used in the Ar gas condition because electric arc occurs during the process. Use N2 gas if needed.
    • Nickel and Aluminum Tabs can be welded onto different types of current collecting substrates (Aluminum or Copper) when making battery electrodes. 
    • A modified version MSK-800W-AR can be safely used in the Ar gas conditionKF-40 feedthrough is provided which separates the control unit from the glovebox (only welding unit is inside the glovebox) and delivers the operating gas from the gas cylinder (or air compressor) outside the glovebox to the welding unit inside the glove box. Please contact us for the quote of MSK-800W-AR in advance if the Ar gas operating atmosphere will be considered.
    • The compact design enables the operation inside the glove box with an Ar atmosphere where Lithium-SulfurLithium AirLithium Solid-State, or Li-ion half cell will be assembled. Please click the images in below to understand these technologies and how it fits in a glove box.
