Desk-Top Battery Pack Tab Spot Welder - MSK-330P

Please email for lead time
Item Number: MSK-330P
MSK-330P is a tab Spot Welder for making a larger battery pack manually. It is designed for the production of battery pack manufacturers (Alkaline, NiMH. NiCd, Li-Ion/LiMnNi. LifePO4, NMC) with more reliable and consistent welding.
It could be used for AA / AAA / C / D / F/ M / 10440 / 14430 / 14500 / 14650 / 17500 / 18650 / 26650 / 38120 / 40160 sizes of batteries. 

  • Pneumatic System with foot panel for faster operation
  • Microcomputer single-chip control, the welder may achieve single-pulse, double-pulse, or multi-pulse welding and can weld tab up to 0.5 mm
  • Adjustable welding head ( up and down ) for easy operation
Working Voltage
  • 208-240V AC, 50/60Hz (110V is available via a transformer)
Output Power
  • 15 KVA
  • Programmable Dual Welding Process
  • Variable Height of Welding Head Adjustment
  • Support nickel-plated tab thickness up to 0.5mm
  • Independently adjust for the pressure of two welding probes, ensuring stable and reliable welding pressure
  • Small heat affected weld zones
  • Capable of extremely fine energy adjustment; Current: 0-99% Adjustable 
Welding probes
  • Allow independent adjustment for pressure
  • Ensure consistent welding pressure
  • Fully eliminates the phenomenon of low voltage or condensation occurred to lithium batteries after welding
  • Homogeneous welding spot, small spark, and no black spots, and stable welding current
  • Quick energy release for welding highly conductive metals such as copper
  • Small heat affected weld zones
Welding Switch
  • Built-in optoelectronic welding switch, which can eliminate the need of changing switches for similar welding machines

  • Digital LED control panel for setting all parameters
  • All parameters are set via microcomputer.
  • Adopts LCD display and keypad adjustment, resulting in accuracy, visualization, and easy operation
  • Pre-welding time:          0 - 99 ms
  • Welding time:                0 - 999 ms
  • Welding current:       1- 30A
Tab Thickness Applicable
  • 0.2 - 0.5mm thickness tab
  • (10 pcs 0.2mm Tab will be provided in the package for customer's practice)
Pneumatic Control (Not included)
  • Air pressure at 0.2Mpa ~ 0.8Mpa 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.

  • Max. Depth is 8.5cm (measured from the center of the bottom stage till the backend of the machine)
Safety Protection
  • Fuse to Protect Over Current
  • Warning Lights for Switch device / Weld Head Transformer / Air Supply
  • CE certified
  • NRTL / CSA certification is available upon request at the extra cost.
  • One year limited warranty with lifetime support
  • Rusting and damage due to improper storage condition or maintenance is not covered by warranty

Operation Manual & Video

Application Notes
  • Welding current can be as high as 600A, voltage is 6V
  • Please click here to learn the basic knowledge of Capacitive Discharge Spot Welder
  • Avoid touching weld spots immediately after the weld has been performed as they will be hot
  • Always wear safety glasses when working with spot welders and weld heads
  • Be careful not to pinch fingers in moving weld head parts or between welding electrodes
  • Remove hand jewelry before welding
