Electroweld Pneumatically Operated Battery Tab Spot Welder with Digital Controller 15KVA (BSP-15P-DC) (Weldability: 0.3mm-3.0mm, 10-34 SWG, 11-33 AWG)

*Weldable Materials-Stainless Steel, Brass, Phosphor, Bronze, Nickel, Alloy Steels

Applications: Specially designed for making precision spot welds required for battery tab welding application. Main application is spot welding tabs or straps to nickel–cadmium, nickel–metal hydride or Lithium-ion battery cells to make batteries. The cells are joined by spot welding thin nickel straps to the battery terminals. Spot welding can keep the battery from getting too hot, as might happen if conventional soldering were done.

-Battery tab welding

-18650 battery pack welding

-18650,26650, 32650 cylindrical Li-battery for EV applications

-E-bike battery welding

-Mobile power bank manufacturing, etc.

Users Include: Users include manufacturers of custom battery packs, for battery pack rebuilding, battery cell tabbing, welding alkaline battery tabs, welding for lithium type cell.

Welding Functionality: The welding process consists of welding of thin nickel plates which connect one battery cell to another in a battery pack using the Battery Tab Spot Welder. This machine uses a dual pulse feature which produces a clean, strong and repetitive weld. The first weld heats the surface and eliminates the contaminant to seat the welding electrode tips. The second pulse produces a second strong weld.

Salient Features: Homogeneous welding spot, small spark, and no black spots. Continuous/variable spot welding with high reliability and excellent performance.

Construction : All machine components fitted on a 1475x860x1350 steel table. Ruggedly designed welding head carrying the upper and lower electrode arms and spring control mechanism fitted on the table. Air cooled Transformer, timer and primary contactor housed in an attractively finished sheet metal steel box mounted on the rear side of the table. Connections from transformer output terminates to the welding head by means of a path of heavy duty cables. Specially designed low leakage reactance, air cooled transformer having specially insulated coils

Adjustment of Electrode Force:Adjustment of Electrode Force via integrated air pressure regulating valve. Upper electrode actuated via a quick follow through device by a heavy duty two-way pneumatic cylinder, controlled by a electrically operated 4-way solenoid valve. Compressed air at 15 to 80 psi (1.06 - 5.62 kgs/cm2) acting on the pneumatic cylinder provides the necessary electrode force.The force adjustment with the electrode is very accurate. The electrode holder is of rugged design for long life and heavy welding cycle operation.

Current Control: Current Control by Transformer Taps. Welding Transformer primary winding provided with taps to allow adjustment of welding current in 6 steps from 55% to 100%. The current can be reduced for the sensitive parts in welding process.
