1.2mm 1.5mm 1.6mm 1.8mm 2.0mm
Diameter Round Cooper Electrode Pin for Battery Pack Spot Welding
Machine
The electrode is used for battery pack spot welding machine.
Spot welding between nickel strips, nickel-infiltrated steel
sheets, coated steel strips and other materials in battery
production. In the production of nickel-metal hydride batteries,
nickel-cadmium batteries, polymer batteries, lithium batteries and
other batteries, spot welding connection pieces, cells, and
lead-out pieces.
Features
1. Avoid sticking electrodes.
2. The welding part does not turn yellow, and the welding point is
beautiful.
3. Avoid the phenomenon of virtual welding.
4. Eliminate the phenomenon of welding sparks.
5. Superior electrical conductivity and thermal conductivity.
6. Good high temperature performance.
