Overview
A single-needle opposed spot welding machine dedicated to the bottom electrode of 18650 cylindrical cells. The bottom electrode is fixed in a support block carried on a sliding base; the operator pushes the steel can along its slider so that the cell seats onto the upper welding needle, and the weld is then triggered. Output is controlled by a microcomputer, with all parameters entered from the keypad and shown on an LCD.
Key features
- Single-needle opposed welding with a fixed lower electrode and a spring-loaded sliding cell support
- Pneumatic welding head actuated by a photoelectric switch
- Microcomputer control with keypad entry and adjustment of every parameter
- LCD display showing the set values and the live work-piece count
- Welding current adjustable from 0 to 99 percent and welding time from 1.0 to 3.0 ms
- Electrode pressure adjustable from 0.5 to 4 kgf for different can and tab combinations
- Upper electrode 3 mm and lower electrode 6 mm with a 15 mm stroke
- Small welding spark, no discolouration of the weld spot and a clean cell surface after welding
- Short welding time limits the heat-affected zone and keeps the effect on the base metal small
- Suitable for battery tab welding, hardware part welding and tab wire welding
