Cordless Welder
The cordless welder uses a number of 6s 18650 battery packs. The 18650 cells are combined using a clamping system as opposed to soldering or spot welding. Instead, modular holders with flexible elements, press fit, and bolts or set screws are used to hold batteries in place. The batteries can be removed without having to solder and unsolder. The pack geometry and modular holders are 3D printed. The battery is designed with interconnects so that the battery can be stacked either in series or parallel.
Battery Packs
Cordless Welder
To obtain a cordless welder, a 200A aluminum bus bar (1/2" bar stock) is used to connect 24v batteries in parallel.
Universal Controller is used to control the current via the control knob.
