NOTE: the first batch of products has been shipped and I am currently sold out. I will now allow some time for customer feedback that may result in further improvement. New pre-orders will be accepted by Sept~Oct 2017, and I expect to be able to deliver parts from a second, larger production batch by Oct~Nov 2017.

The assembly and operating manuals are available on this website for download (https://www.kicksurfer.de/index.php/product/assembly-manual/ –  https://www.kicksurfer.de/index.php/product/kweld-operating-manual/). You can purchase them in the shop at no cost as a regular item and will receive a download link.


Purchase this item if you want to receive everything that is needed to build a kWeld kit. Complete the kit using basic tools, add a suitable power source, and start welding.

If you want to source some parts from e.g. your local hardware store, then this article may not give you the necessary flexibility and options; in this case, you can order the individual components from the shop instead, and use the description below for an overview of what is needed to build a complete kit.

The kit includes:

Electronics This is the brain of the kWeld battery spot welder. You purchase a professionally reflow soldered, tested and programmed electronic module. See https://www.kicksurfer.de/index.php/product/kweld-electronics/ for more details.

All SMD and most through-hole components are already mounted. Only the dial potentiometer and the LCD (plus an 11-pin header) come separately when choosing the partly assembled option, to allow the construction of custom housings with remote locations for these components.

Choose the fully assembled option to receive these parts mounted as well.

Cables, electrode holders, and electrodes All bits and pieces that are required to fully assemble the kWeld cabling, including a pair of electrode holders and a pair of electrodes. (See https://www.kicksurfer.de/index.php/product/kweld-cable-electrode-holders/ and https://www.kicksurfer.de/index.php/product/kweld-electrode-set/ for details.) The power input connection consists of loose cable ends, you need to add a connector that matches your power source. Suitable XT150 power connectors are available in the shop.

Choose the raw material option if you have the time and tools do do the necessary machining and assembly steps yourself, saving some money. Check out the assembly manual for an overview of the involved work. If you are in doubt, choose the fully assembled option here.

Fuse A 300A high current fuse (type ANL) that needs to be mounted on the kWeld electronic module and protects the system from the consequences of unlikely catastrophic failures.
Foot switch The pulse trigger switch of the kWeld system. It has a rugged construction, and uses actually a real micro switch that is also easy to service. Cable length is 2.0m, with tinned ends.
Laser-cut aluminum bus bars These need to be bolted to the electronics module and provide a low impedance path between the switch transistors and the cable system.
Mechanical parts All bits and pieces that are required to fully assemble the kWeld electronics module with the LCD, the cabling, the fuse, and the bus bars. See https://www.kicksurfer.de/index.php/product/kweld-mechanical-parts/ for more details.

WARNING:

You are dealing with very high energy levels when using this system, which may result in personal injury or fire when handled improperly. Take appropriate safety measures and use this system with caution. Never leave it unattended while being powered.
