One of the major focuses of the maker movement since time immemorial has been the development of a makeshift version of tools with the goal of making them cheaper and more accessible. This focus has been more pronounced in recent times with several tools like CNC and 3Dprinters being all open-source, decentralized, and affordable to regular folks. To take things further to more machine tools, Canada-based battery refurbishing company; RePowered Batteries, recently announced the launch of their Nano Ultra-Compact Spot welder, which is aimed at making welding more accessible to hobbyists.
Sharing the reason behind the development of the Spot Welder, the team at RePowered Batteries said that the primary “goal is to make a no-hassle and affordable welder” that surpasses the current welders in the market by being both cordless (no external power supply required) and more efficient and safe compared to similar devices on the market.
The Ultra-Compact Spot Welder is comprised of a small built-in DC-DC power regulator, high-quality supercapacitors, and a welding control board on a PCB with 15x more copper than standard PCB, all packaged in a 3D-printed housing, with a selection of welding tips and air-cooled electrodes as consumables.
Built with versatility in mind, unlike other similar solutions in the market, the Spot Welder allows users to weld up to 0.15mm solid nickel. A table showing how the weather further compares with similar devices in the market is shown below:
While the goal is to make the device handy and untethered, one way to power the device is via the use of a 9v external power supply which could be useful, when you need to get things done, fast. However, if you are not in a hurry and not out of battery power, there are several other ways to power the devices including; power over USB or by hooking up a single 18650 battery cell to it.
