No instructions included. Don’t know how to use it. *by M***L on Reviewed in the United Kingdom on 25 November 2020* Not sure how to use this to spot welder to tack strips to 18650 batteries.I connected it to my 11.1v / 3,000mAh Li-pro battery with the crocodile clips and although it did do a weak tack on a strip on a battery, it completely melted the thick crocodile clip wires.It basically just shorts the positive and negative from the battery through the prongs, therefore resulting in the power wires getting very hot and melting.Maybe in need to use jump leads and a car battery with the heavy duty wires in the jump leads.Don’t know what the little plug is for that’s coming out of the device. There are no instructions included, so it’s all guess work.If you know how to use this then I’m sure it’s great, but with no instructions I don’t know how rounds it and it melts my wires. ### ⭐⭐⭐⭐⭐ Very good well worth product *by D***R on Reviewed in the United Kingdom on 4 January 2021* The product arrived today on time and delivered with care. opening the package.... perfectly packed, build quality superb You even get spare parts that might fail down the line.2x spare springs and 2x micro switches along with a key used to replace electrodes and fit power cables.***NOTE! *** I've read other people's comments on this product, some not very good. This is due to people's understanding of how this tool works.Other items required....A strong 12v power supply in excess of 100a and control relay to switch the supply on/off during welding.Without doubt this tool is well worth the money for build quality alone.Very satisfied. ### ⭐⭐⭐⭐⭐ very good *by W***E on Reviewed in the United Kingdom on 19 August 2020* very good to use lasts well --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/188154083-diy-spot-welder-battery-pen-kecheer-battery-welder-pen-integrated](https://www.desertcart.vn/products/188154083-diy-spot-welder-battery-pen-kecheer-battery-welder-pen-integrated) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
