I gave a five star rating because I have sent it back and got a refund and I am very happy and would do business with you again. Thank You Review: It worked ok, until it didnt work at all. - I had this unit and assembled successfully several battery packs. It takes some dialing in to get a decent weld and the electrodes burn up kinda quick. My big issue being after welding 175 battery cells the unit fails to fire. I thought I would be ok because its the "top of the line" sunkko. Should have figured. Save the headache and get the Kweld from germany, much better. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07M9JSQ7L | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 3.3 3.3 out of 5 stars (73) | | Date First Available | October 30, 2017 | | Is Discontinued By Manufacturer | No | | Item Weight | 15.32 pounds | | Item model number | 737G+ | | Manufacturer | SUNKKO | | Product Dimensions | 5.51 x 9.84 x 7.87 inches | ## Images ![SUNKKO 737G+ - Image 1](https://m.media-amazon.com/images/I/61ByyZKuLzL.jpg) ![SUNKKO 737G+ - Image 2](https://m.media-amazon.com/images/I/71iTMVwnM+L.jpg) ![SUNKKO 737G+ - Image 3](https://m.media-amazon.com/images/I/61WSwoWswKL.jpg) ![SUNKKO 737G+ - Image 4](https://m.media-amazon.com/images/I/71KotAhx0kL.jpg) ## Questions & Answers **Q: Can I weld nickel strips to aluminum with this welder?** A: From the description 737G+ can weld pure nickel, nickel plated steel, iron etc.. It CANNOT weld copper and aluminum. **Q: do you have this to work in 220V?** A: I use 120v **Q: We are having a problem with inconsistent weld energy. We will get 5 to 30 good welds and then a high power weld ‘pop’ will occur. Why?** A: I get that to sometimes but I found that it usually happends when I'm trying to weld the + of a AA and one of the electrodes is not securely on the tab. It does a good job for me, so far no deal breakers as far as issues. **Q: Does it come with the accessories shown in the picture? Are the nickel strips included?** A: Packing List: 737G+ main machine: 1 pc S70BN mobile welding pen: 1pc Copper welding rods: 2 pairs Mini grinder with USB cable: 1pc Copper welding pins for mobile pen: 1 pair Battery fixture: 1 pc Foot Pedal: 1 pc Fuse: 2 pcs Hexagon wrench: 1 pc 0.15 x 8 x 100 mm (nickel plated steel) 50 pcs 0.1 x 4 x 100 mm (nickel plated steel) 50 pcs Manual: 1pc ## Customer Reviews ### ⭐⭐⭐⭐⭐ Did not work *by T***E on June 26, 2019* it must have been defective because it would not weld the tabs to the battery's I tried all the setting and still nothing.
