HYDDNice 86Pcs Stud Welder Dent Puller Spot Welding Pulling Repair Tools Kit Set for Truck SUV

Either I missed it or the description was not clear enough to let me know that this welder requires a separate welding source. I did not want to have to purchase one so, I returned the kit.

Did not come with everything pictured but will try to use anyway

I need to know what gun I need to use this product
