Awesome! It’s really easy to use! When welding leaks, clean the equipment, then polish the hole to be repaired, use a windproof lighter to heat the location to be repaired, then take out the welding rod, melt it immediately, then use a windproof lighter to heat the uneven surface to make it flow. Flat surface, do not burn. That’s it. My cooking pot has a hole because it hasn’t been used for a long time. This picture has just been repaired. Like it, like it, like it, like it!
