The post-welding cleanup kit includes a wire brush and a specialized chipping hammer. The hammer is 10.5 inches long and features a spring handle that acts as a shock absorber, enhancing impact efficiency like a mini jackhammer. It's ideal for quickly removing slag from weld seams. The brush, with metal bristles, is suited for gentler cleaning. The hammer is made of hardened steel with a dual head—chisel and pointed tip—for versatile use.
