After trying this Industrial and Scientific tool, I am extremely disappointed in its performance. Despite the favorable reviews, this product proved to be a complete failure. The only positive aspect is its lightweight design. However, the cons far outweigh any benefits. The machine stopped working after a few uses, leaving me with unfinished projects and a metalworking tool that was not worth the investment. I would not recommend this welding inverter to anyone in need of a reliable industrial power tool.
