The Nu-Tec Systems DualSpot and AutoSpot spot welding dent pulling system allows operators to select CD aluminum stud or steel pin and tab welding options in one compact unit. The DualSpot has an aluminum CD gun with M4 and M6 stud capacity with spring ground collar. Additionally, the steel gun has pin, tab, wiggle-wire and heat-shrink tips. The AutoSpot offers manual or automatic operation with a lightweight torch cable for pins, tabs, wiggle-wire or shrink work. Both units come with a Hot Tip slide hammer tool that connects directly to the torch cable, allowing maximum speed of repair as the technician walks the panel and pulls as he welds.
