The Faithfull 4 Piece Sheet Metal Welding Clamp Set is designed for precisely aligning sheet metal panels edge-to-edge and surface-to-surface during welding applications. These butt welding clamps provide the correct gap between panels to help produce clean welds that require minimal grinding after completion, making them an essential accessory for professional welders and fabricators working with sheet metal. The 4-piece clamp set is simple to use for assembling and fabricating tasks, proving ideal for welding patch repairs in floors, wings, door skins, or fabricating panels on reskinning projects. These versatile clamps accommodate flat, curved and pressed ribbed panels, providing reliable hold across a range of panel configurations commonly encountered in automotive and sheet metal fabrication work. To use the clamps, slacken the wing nut to allow space for the metal sheets to locate between the base of the clamp with the toggle bar underneath. Tighten the wing nut to pull the toggle bar up, locking the two sheets together side by side. Once the sections have been tack welded together, the wing nut can be slackened and the toggle bar removed, allowing the clamp to be lifted from the job prior to final welding. Features and Benefits: • Provides correct gap spacing for clean welds with minimal finishing • Simple toggle bar and wing nut mechanism for quick setup • Holds flat, curved and pressed ribbed panels securely • 4-piece set provides multiple clamping points for larger workpieces Specifications: Clamp Type: Sheet Metal Tools
