These special welding clamps are used to weld metal sheets of unequal thickness (e.g. 0.8 mm against 1 mm) edge-to-edge. With the 2 adjustment screws on the clamps, you can ensure that you do not see a difference in thickness on one side (top or bottom).
These edge-to-edge welding clips are an absolute must for perfectly aligning sheet metal before welding together.
These clamps leave a space of 1 mm between the sheet metal to be welded. They can be used for both straight and curved panels. Easy to install and remove.
