Abstract
A clamping device utilizing the principle of leverage comprises a body, a L-shape front clamping leg, a pair of L-shape rear clamping legs, a spring clip, and a braided ground wire. Both the front and the rear clamping legs are slidable on the body and fixed by wing screws so that the position of the body relative to the front and rear clamping legs is adjustable and hence the clamping size and clamping force are also adjustable. Copper tips are added to the legs to eliminate sparkling while welding. A braided wire can be connected to the body for grounding purpose.
