1、LARGE SUCTION WITHOUT FALLING OFF: Ground clamp has large suction surface, not falling off, possess stable magnetic force and not degaussing, very stable 2、WITH RUN ON TAB: The upgraded type has a run on tab, which can be tried at any time during use. The positive and negative poles are directly connected by wires to see if there is current passing through 3、BETTER CONDUCTIVITY: The conductive effect is strengthened, the fire is fast, the use is durable, and the operation is convenient 4、SAFE BRASS NOSE: Grounding magnet connector come with thickened brass nose for secure wiring entry, you can use with confidence 5、STRONG ADSORPTION: The magnet and the conductive rod shorten the distance to prevent warping, and the adsorption is stronger and the workpiece is attached
