Big Mouth Pliers Pliers w/ Copper Grounding

Entry level for a good weld is a good ground these are definitely not as quick as a spring clamp but the surface area and build quality and confidence of your ground is all right here. Highly recommend

Grounding clamp

My favorite clamp. Easily adjusts for different thicknesses on table and work piece.

Nice product, easy to adjust and quick to utilize. Seems robust.
