A ground clamp, also called an earth clamp, connects the welding machine's return cable to the workpiece. A firm connection gives a stable arc and cleaner welds.
How to choose a ground clamp
- Current rating: 300A clamps suit light and TIG welding machines. 500A clamps suit heavier stick and MIG work. Match or exceed your machine's output.
- Spring or magnetic: spring clamps grip edges and tables. Magnetic clamps hold onto flat steel surfaces where a jaw won't fit.
- Jaw contact: copper or brass contacts and a strong spring keep resistance low and stop the clamp from heating up.
