What is the large wire that runs from the welding machine to the electrode holder called?

Explanation:
The large wire from the welding machine to the electrode holder is the electrode lead. It carries the welding current from the power source to the electrode, allowing the arc to form as the electrode meets the workpiece. The circuit is completed back to the machine through the ground lead, which is the separate heavy conductor connected to the work clamp. The shielding gas hose provides shielding gas (in MIG/TIG setups), not current, and the control cable carries remote controls or settings rather than the main welding current.
