The electrode arm is an important part of welding equipment.

The main function of the electrode arm is to hold and position the welding electrode. It provides a stable and adjustable support for the electrode, allowing it to be accurately placed on the workpiece for welding. The electrode arm also conducts electricity from the power source to the electrode, enabling the welding current to flow and create the weld.

Electrode arms are widely used in various welding applications, including:

• Arc welding: In arc welding processes such as shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux-cored arc welding (FCAW), electrode arms are essential for holding the electrode and conducting the welding current.
• Resistance welding: In resistance welding, electrode arms apply pressure to the workpieces and conduct electricity to create the weld.
• Spot welding: Electrode arms are used in spot welding to hold the electrodes and ensure proper alignment and pressure on the workpieces.
