What is the purpose of an electrode holder?

The purpose of an electrode holder is specifically to securely hold the electrode during welding while also ensuring that there is a reliable electrical contact between the electrode and the welding circuit. This component is essential as it allows the welder to maneuver the electrode with precision while maintaining the continuity of the electrical connection.

A good electrode holder is designed to withstand high temperatures and should insulate against electrical shock, providing safety to the welder. It is crucial for the holder to be robust, allowing it to accommodate different sizes and types of electrodes, thus enabling the use of various welding methods.

The remaining options describe functions that are not directly related to the primary role of the electrode holder. Adjusting the arc intensity, controlling welding speed, or cooling the weld area involve different tools or techniques, such as adjusting the power settings on the welding machine or using a cooling system, rather than the electrode holder itself.
