When the proper target is located, the electrode tip is briefly heated, carefully destroying the surrounding tissue to about the size of a pearl.
When the catheter is energized, the body conducts the energy from the catheter's tip, through the heart and to the electrode on the skin's surface, completing the circuit.
The tip of the tungsten electrode has to be hot in GTAW because you are trying to weld two pieces of metal together, and that takes a lot of heat.
Depend upon dia of electrode & Arc length between Electrode tip and job surface.
The tip of a tungsten electrode must be hot to facilitate the process of electron emission. When heated, tungsten atoms gain energy, allowing electrons to escape more easily from the surface, which is essential for maintaining a stable arc in welding or plasma cutting applications. This high temperature also helps to improve the electrode's longevity and performance by ensuring efficient ionization of the gas surrounding it.
Arc length is the distance from the tip of the electrode to the workpiece.
Positive polarity at the tip indicates that the tip of the electrode has a positive charge compared to the reference electrode. This is commonly used in applications such as electrophysiology, where a positive signal is measured relative to a ground or reference point to detect neuronal activity or other biological signals.
If the metal tip of a lead wire becomes detached from an electrode, it can result in a poor or lost connection, leading to faulty readings or loss of signal. This can impact the accuracy and reliability of the data being collected from the electrode. It is important to promptly replace or repair the lead wire to maintain proper functionality.
The calomel electrode is dipped into a KCl solution to replenish the potassium chloride at its surface and maintain a stable electrolyte environment. This helps to ensure the proper functioning of the electrode and accurate measurement of the potential.
tip of electrode has been lifted further away from work piece
Arc length is the maximum length between the tip of an electrode and the work, measured along the tangents.
The part of a neon stroke that ignites the gas is called the electrode or electrode tip. This is the point where the electrical current passes through, causing the gas inside the tube to ionize and emit light.
The electrode tip in an electric arc furnace (EAF) is typically made of graphite or a composite material. The composition can vary, but a common formula for graphite is C (carbon), often in conjunction with other additives to enhance properties like conductivity and wear resistance. The exact formulation may depend on specific operational requirements and the type of materials being melted.
