1. Manual metal arc electrodes are not designed for use as filler wire in TIG welding. They are typically used for shielded metal arc welding (SMAW) and have a different composition and flux coating that is not suitable for TIG welding.
2. Using stripped electrodes as filler wire can result in poor weld quality, lack of fusion, and potential defects in the weld joint. The flux coating on the electrode is designed to protect the weld pool and provide a stable arc, which is essential for producing high-quality welds.
3. Stripping the flux coating off the electrodes can also introduce impurities and contaminants into the weld, leading to weakened mechanical properties and potential failure of the weld joint.
4. It is important to use the correct filler wire for TIG welding, which is typically a bare or lightly coated wire that matches the base metal being welded. Using improper filler wire can compromise the integrity of the weld and result in costly repairs or rework.

Using bare manual metal arc electrodes as filler wire for TIG welding is not advisable due to the following reasons:
- Contamination: Manual metal arc (MMA) electrodes are typically coated with a flux that protects the weld pool from atmospheric contamination. When these electrodes are used without the flux, the weld pool is exposed to oxygen and nitrogen, which can lead to weld defects such as porosity, cracks, and reduced strength.
- Arc Stability: The flux on MMA electrodes also helps stabilize the arc. Without the flux, the arc can become unstable, making it difficult to control the weld pool and resulting in inconsistent weld quality.
- Filler Wire Properties: MMA electrodes are designed specifically for arc welding, and their composition and mechanical properties may not be suitable for TIG welding. Using them as filler wire can result in welds that do not meet the required specifications.
Therefore, it is important to use proper TIG welding filler wire that is specifically designed for the application to ensure the quality and integrity of the weld.
