Grey tungsten is known for its excellent ignition properties, meaning it starts an arc easily even at low amperages. It is a favorite for orbital tube and pipe welding, thin sheet metal work, and delicate parts where precision is key.
| Feature / Material | Compatibility | Why it works |
| DC (Steel/Stainless) | ⭐⭐⭐⭐⭐ (Excellent) | Maintains a sharp point; very stable arc at all power levels. |
| AC (Aluminum/Magnesium) | ⭐⭐⭐⭐⭐ (Excellent) | Handles high current better than Pure tungsten; holds shape well. |
| Arc Starting | ⭐⭐⭐⭐⭐ (Excellent) | Low "work function" allows the arc to jump easily without sticking. |
| Service Life | ⭐⭐⭐⭐ (High) | High resistance to thermal shock and erosion. |
| Inverter Power Sources | ⭐⭐⭐⭐⭐ (Optimal) | Specifically engineered to work with modern high-frequency inverters. |
| Electrode Diameter | DCEN (Direct Current) | AC (Alternating Current) |
