Timco AC/DC TIG Electrode, color code WC20=GRAY, intended for all metals. Good ignition properties.
This electrode contains Cerium oxide (CeO2). This electrode is used for both alternating current (AC) welding and direct current (DC) welding. The durability of these electrodes is somewhat better than that of pure tungsten electrodes. Mainly used for welding unalloyed and high-alloyed steel, aluminum, titanium, nickel, copper and magnesium alloys at low and medium currents. Suitable for practically all metals.
- Delivery includes 10 electrodes
- Diameter: 1.6 mm
- Length: 150 mm
- Packed in a convenient storage box
- Color code: Grey
- Application: All metals
- Welding method: AC/DC (alternating current/direct current)
Since different TIG electrodes all have their own good properties, choosing the right electrode is important.
