Timco AC/DC TIG Electrode, color code WL20=BLUE, intended for all metals and micro plasma induction. Good ignition properties. Lanthanum-alloyed electrodes are suitable for direct current (DC) and alternating current (AC) welding. They are mainly used for welding unalloyed and high-alloyed steels, aluminum, titanium, nickel, copper and magnesium alloys. Blue electrodes are also suitable for micro plasma welding.
- Delivery includes 10 electrodes
- Diameter: 2.4 mm
- Length: 175 mm
- Packed in a convenient storage box
- Color code: Blue
- Welding method: AC/DC (alternating current/direct current)
Since different TIG electrodes all have their own good properties, choosing the right electrode is important.
