Wt-20 (red) -Contains thorium oxide.

These are the most common electrodes as they first showed significant advantages of compositional electrodes over pure tungsten when welded on a constant current.

However, thorium is a low level radioactive element, so the dust that is inevitable when sharpening can be harmful to the health of the welder and unsafe to the environment. If they are not used so often, minor discharge will not cause any damage to health. But if it is planned to constantly work with such electrodes, it is necessary to equip the place with a good ventilation system.

Torated electrodes work well when welded on a constant current and with improved current sources, and depending on the task you can change the angle of the electrode. They perfectly retain their shape even on large currents, unlike pure tungsten electrodes that begin to melt.

Unlike previous electrodes, this type does not need to give a spherical shape when welding with variable current end-it is enough to make a very small bulge. However, it should be noted that in this case, the welding arc will jump over the protruding surfaces, causing the so-called "fermentation". Therefore, wt-20 is not recommended for welding on variable current.

Main welded metals: Stainless steel, high melting point metals (molybdenum, tantalum), niobium, and its alloys, copper, and bronze, are all available.
