KOVET- WT20 is thoriated type tungsten with addition of 1.80-2.2% Thorium oxide content for TIG welding process. It is easy arc starting, higher current capacity and good arc stability for DC welding. It can be well operated even when overload with extra amperage, thus improves the performance of welding. It is best for welding of copper alloys, nickel alloys, titanium alloys, aluminum alloys, stainless steels and non-corroding steels.
