Aspiring TIG welders very quickly learn the importance of good tungsten electrode grinding skills. All it takes is a moment’s distraction or a tiny tremor in the torch hand to plunge the ...
It’s right in the name. TIG welding uses sintered tungsten electrodes; rare earth oxides reduce the work factor to make striking arcs easier. Source: Adobe Stock. Another important industrial ...
