Thepa ea 'mele: phofo e putsoa e bobebe e nang le sebaka se setle sa ho qhibiliha le ho hanyetsa ho bola.
Tšebeliso e ka sehloohong: e sebelisoa e le tlatsetso bakeng sa li-alloys le tlhahiso ea li-electrode tsa welding, refractories, joalo-joalo.
Ho paka: Ho paka botlolo ea polasetiki ka lebokoseng le ka ntle.
Ngola molaetsa wa hao mona mme o re romele wona
