3. Bambanci tsakanin MIG da MAG yana cikin iskar kariya. Kayan aiki iri ɗaya ne, amma na farko ana kiyaye shi ta hanyar argon, wanda ya dace da walda ƙarfe mara ƙarfe; na karshen ne gaba ɗaya gauraye da carbon dioxide aiki gas a argon, kuma ya dace da walda high-ƙarfi karfe da high-alloy karfe.
4. TIG da MIG sune walƙiya mara kariya daga iskar gas, wanda akafi sani da walda ta argon. Gas din da ba shi da amfani zai iya zama argon ko helium, amma argon yana da arha, don haka ana amfani da shi sosai, don haka waldawar bakar iskar gas gaba daya ana kiransa argon arc waldi.
Kwatanta MIG waldi da TIG waldi
Kwatanta MIG waldi da TIG welding MIG waldi (narkewar inert gas garkuwar walda) a turance: walda ta ƙarfe inert-gas na amfani da narkakken lantarki.
