TIG waldi
Wannan walda ce wacce ba ta narkewa ba wacce ba ta da iskar gas mai kariya, wacce ke amfani da baka tsakanin injin tungsten da kayan aikin don narkar da karfe don samar da walda. Wutar lantarki tungsten baya narke yayin aikin walda kuma yana aiki azaman lantarki ne kawai. A lokaci guda kuma, ana ciyar da iskar argon a cikin bututun wutar lantarki don kariya. Hakanan yana yiwuwa a ƙara ƙara ƙarfe kamar yadda ake buƙata.
