Frekwenza intermedjamagna tal-iwweldjar fuq il-postelettrodi ġeneralment jużaw ram tal-kromju taż-żirkonju, jew bronż tal-berillju, jew ram tal-kobalt tal-berillju. Xi utenti jużaw ukoll ram aħmar għall-iwweldjar, iżda biss f'lottijiet żgħar.
Peress li l-elettrodi tal-welders fuq il-post huma suxxettibbli għas-sħana u jilbsu wara li jaħdmu għal żmien twil, li jirriżultaw f'reżistenza interna ta 'kuntatt miżjuda u kurrent imnaqqas, għalhekk għandhom jintgħażlu materjali tal-elettrodi xierqa. Elettrodi differenti jintużaw biex iwweldjaw materjali differenti. Per eżempju, meta l-iwweldjar tar-ram, għandhom jintużaw elettrodi tat-tungstenu.
Elettrodi tar-ram tal-kromju jistgħu jintużaw b'elettrodi tal-vireg tat-tungstenu pur inkorporati fin-nofs. Ġeneralment, liga tar-ram imsaħħa bit-tixrid (Al2O3-Cu) tintuża direttament, u l-ħajja tas-servizz tagħha hija 5-10 darbiet dik tar-ram tal-kromju. L-ebusija tat-tungstenu pur hija relattivament fqira. Jekk ma tistax issir fiċ-Ċina, ġeneralment tiġi ttrattata b'nitroġenu likwidu.
Tevita l-fenomenu tat-twaħħil tal-elettrodu, il-parti tal-iwweldjar ma ssirx isfar, il-ġonot tal-istann huma sbieħ, konduttività elettrika eċċellenti u konduttività termali, prestazzjoni tajba ta 'temperatura għolja, u l-elettrodu tar-ram tal-alumina jista' jkollu rwol akbar meta kkombinat mat-tħin tal-elettrodu funzjoni tal-welder fuq il-post ta 'frekwenza medja.
