O'rta chastotaning nugget hajmini va lehim qo'shma kuchini ta'minlash uchunspotli payvandlash mashinasi, payvandlash vaqti va payvandlash oqimi ma'lum bir diapazonda bir-birini to'ldirishi mumkin. Muayyan kuchga ega bo'lgan lehim birikmasini olish uchun odatda quyidagi ikkita nuqtaga erishiladi.
Ya'ni, katta oqim va qisqa vaqt (qattiq standart deb ataladi) va kichik oqim va uzoq vaqt (yumshoq standart deb ataladi) ham ishlatilishi mumkin. Metallning materiali va qalinligi va ishlatiladigan payvandchining kuchiga qarab qattiq o'lchagich yoki yumshoq o'lchagichdan foydalaning. Spotli payvandlash mashinasi tomonidan metallni payvandlash uchun zarur bo'lgan oqim va vaqt mos yozuvlar nuqtasiga ega, uni ishlatishda qo'llanma sifatida foydalanish kerak. Payvandlash sifatini ta'minlash uchun spotli payvandlash mashinasi elektrodlarining ahamiyati odatda quyidagi fikrlarda aks etadi:
1. Oraliq chastotali spotli payvandlash mashinasining elektrod bosimi ikki elektrod orasidagi umumiy qarshilik R ga sezilarli ta'sir ko'rsatadi. Elektrod bosimi ortishi bilan R sezilarli darajada kamayadi. Shu tarzda, payvandlash oqimi faqat bir oz ortadi va ta'sir R ning kamayishi bilan bog'liq. Haddan tashqari issiqlik tufayli payvandlash issiqligi.
2. Payvandlash bosimining oshishi bilan lehim birikmalarining mustahkamligi doimo kamayadi. Yechim payvandlash bosimini oshirishdan iborat. Odatda, nuqtali payvandlash mashinasining elektrod so'nggi yuzining diametri doimiy bo'lganda, ishlov beriladigan qismning qarshiligi uning qarshiligiga bog'liq.
3. Yuqori qarshilikka ega boʻlgan metallar elektr oʻtkazuvchanligi (masalan, zanglamaydigan poʻlat), past qarshilikka ega boʻlgan metallar esa yaxshi elektr oʻtkazuvchanligiga ega (masalan, alyuminiy qotishmalari).
Shu tarzda, qarshilik nafaqat metallning turiga, balki metallning issiqlik bilan ishlov berish holatiga, ishlov berish usuliga va haroratiga ham bog'liq. Bunday elektrod bosimi ikki elektrod orasidagi umumiy qarshilik R ga sezilarli ta'sir ko'rsatadi. Elektrod bosimi ortishi bilan R sezilarli darajada kamayadi, ammo payvandlash oqimining o'sishi katta emas. R ning pasayishi natijasida yuzaga keladigan qarshilikka ta'sir qila olmaydi. Issiqlik ishlab chiqarish kamayadi. Shuning uchun, o'rta chastotali nuqta payvandlash mashinalarida payvandlash bo'g'inlarining mustahkamligi har doim payvandlash bosimining oshishi bilan kamayadi. Yechim payvandlash bosimini oshirishda payvandlash oqimini oshirishdir.
