u'amea maualuga kaponi va'a uaea uelo F7A/P4-ECG ma uelo fe'avea'i uelo fau fa'atasiga
Faʻaaogaina mo le -60C aʻafiaga manaʻomia siosiomaga, e masani ona faʻaaogaina mo le fausiaina o vaʻa, paipa, vaʻa faʻamalosi.
O a uiga fa'apitoa?
●O le u'amea pa'u u'amea i lalo uaea uelo arc o le 480MPa vasega maualuga malosi ua ueloina i le GXL-121 flux. O le arc combustion e mautu, o le aveesea o slag e faigofie, ma o le uelo pasi faia e matagofie.
●O le u'amea u'amea o lo'o i ai mea fa'ainisinia sili ona lelei, maualalo mea o lo'o i totonu o le P ma le S, ma sili atu ona lelei le fa'atinoina o le aafiaga o le vevela.
