Moderi nshya yo gusudira ya Heltec irakomeye cyane hamwe na max peak pulse power ya 42KW.Urashobora guhitamo impanuka ya 6000A kugeza 7000A.Byabugenewe cyane cyane byo gusudira umuringa, aluminium na nikel, urupapuro rwa SW02 rushyigikira umuringa mwinshi, nikel yera, nikel-aluminium nibindi byuma bisudira byoroshye kandi bikomeye (shyigikira nikel isize umuringa hamwe na nikel isukuye neza kuri batiri electrode yumuringa, umuringa usukuye urupapuro rudasanzwe rwo gusudira kuri bateri yumuringa electrode hamwe na flux).
HT-SW02H nayo irashobora gupima kurwanya.Irashobora gupima ubukana hagati yigice gihuza na electrode ya bateri nyuma yo gusudira ahantu.
