A benefit of transferred DC torches is that the plasma arc is formed outside the water-cooled body, preventing heat loss—as is the case with non-transferred torches, where their electrical-to-thermal efficiency can be as low as 50%, but the hot water can itself be utilized.
Keuntungan obor DC transferred adalah busur plasma terbentuk di luar badan berpendingin air, mencegah kehilangan panas — sebagai pembanding obor non-transferred, di mana efisiensi elektrik ke thermal bisa jatuh 50%, tetapi air panasnya itu sendiri dapat dimanfaatkan.
