increasing drivers tech.

[Serger]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:
Electrical Arc
Before making electrical arc welding on the machine, cease working of the batteries and alternator for the safety of the circuits and parts.
The battery should be ceased even if the battery isolator is assembled.
Pay attention to allow the ground return line to be shorter as much as possible. In this way, it will be prevented to give high voltage into the chassis or cable mechanism of the machine.
If the INCREASING DRIVERS and electronic control units (E.C.U.) are plugged in the machine, they must be pulled out before starting welding. If the increasing drivers and electronic control units (E.C.U.) are not pulled out, irreparable damages may occur at the electronic components.

Заранее спасибо

Судя по "Pay attention to allow the ground return line to be shorter as much as possible"
текст не весьма грамотный со всех сторон

поэтому ввиду своей полной технической безграмотность предполагаю, что имеется в виду

усилитель чего-то

какие-нибудь повышающие преобразователи
