22.2 Ignition transformer ZM 20 / 10 (2-pole)
22.2.1 Description
The 2-pole ignition transformer is earthed at the centre point of the secondary development. The transform-
er ignites electrode against electrode; ignition from one electrode to mass must not occur. The 2-pole igni-
tion transformer generates less radio interference levels.
