Modular two thyristor block for welding machines type A2Q Doppel Thyristor-Leistungsblöcke für Schweißgeräte, Typ A2Q

There is no technical problem with ignitron fuses exchange in welding machines. If we consider electrical connections, the thyristor connector needs only a system for thyristor triggering impulse conditioning. Conditioning systems is shown on diagram 1.
