Stahlwerk TIG 200 Cod Integrat

Buna ziua! Am un aparat de sudura Stahlwerk TIG 200 DC Pulse ST IGBT, modelul mai vechi din 2019 nu cel actual. Problema pe care o am cu el este ca nu raspunde la comenzi, l-am desfacut si am observat un integrat defect dar pe care nu se intelege seria acestuia, ce se vede pe el este LM3 SBKQ. Are cineva un aparat la fel care ma poate ajuta cu un cod sau cum sa identific integratul? Tin sa mentionez ca nu sunt electronist, am fost cu aparatul la un electronist care a spus ca inafara de integrat nu are nicio problema.

 Am atasat cateva poze cu integratul si seria placii.
