Hi , I have a dead tig welder and I would like to salvage the transformers and the IGBT from it, I have found a similar idea on the net But they are not descriptive enough on what is what. I need to know how to make the igbt work and also how does the large current get through the IGBT. All this is new to me I did not know what an IGBT was last week so I am trying to learn what is a totally new technology to ME. PLease please please, can anyone supply a block diagram of a basic TIG inverter and a brief description of what is happening at each block in the diagram.
I dont understand what the inverter is doing and how does it give me my square wave 150amp welding current.
Thank you.
