Hello , my high frequency transformer burned out on this welding machine butters (NBC) Auto tig 160 ac/dc, can you help me with an electrical diagram, or with information where I could purchase another part of the same or equivalent? Thanks
That ferrite-cored transformer looks like a line-output transformer ( LOPT ) or flyback transformer from a television. They were used to provide the high voltage for the anode of the CRT tube. Description:
I have a Hobart Cybertig 300 S, square wave tig welder probably from the 80's. The high frequency quit working so I took the covers off the side to take a look at the spark gap. The gap was fine so I started taking a look at the rest of the circuit. What I found was that the primary side coil...
