I have been troubleshooting a problem with my welder... It's a Miller Syncrowave 250.... I have been having issues with the remote amperage control not working.... I have checked the potentiometer, wires etc. and found that I wasn't getting my 10 VDC for the potentiometer reference.... So I found a schematic and started checking components. (This problem has been intermittent and has finally quit working all together..) O.K I found the component that is bad.. It has a break in the casing I can put a little pressure on it and it will work. (I had already checked for a cracked etching and cold solder joint but all looked good...) My parts list says this is a RF Choke 250MA 3.8 ohms.... I can't seem to find anything listed this way? I really need to fix this thing I got some aluminum welding to do..
Thanks
