Shunt Coil Shimming

go to see Welding Machine for Shunt Coil Shimming

So, I've purchased SA 200 (code 9325). Found it had a bad shunt 6°Clock. After installing new set, I notice some play on both shunts. Has any one done shimming on shunt coils or do I have the wrong ones.?Short video clips of play:https://drive.google.com/file/d/1XiO...w?usp=drivesdkhttps://drive.google.com/file/d/1XpO...w?usp=drivesdkLast edited by Mr.Ar0n; 04-26-2020 at 06:38 PM.    Currently working on:    1966 Lincoln SA 200 Redface    19??

Replyang, I've never seen shunt coils that loose. Where did you get the replacements from? Hmmm...I wonder if those being that loose would effect the voltage output.SA 200s : 1944 1945 1963 1965 1969 1981 SA 250 D3.152 DC only2004 Ranger 10,000Lincoln Pro Mig 135Miller Load BankHobart GPB 258 PipelinerHobart GPB 261 MainlinerHobart Airforce 250Everlast PA 200st
Reply:They are hybriweld shunt coils.. I called them and spoke to the technician/mechanic, he basically told me that it happens from time to time. Recommended to use wood shims to secure them and once machine was running that coils would magnetize and stay in place.I used some muffler gasket material from local O'Reillys (.060" thick) to shim all the way around shunts and pressed shunts using old shunt coil as a dampner. Worked out great..    Currently working on:    1966 Lincoln SA 200 Redface    19?? Lincoln SA 200 Green Light
