hi guys
This is my second post on this dam welder please forgive my ignorance however i hope with the aid of some photographs and your technical expertise to finally fix this machine The bremas 6 position ( including off ) switch packed in and my friend who owns it decided to commit the ultimate sin of stripping it down and reassembling it incorrectly .a few very helpful members on this forum sent me a drawing and advice stating i only need a 6 way single pole switch .
i wrongly titled my previous post supermig 250/10 so eddie very kindly sent me a drawing for that machine however i think this is an earlier model . i have today spoken to sealey who sent me a manual for the supermig 250 hopefully attached and you guessed it its different in that if you look at the drawing there are 6 power setting etc . etc
The old bremas switch also switched the neutral therefore i ordered a suitable rotary switch be it with 6 positions .
looking at the transformer bobbin you can see five tappings i assumed the bottom tapping to be the neutral as one wire goes to the bottom of the contactor which i was informed gets switched
.I also assume the yellow wire top of the bobbin is the first tapping ? however if that is the case, that only leaves three more tappings ( if the bottom one is neutral ) .so how does it have five power settings? . there is also another two yellow cables which go from the other side of the transformer to the pcb via a multi plug . The bottom bobbin has two cables as i said one going to the contactor the other going to the switch hence my reasoning for it to be neutral .
when my friend reassembled the switch he said it was not performing correctly could he of damaged anything silly question i know but likely candidates ?
I have tried measuring resistances but my cheap meter wont read them what sort of reading should i get ? . on the bobbins the cables get progessively thicker the lower down you go hence my assumption of higher power setting .
sorry for any confusion i know for you guys who work on these machines regularly its probably simple but when you have a switch reconfigured incorrectly and cannot source a correct drawing it does get a little confusioning any help will be very greatfully recieved .thankyou
