Hello,

I am currently in the process of restoring a Lincoln electric Ranger GTX 250. The welder generates power no issue and welds in AC mode only. after doing some investigation, and asking the previous owner, he stated the terminals for the choke coil had corroded off and instead of getting into repair, he decided to purchase a new welder. the machine has seen a lot of road salt & elements in its life. and as a result, the terminals for the choke coil inside the front cover area have corroded off. as a new coil is about $900:( I would be curious to try and repair the coil before pulling the trigger on a new one. however I cannot seem to find where the terminals were previously affixed on the coil itself, and all results I can find online do not show where the actual terminals on the coil itself are/connect to:confused:. if anyone has a similar machine with aforementioned coil and would be able to take a photo or show where the terminals attach, it would be greatly appreciated . photo attached of corroded terminals. machine code is 11400 if it helps.
thanks:)

Removed the choke coil. I can see where the terminals at one point were. they are corroded off too far to be able to solder directly onto the end of them(see photos). so I traced them back and just cut the winding at the closest point to where they terminate if that makes sense. if the repair does not work, then I didn't loose anything. should it work, I save some money. attached are photos detailing it. I will solder connections and reinstall. I will keep the thread updated after I try it to see if it works. :) coil also still has continuity from one terminal to the other

If the soldering doesn't work out , drill a 1/4 " hole and use a ring treminal & wire , shortening the windings like you're doing will have no noticeable effect , you should be good to go .

ps - now is a good time to put some paint on the iron core and " gussy " it up ....
