MMA holder change

[Memmeddu]

You dont solder welding cable you crimp the end on, heat shrink is a non starter as it is an insulater.
Grease should never be used because of the heat of rod holders will melt or ignite it. You clean the threads with a wire brush and remove all the detritus.

Our Kings are simple, pull the handle down, take a ferrule and measure the length and strip the end of the cable to that length, fit the ferrule and crimp, slide the rod holder handle over the cable and push the ferrule into the top with the V of the crimp aligned with the screws, tighten 8MM studs with an allen key and fit the seal, slide the handle back up and push the locking pin back in.

No exposed cable.

There is special grease for electrical contacts and you don't have to put a big amount , just little bit to prevent the screw to seize up .
Soldering the wire on a lug terminal instead of crimping (do you have a 50mm² crimper?) Because it's easier.
Heat shrink tubing to limit corrosion on the joint and keep everything nice and clean .
I have two styles of holders .
One uses the ferrule as you said and 2 Allen screws
The others use a lug terminal as same as ground clamps

In the case of the ferrule there is no need for soldering but you still can put heat shrink to cover 2 cm of the brass body of the holder and 10 cm of your cable.
Providing protection from the air and preventing the cable to move sideways in the joint breaking the strands .

Years ago .when I changed my buzz box & leads over to a dinse set up with a commercial cable size plus the black & yellow 600 (?) amp electrode holder I had to turn some brass rod into a tube using my drill press & anneal it to get the ferrule for the electrode holder as nobody seemed to hold them in stock locally & I couldn't find them on eBay .

one old guy I worked with many years ago used copper pipe, he slit them lengthways and slid one inside the other until he had approximately the correct inside and outside diameters and used them.

Did that recently with the old buzz-box at my Men's Shed. It's working perfectly.
