Ok, I am not much of a welder but bought an old Miller stick welder a week ago. I see them around about every farm and I now have a need for it - I broke the leveling arm off my 3 point on Ford 3000 and would like to weld it back together. So, which electrode should I purchase for a general, all around steel rod. Nothing fancy, not stainless - what is a most common welding electrode that I should try welding with. I ran a few beads about 20 years ago but haven't touched a welder since......

I would guess the arm is cast steel. Better take it to someone that knows what they are doing on that one.

Yup, if it.s cast, take it to a pro.


For mild steel, E6011 penetrates deeper and solidifies faster. E6013 Fills faster. Both are general 'all purpose' all position rods.

Are they the best? NO, but depending on the particular model of welder you have it might not perform well with more specialized rods.

If it has DC capability, E7018 or E7014 would be great choices.

You can buy cast rods, grind the corners off, then burn deep inside, weld an inch or less and peen the heck out of it to relieve heat stress

the exterior is cast but threaded bolt where the break is - is steel - has been welded before but did not penetrate through. I am at no loss if I cant get it to weld - I just want to be able to try and fix it myself. I have already ordered another new one and broken it as well and sent it back......I just want to work on my welding ability and this arm is a good project to start on - I did read that E6013 is pretty common.

what chas said and

get several pieces of scrap steel together and run test beads first no ones first bead looks good and you need to adjust your amperage and find what the rod likes.


America only has one issue, we have a Responsibility crisis and everything else stems from it.

Probably Low/Medium Alloy Cast Steel. You'll need to lookup preheat temp and maximum interpass temp. Get an ir thermometer so you can watch the temp. Cast steel isn't as prone to cracking like cast iron but it will still warp real bad. Cover it with some sand to let it cool if you can. Use 7018 DC if you have it or get the AC rod if you don't.

If your wanting to practice i would pick up some of diff rods ,welding your cast go for the nickel 99 rods , 1/8 6011 on most steels and Lincoln has a very nice 7018 ac rod. i would look deeply into my breaking problem. o and my opinion go Lincoln all the way.

logger coffey, his parts are likely cast steel not cast iron. I know you can use Nickle 99 on carbon steels too but I think it's pretty soft for milling and drilling not stressed areas.

I don't think I would try to learn to weld by starting with anything cast.

Don't let the word cast scare you. Cast iron is difficult to weld but cast steel is not. Just got to pre heat, cool slowly and use the right rod.
