There is a marking substance made by curv-o-mark not sure what its called but it actualy ignites when in contact with the arc. It is very usefull when it is hard to see the weld path. It gives you a very good indecator as you move along centering you on the weld.

Welding axle is complete. I bought Ni lincoln rod but it would not run worth a shit. I ended up welding it with 7018 an inch ir so at a time and jumping around quite a bit. It welded very nicely and with no cracking. I preheated at 350 and post heated down to room temp over 24 hours. Seems they may ...

I too responded to the first page and this page did not pop up until I replied. Good to see you found what you needed.

I agree with alot of whats been said. I started welding on a farm at fourteen and spent four years learning by mistakes and mentors. At 18 I went to vocational school and learned alot of the fundamentals on set up, speeds and metalergy. The classes would have baflled me and I would not have "co...

roger, I know these can go either way. I have done alot of cast welding but not recently and its good to refresh yourself with the knowledge of others. Two more questions while I have you. Is the Ni (nickel rod) from lincoln or whomever a weaker filler? I was planning on putting the whole axle in my...

thats another thing, the nuckles are pressed on so I cannot preheat them without warming the axle tubes, do you think that will be a problem? I was tacking evering thing in position with a 70XX wire and the tacks were cracking so I know it will not work well. I have seen alot of motor heads get away...

Forgot to ask: Lincoln had broblems with NR211 being brittle and came out with NR212, which is a more ductile filler. Anyone had experience with using this on cast?

? I am working on rotating the steering nuckles on a dana 60. I have some high content nickel rod from lincoln that has worked well for me on cast. I have a good bit of build up to do in some areas and would prefure to run wire feed. Is anyone familiar with this process, and if so could you recomend...
