Then guess Have to do more better.

Looks like Ion drive in a way.

Very true

I think it depends on how much carbon is in the base metal (% of carbon) and how much carbon is in the filler metal. Welding a high carbon base metal with a low carbon filler metal will result in dilution of the weld bead and be it a full penetration butt weld, fillet weld, or a plug weld, a corresponding reduction of strength. It does not depend on the type of weld.....MIG vs stick but on the chemistry of the steel being joined.
Mild steel is a type of carbon steel. The element carbon is present in all steel. Whenever this carbon is the main alloying element, the alloy is considered a carbon steel. “Low-carbon” steel is another name for mild steel. There are other carbons steels, of different carbon contents.
Low carbon steel is typically the most readily welded steel in a room temperature environment. Examples of low carbon steel suitable for welding include C1008, C1018, A36, A1011 and A500. Medium carbon steel such as C1045 typically requires preheat and post-heat treatment to avoid weld cracking.
The major downside to mild steel is that it has a relatively low tensile strength, meaning it'll break more easily under tension than other steels. Luckily, there is a solution. Carburising is a heat treatment process in which either iron or steel is heated, with carbon liberated as it decomposes.
A lot of information you probably didn't know or want to know about welding low carbon aka "mild steel". How much carbon is in the particular steel being joined.....unless you have the certified matrtial test report or "heat number" for traceability...you will not know...but consider using a higher carbon filler metal to avoid dilution.....or..... just have at it and hope for the best.... just my opinion of course....

Great info was thinking a hi carbon ar500 to do it.

Dont think have to pre heat or any more than 60 to make this work.
