    Assuming it's 4130 I would use er70 tig wire.

    If you do a search on here you will get more reading than you want.

    edit -- I removed "er80" from my above sentence.

    ER80 filler is closer to the strength of the 4130 than ER70 if you're not planning on heat treating the part after welding. Do a little research on welding 4130 before you do the job because you can mess up the material by getting it to hot or allowing it to cool to quickly.
