You can try Lawson https://www.lawsonproducts.com/Certanium/889-Cast-Iron-Stick-Rod-Electrode-532/P12006.lp There are other brands that are high nickel content. The certanium seem to flow real well, but pricey. Good deal on ebay for nickel rods https://www.ebay.com/itm/294318845754?hash=item4486c52f3a:g:GCEAAOSwxZRhDY2H
