HOW2 weldup crack in a Jotul [castiron] wood stove ?

Just got a Jotul Model 118 that has a large crack on one side and a small one on the other side.
What's the best way to weldup this crack that will be durable given that
it's a cast iron wood stove ?
Also it's missing the two side baffles. Any suggestions for fabricating something adequate will also be appreciated.
Cordially, Courtney

Jotul stoves are really nice. My parents had one in a summer cottage in Michigan. Amazing how much heat such a small stove could produce.
The best method would be to have it welded up by a shop that rebuilds heavy diesel engine blocks and heads. They wil preheat it to bright red and gas weld it with cast iron rod.
Might be expensive, or they may cut you a deal for such a simple job.
The more common way to repair it would be to gas braze it or stick weld it using a high nickle filler rod.

RE: the nickel rod, should it be Ni + Cu, or, Ni + Fe ?
What is gained/lost from each ? Is it that the Cu rod results are more ductile and the Fe combo is stronger, or what ?
Appreciatively, Courtney

I think a Ni+Fe rod would be better for this.
UTP Econocast 55 and 75 work very well.

Sorry but I also meant to ask,....
Is the stove gray metal and if not, what then ?
Gratefully, Courtney

It is most likely gray cast iron as they are completely annealed.

On the side baffles, youy should try to find some cast iron chunks from an old bathtub to weld in place.
A plasma cutter or abrasive wheel will cut cast iron.
