Wood furnace repair

What welding projects are you working on? Are you proud of something you built?
How about posting some pics so other welders can get some ideas?

So, I'll try and post some pics of the cracks.

This is a USSC 1300 hotblast.

Pretty basic stove. Plate steel. Got some cracks. Planning on grinding out and drilling.

Question I have is what process not to use. I really don't think this is a big deal. I am thinking just using mug or stick.

I realize some are going to say that I'll burn my shop down but right now I don't have the funds to buy a new one with and I really don't want to what with all the EPA crap and regs and all...so, just gonna fix this one.

Is there a filler wire or electrode that would be better than others without getting too fancy?

7018 stick. That would be my choice. If it were a code repair I'd tell you to use a 200F preheat.
I have more questions than answers

7018 would be my choice too. Although I would preheat just to make sure it never cracked again. No need to heat to a certain temp as its not critical, but just enough to get her good and toasty should be enough. I would drill a hole at the ends of the crack though. Then Weld.
