Jack,

I recently welded a steering bracket on an M and a another small front end piece on an A. Those were my first attempts at cast stick welding (I spend most of my welding time using a pulsed MIG machine), but they seem to have worked just dandy.

I know there are a couple of schools of thought on how to weld cast, i.e. preheat or not, but I elected not to preheat. There wasn't a good theoretical reason behind this...it was mostly because I don't have a oxyaxl setup and I couldn't get away with baking the part in the kitchen oven ;-). In any case, I took it nice and slow...laid down about 3/4" of bead, then I went off and did something else for 5 or 10 minutes. Came back, laid another 3/4" of bead as far away from the previous one as possible, and so on. Just tried to keep the part as cool as possible.

Also, when I bought my cast rod, the welding shop guys suggested a more spendy rod...it's UTP Econocast 99. I'm using 1/8" rod, and I got 1 lb. (about 20 sticks) for something like $30. Since it's the only one I've used, I can't compare it, but it seems to have worked well.

Finally, here's a link to an article by Lincoln Electric I've found useful.

Have fun, and feel free to ping me for pics or anything else that might be helpful.
