Lightbulb Where do I start.

I haven't welded since 1968 when I was in metal shop in high school.
I own a Dayton ac/dc electric welder.
For my first project I want to weld 1/8" x 2" x 2" angle iron to a 1/4" mild steel plate.
1.Should I use ac or dc.
2.What would be the best settings.
3.What would be the best rod to use.
4.Is there a book that would give me this type of info for various metal projects.

Thank You,
Pat

for 1/8 inch plate, i'd use a 3/32 or 1/8 E7018 or E6013 rod on DC current. maybe set the amperage at 90-100? If you haven't welded in a while, i suggest that you run a few practice beads before you start your project. I could be wrong on the settings, its been a while since i've used stick too.

Clean all the metal where the weld will go with an abrasive wheel or wire wheel.
For starters, 1/8" 6013 - available nearly everywhere - at about 100-110 amps DCEP.
Aim the electrode more toward the 1/4" plate and less toward the 1/8" angle to avoid burning holes in the angle. Start at the corner of the angle iron and drag it back toward you with just a bit of weave to make sure that the puddle connects both pieces of metal. At the end, point the electrode straight down to the 1/4" plate before breaking the arc to avoid burning off the outer end of the 1/8" material. Otherwise, all that heat will burn back the 1/8" material at its thinnest point. Remember to watch the puddle. 6013 is a contact rod, so you can let the flux cover drag on the metal with less chance of sticking. With electrodes such as 6011 and 7018, a short arc rather than contact is required.
