Welding different thickness metals together

Would someone give a little advice on welding two different thickness metals together. Specifically, I'm fillet (I think that's what it's called) welding a piece of 16ga sheet metal to a piece of angle iron (a little over 1/8"). I know I need enough penetration into the angle to make a good weld but am concerned I'll just burn through the sheet metal.

Thanks in advance for your help.

Hold your arc on the angle iron and watch as the puddle flows into the sheet metal. You can control the heat this way and pull back if you see the thinner metal starting to get too hot. Good luck.

You can try what majakdragon suggested and if you run the bead in a "C" motion, you can control the heat on the thin piece by moving slightly faster while near it.
