summer is here, plant a tree. if you don't have space or time to plant one sponsor some one else to plant one for you. a tree is an investment in our planet, help it out.

Need more info
If you are using horizontal to mean "in position" and in the flat, like a 2F weld, then electrode angle is 1/2 of joint included angle, and electrode inclination is 5 to 30 degrees (I stay almost upright) pointed in the opposite direction of travel and you use a straight backhand or drag technique with no whip required.
If you are using horizontal to mean a horizontal seam on a vertical surface, like a 2G, then elecrode angle is still 1/2 of joint included angle (slightly modified to counteract gravity on the weld) and electrode inclination is still the same backhand drag technique. Instead of pointing electrode into seam at 90 degrees to work, angle slightly (5 or so degrees) upwards to counteract gravity causing the puddle to sagout. Also as you progress with the weld, try using a slight saw motion ^^^^^^^^^^^^ to help with sagout and metal deposition.
*** Pay close attention to your electrode inclination in the second example, if you angle the electrode too sharply upwards, you will create a "long arc" situation above the electrode which will make the weld deposit very hot and hard to control, and the puddle will get away from you and drop on the floor.
All the advice I can give you for now. Not sure if it answers your question, but I hope it helps. I'm not sure when I will get to a computer next - I'm on holidays in PEI.
