May I ask at what amperage setting you are welding and what type of rod you are using. It looks to me like you are much to cold, at the right temperature using a 7018 (CSA 4918) rod and welding in the flat position it should pretty much weld itself. If you have an amperage gauge on your machine here is a list of starting points for welding.
3/32 7018 80-110amps start around 90
1/8 7018 110-140 amps start around 125
5/32 7018 150-190 amps start around 165
I wouldn't use a rod much bigger than those, if you don't have a gauge you can set your heat by taking a piece of scrap steel, set your heat and fire in, pull a bit of an arc and let your puddle establish, slowly lower your rod point if it snuffs out you are to cold.
Go up 5 amps and try again, when you can drive the rod into the puddle without it snuffing out you are at the right temp, with enough practice and a machine with an arc force setting I can drive a 1/8 7018 through a 1/4 piece of steel no problem.
If you have any questions on welding or proper techniques don't be afraid to PM me, I'm new to the forum but I'm a welder by trade and can weld anything from the crack of dawn, to the crack of your butt :D
