Do you mean pulling by back stepping? Is that the same thing? I haven't tried pushing yet but am familiar with that technique. I'm using .30 solid wire. Unless i'm totally an idiot and have been using flux wire. It's just the wire that came with the welder, it's a hobart HB-28. I tried finding that wire to get some specs on hobart website and couldn't find any information. I have read/heard about this wire on other websites and guys have said that it's a pretty good wire though. Did not hear anything about it being a flux core wire though. Maybe i'm wrong though. That would be an easy fix. I've tried the recommended voltage and speed for 1/8" thinkness wire recommended by Miller on the charts that came with the welder. I don't know what the numbers you are referring to of WPS=165 and Volts=17.0. Is there a calculation for that?
Thanks in advance for all the input. Hopefully I can figure this out soon so I can make my Jeep a better rig.

You can drag a weld puddle with wire feed, just make sure you have a good travel angle in front of the weld puddle. Pushing is the opposite travel angle, your behind the weld puddle pushing it forward. The more tip back you get can help flatten out your weld.
As far as I can tell you have some sort of shielding gas problem, thats whats causing your prososity. You have hydrogen in your weld puddles because theres no gas protecting it.

keep your eye on the puddle and read it. and watch your stick out which is the unmelted wire coming out of the gun should be around 1/4 to 3/8 of an inch from the puddle. the more stick out the less amps your welding with . When checking gas flow your holding your trigger and set at 25. When trigger is off should jump up

stupid question but, how clean is the metal before you try to weld it? it really has to be clean to get decent welds. run a wire wheel or flapper disc on the material you are welding until its nice and shiny bare metal. i would just start with the basics after that, make sure the gun is close to the welding and you arent pulling away. double check that the valves for the gas are all open, etc. i know this all sounds really simple, but its really easy to forget the basics sometimes.

i have a miller auto set (211) i NEVER use the auto set feature...i go by sight and sound. did you snoop your gas connections? just dont go too high on cfm cause then you just draw in air kinda like a venturi. make sure you have no cross breezes going across your work, that will just blow your gas outta the way.
to me it looks like your either going way too slow or your wire speed is too high. jmho

I use the Hobart 210.. I run 30-35cfm on my machine... I dont know what the manual calls for, but that was what I was taught many moons ago.
ALso where are you welding.. is it inside, or outside? Even a slight breeze can blow the shielding gas away.

No doubt about it. You have a gas problem. 20cfh is fine while the gas is flowing. Make sure there's no breeze. Windy or breezy conditions will blow the gas away. Clean metal helps alot too, for a nice weld. Are you using a flow meter or just a regulator? Flow meter has a 4" (or so) tall glass cylinder with a ball inside that reads your cfh. Also make sure you hear the gas flow when you squeeze the trigger. I like to hold it close to my cheek to make sure I feel the gas as well as hearing it.

I know it's been mentioned but re-check the way the welder is wired. I had the exact same problem a little while back.
