Is this an actual bead, or a series of tacks? If it’s a bead, trying running just a straight one, instead of all this manipulation.
Will do, thank you!
Flux runs hot. Less manipulation. Just run a straight bead.
Alrigjt thanks!
Make sure your running electrode negative with that self shielded. Go ahead and turn your voltage dial up to the next setting, you may have to adjust your wire after you see how it runs. As far as welding with gas, its easier in my opinion, but you have to be careful of the wind, fans, anything that will move your cover gas away. I personally love Lincolns NR-211-MP self shielded flux core.
Okay, and I should be doing no movement pattern and dragging correct? I believe I am using that wire actually!
If its running hot enough and your metal isn't too thick you should only need a very slight motion. Just enough to be sure there's no undercut.
Okay thank you! Is this looking like I’m on the right track besides the variation in width at some points? Would that hold these steel doors on the hinges? (In the Imgur) Or would I need a triple pass?
Thats what it should look like. Good solid weld.. Don't mind that spatter, its gonna happen with that wire. I might put one more pass on the square tube just to be safe. How heavy is the door? Would it justify another bead? If its not too heavy, that'll be fine.
This is fcaw on 1/8” using .030 wire. It’s a Hobart handler 140
I’ve been welding through my school for two years but I just now got my own machine, I know what a good weld should look like and ive gotten some solid ones with the expensive Miller rigs at my school but this is about the best I’ve gotten with the handler, any tips on what to change?
Your later picture looked good (in comments here). Seems like you got it dialed in. Nice and simple drag, 10-15 degrees back, and you shouldn't have to do any fancy manipulation - just move forward steadily.
My Flux Core I always seem to need more heat and feed to get consistent results, as opposed to what's suggested on the box. Clean all your metal well!
For the doors, tack things in place first and then once you know it's good, weld them out. Don't be afraid to cut a tack - and watch how much heat you put into the pieces. You can and will warp the metal, so space your passes out opposite corners, sides, pieces, etc. Let them air cool for 5-10 minutes between if need be, especially when dealing witn thin metal.
I assume you know how to layer beads? Root pass, bottom pass blending into root to make a shelf, and then a top pass over that - joining down into the previous two?

Turn your heat up like 1 or 2 volts and just drag it. Flux-core don't need all that movement unless its self shielded.
The Hobart handler only has a few preset voltage settings, should I move it up one whole setting? I am running self shielded though, haven’t quite gotten a gas tank yet. Would it be a lot easier to weld with gas?
