How bad do I weld?

Looking for tips on learning how to weld. I am just kinda learning myself as I go along. What should I be doing differently. My welder is a cheap one, $120 special from harbor freight. Flux core only, high/low power setting only. What should I do differently?

your weld should sound like bacon frying. Try using some anti-splatter spray as well and make sure its spotless with flux-core.
Kepp practising, it will come.

How bad do I weld?

the late, great Jim Davis taught me to (when welding in a straight line) to use a "horseshoe" sort of motion with the tip ... end result is try to make your continuous welds look like "a stack of dimes" ...

Not that my welds are particualrly wonderfyul all the time, but that bit of advise took me a long ways toward improvement.

Obviously, the material thickness you are welding will determine what technique is best, but on heavier plate type situations where the idea is to lay in a bead ... that was great advise for me.

I have a 110 MATCO wire feed with Argon tank ... seems to handle all I do here at the house.

Yah, thickness is what is tricky for me. This one was interesting because it was a thick plate to a fairy thin muffler. I think the muffler is less than 1/8" while the plate I was welding to it is 3/16"

I think thats a damn fine effort for a beginer. If you hav'nt already invest in a slag hammer with a brush on it as it helps keep things tidy. The horseshoe motion is a good idea for creating a nice "tornado" or "stack of dimes" weld.

Looks kind of hot, thats probably where all the spatter is from, when you are welding thick stuff to thin, lean on the thick stuff so you don't melt and burn through the thin. Keep practicing, and you will have it in no time.

I am not of fan of flux core non gas . I like argon myself. The horse shoe or mini circles is a good thing. Steady consistant movement is important as well. SLow pace but not to slow. Like said before PRACTICE PRACTICE!!! YOu did a great job for a beginner.

I do not do much better and I am always messing around I just get some steel and go for it I know that since I got the autodarkening I have alot better luck with starting and I think if you did get a gas welder you would be doing a lot better too much splatter with the flux core. Keep it up looks good!

One thing that made everything make sense was: " think of it as melting a candle together, don't give it enough heat or penetration, the wax will only lay on the top of the other candle" Confuses you a bit, but you should get the point.. And practice!

I've never used the flux core wire and have always used the 75/25 argon/CO-2 mixture with .028 or .035 wire. So I'm not an expert on what you're doing. I do agree with F15's assesment, though. Concentrate your heat on the thicker material.

Looks like typical flux core to me...heat doesnt look to high since the surrounding metal isnt burnt away. Your also gap welding..wich isnt the easiest thing in the world to do, work from the thicker metal to the thin stuff. Also play with your wire speed till you get it the "bacon cooking" sound. Remember if you weld is building on top your heat is too low, if its blowing the metal away its too high. It all comes in time and the more you do it the more you learn. Ive gone to not welding anything at work to welding everything in the last year...practice makes perfect!

Good start...keep at it. You'll need to watch out for your undercuts...where you burn away too much of the parent material and not enough wire. Pay attention to the heat. It'll get more tricky as you start practicing with thinner metals...like quarter panels and such. I practiced on my junk 65 'stang quarter panel. I just cut it with my sawzall and welded it back together...did that 3 times before I got the hang of it.

I agree with chilly460...everytime I start welding I have to "get used to it" before I can make any welds that don't look like bird crap.
