Todays welds

I've only MIG'd once, not enough to get an idea if I like it or not. How's it working for you?
 
Hey Charley; For tips on settings use the Miller App thats listed in the sticky at the top of this welding section. I've found the settings to be better than anything I've come up with on my own, and I've been mig welding for 25yrs part time. You can tweak from there. There's also an online version that you can use on your computer.

I've found Mig to be the easiest to learn and the most productive process ever invented. It's quick and easy compared to tig. The trickiest part is getting the settings right, but with that app, it takes all the guess work out of it. Also Jodi over at weldingtipsandtricks.com has a slew of videos on mig welding that are very informative. http://www.weldingtipsandtricks.com/Mig-welding-tips.html

Getting a good ground is also key to getting nice consistent welds. Theres a little trick about using fine stranded copper wire to sandwich between the ground clamp and the work piece to get a superior ground to just the ground clamp alone. It works great and now i have a couple of those stranded wire pieces hanging around that i use all the time. It makes a world of difference, because you get hundreds of grounding points rather than the one or two that you get with a clamp alone.
 
Those look pretty good to me. Admittedly, I'm a very novice welder and know very little at this point. I watched many of the clips mentioned above recently, and it looks easy in those. I guess a lot of practice is in order here! Nice work.

Made some welding horses at work today. Settings were 28.2 volts, wire feed 670, gas 90/10

At that voltage and 90/10 gas I am assuming it was spray transfer. If that assumption is correct I would have expected them to look more like the first and fifth photo ... without ripples or very little ripple ... than the others.

Unless you were purposely going for the "MIG like TIG, stack of dimes" look :))

Not that any of them look bad. They all look like they will get the job done. Just an observation.
 
nice squirtin' it gets even better the more you squirt!:welding:
you can roll out a lot of weld in a short amount of time.
 
Wish my welds looked that good Charley-------- just haven't put in enough hours welding yet.
 
Looks pretty nice. Just an opinion, though. If my weld was looking like that I would slow down just a half a touch. If I started seeing undercutting I would back off the heat a little then. Sometimes when I weld something unfamiliar I set up a test. When I like the look and feel of the weld I will take a hydraulic press/jack to it and see how it holds under the extreme force. It should bend more than break/tear. You get to see penetration that way too when you finally kill it. The easiest welding I have ever done was on 480v mig. It was set up with flux core wire AND mix gas. The slag peeled up like a catapillar when things were right. It would make a tink tink tink a little behind the weld as you went along. That sound meant A OK. It also had no ripples to the weld wether or not you moved the tip. (half moons or whatever) Happy welding! It brings me peace
 
Not bad, Charley. Sometimes, whenever you get curious, weld up a tee section and then saw it across the section and mill then grind the surface flat, then lap and polish the surface and you will get some idea of the penetration you're getting. You'll be able to see the difference between the weld bead and the base metal. With those settings, I'd expect you did fine on penetration there.
