Welding advice

I wasn't going to correct the psi thing until he was more comfortable welding. I don't like correction get too much at once. But now that it's out there, newb. Jk
 
I will, a friend wants me to burn on some shock mounts to his rear axle this weekend so I need to get to know my welder a little more before I'll commit to it. I think this might be the best mod I've ever done though.
 
This, drag is for stick welding. I push all micro-wire and flux core. On the 1/8" stuff in your pic, try it with heat on 4 and leave the wire speed alone. Frankly I don't manipulate the puddle much at all...just a straight push. Stack of dimes is a TIG thing, not MIG.

As for gas setting, all y'all need to re-check your gauges, it ain't psi you're looking at, it's CFH. For .030-.035 I run at 20 minimum, and up to high 20's if there is any sort of breeze.


I started out on an old buzz box using 7018 rods so it took me awhile to get the quality of welds I used to get with a stick. I worked in a small fab shop after-hours and the guy running the shop said " you sure weld pretty good for doing it completely wrong". :haha::haha: :haha:

Well I kept the wire speed the same, pushed it instead of pulled it. Bumped the voltage up a notch and here is how it turned out.

Not gonna I practice on simple not really essential stuff so I'm not wasting wire or gas or metal. I'm building an engine and trans skid for my jeep.


Only thing I would change is over lap the corner welds a little more or weld solid around the corner and joint in the middle. Whatever is easier for you depending on the piece that you are working on.

Yeah I though about that. I ran the long beads and was like **** I should have went all the way around it.
 
Looks much better, good bead profile, looks nicely burned in without undercut. The stop starts in the corners don't bother me. Grab a wire brush and brush some of the smoke off it...it'll look even better. :waytogo:
 
Thanks guys. Yeah I feel like pushing it helped me keep it more uniform, and I needed that little but more heat.
 
For future reference the weld profile is the best way to determine if you have enough heat. What you have now is ideal. If you brush up the weld you took a pic of you can take a close look and see how it's fused at the edges nicely. This is what you should be aiming for.

FWIW, I always aim for the hotter side of things (voltage) and if it's a bit hot for the material i'll turn up the wire a bit more and go faster.

Thanks for the tips I'll appreciate it
 
Did you start at the top and work down? Gun angled slightly up to hold the puddle up?
 
That's gravity for yah. Keeping all the heat in the puddle making it drip. Since your welder doesn't have fine adjustability for voltage that will happen. Happens all the time with my Hobart. My Miller just dial it in and let her rip.
 
Going up with MIG is quite different than doing so with stick. It's all about the heat setting...then with the gun angled up about 20 degrees it's just a straight push up, no weave, no manipulation. Keep adjusting wire speed and voltage down til you end up with a decent looking bead.

FWIW a downhand vertical weld with MIG is right there with JB weld for strength...I'd only ever consider it for thin sheet metal.

That's why I tried to do the upside down Vs going up. I ain't doing that again might as well smear bubble gum on it
