So I dropped the heat to c and left the feed alone and this is what I got

What wire are you using?...Also what gas mixture?

Something bizarre going on.... $:-\$

Well im done for the night. Gonna sand the edges off and hopefully finish the trailer by friday. That includes taching everything in place pulling the boat off welding everything solid and bracing what's already on the trailer.

You can see the old mount to the left it was only welded to the top of the frame these should now be long enough to weld to the top and bottom.

And the cost for materials for what you see was only $32 and they cut everything for me.

According to my brother who is a certed welder the metal was getting to hott and piping while welding and that's why I was getting the popping and funky chasers that would rise out of the weld? When it was turned down I could see good penetration and was getting good lines and they all got 3 good smacks with a 12 pound sledge so their solid.

What seems funny? I have no clue really about welding.

Nothing really bad, just that thee seems to be a lot of carbonizing going on and a bit smokey...Almost like what you would have with flux core wire...

FWIW the flow rat is a bit more important than pressure, the pressure simply means you have gas present.

Have you double checked the polarity? Your work should be negative (-) and the electrode positive (+) for gas and reverse for flux core...

Sounds to me like your close..

Please understand that I am trying to help you improve your skills, not criticize, it takes a lot of courage to try something new and when I was learning to weld I needed a lot of encouragement.

Great job

Don't worry I didn't take it as criticism from the becoming. Just guidance. Thanks for your help.

Thanks for the feed back. Reason its so big is I went over the first weld because I had the feed to slow but the other 4 came out alright. Im no welder as you can tell. I just try. Im using a little 135 lincoln set on D 3ish. More like 3 1/8 and the gas is set to about 10 psi. Sound about right for 3 1/16 plate

you should not be using a 110v machine for this. Multiple passes
Don't do squat. Your welds a weak and cold. Welds like that should not be put on the road.

Ok so ill make another plate. What's your opinion on the other plates pictured?

Edit: on the first plate pictured the weld on the gusset to the right was the only weld I ran over again and the plates are welded on all sides where they attach. Thanks for the info and guidance?

Yes you are getting better. Toes still look a little cold though. You would really like a 220 machine. Here is a pic of what I am talking about.

« **Reply #38 on:** March 21, 2012, 06:19:02 PM »

Now when you say cold what exactly does that mean?

First picture on post #25. Look at the edge(toes) of the welds. They are not blending the base material in with your bead and your bead is too high. Also clean the mill scale off of the steel. Sand with a grinding wheel with 50 grit so the metal is clean and shiny. Mill scale is oxides during the hot rolling process and you have to break through that to get to the steel. This causes havoc with gas mig and really bad on TIG. Stick it would be ok to leave it there.

Did some practicing, how do I solve the cold toe issue?

And what the hell causes those chasers that bubble out

im no pro welder by any means and i get dangerous with my 220v argon mig... but doesnt it look like the bead is just sitting on top of the metal and not IN the metal like in TJ's pic?

like this:

the bead itself takes on a concave shape where as the previous weld pix are all convex and theres just a big bead sitting on top of the work?

convex:

To be honest I couldn't tell ya, hopefully tj would chime in but I think it has to do with the technique. I was taught a few techniques and the one circled is one I use the most but im sure there's more to it

Im think your problem is too heavey a material for your 110v welder .it doesnt seem like your getting penetration just piling the weld up on the surface.My 110v welder does the same thing on 1/4 inch steel so I stick weld the bis stuff with 7018 low hydrogen and that does the trick. I don't think it will matter what tecnique you try your welder is not designed for the job especially if you dont have it plugged into a 20 amp dedicated plug

« **Reply #45 on:** March 22, 2012, 12:05:03 PM »

The welder im using is a 135 Lincoln and it welds 1/4 in. So I don't think its the welder more so operator error on my part with the angle of the tip. In the pic posted a few posts back when I was practicing that was a 1/4in scrap welded to one of the old 3/16 bunk supports and it burned good came out clean and had the concave weld to it.

is it a weldpac 135 because thats what mine is and it will only weld 1/4 inch with flux core wire

Donno all I can tell ya off the top of my head is its a 135 something. Its my works welder that we use from time to time but its stored at my house.......

Only reason I started this venture is because my brothers welding teacher told us it would weld 3/16 no problem.

yeah Ive heard that before .all I can tell you is from my experience with the same welder and having made the same kinds of welds I dont't think it's operator error I think the welder is too small or your voltage is too low ie. using it on a 15 amp plug

« **Reply #49 on:** March 22, 2012, 12:33:42 PM »

Well shit. I just downloaded the manual. For 3/16 use flux core and settings D3.
