Welding welding welding well sucks

OK I feel almost better. I am in the middle of replacing my quarter panel skin. I had to repair my wheel wells around the flange area. As soon as I hit it with the Mig welder it blast a hole in the steel. I bought a Lincoln MIG 140C it is set up correctly I checked and doubled checked it then I called Lincoln to make sure. I have the correct Argon CO2 mix as well. So what am I missing do I just have to work though it any body workers out there.

I have that same welder. Try turning the heat down a bit and increase the wire speed by a bit. After you learn the basics, welding is all about practice, practice, practice. Use the old quarter panel to practice on and to figure out the correct settings for the welder.
You'll get it Mlarv, just keep practicing!

I know practice. I need to get the wheel well flange done today or tomorrow cause the skin is being put on Saturday during my class. I have the welder set on "A" and wire feed set to 3 using .025 wire. I am thinking I might switch to .023 wire which means I need a new sleeve and tension roller. I will talk to the instructor and bring the welder with me to see what I can see.

Thanks

Are you welding good steel? The wheel well is new you said but what about the piece you are welding to? It's hard to get a good bond with crap metal

My voltage is usually up to high when the happens to me or my wire feed speed is to low

My neighbor is a machinist, whenever he has run into a problem like that he puts a cold wet rag on the other side of the metal to absorb the heat, if that doesn't work the steel is probly too rusted to weld

Yep, turn the heat down. I'm no welder but I learned a lot when I put new floor pans in. I too blew some holes through the metal until I got the setting correct. Like anything else...practice practice and patients

Well got the answer to my problems on this.

I was using the schools welders and never really did have a problem with them. I asked the instructor about the welder I have and what I was doing wrong and he laughed. He said the wheel housing and the area I was welding on was really thin and rusted, The more rust I removed the thinner it got so I was in a no win battle. He looked at the welds and said considering what I was up against I did a good job

I have some spot weld to do in the same area but it should not be as bad because there is a lot of new steel to weld to.
