Mig Welds

[Kelpike]

I am new to the welding world. I just purchased a Marquette 110 mig welder. Right now it has the trimix gas attached so I figured I would just use it to practice. I will try and add photos for my question. My first couple of welds were rather chunky looking. After setting changes my welds started to come out kind of straight and even, but they look like a fat pencil lead. They are not spreading left and right at all. Any suggestions to acheive the so called "stack of quarters" look?

Welcome to the forum Kelpike,
I am not a MIG welder myself but we have several here. I'm sure when they come online they will assist you.

try using a circular motion and turn your welder up your welds dont have enough heat to melt the base metal.

With MIG you do need to weave back and forth. If you just go straight you will end up with very skinny welds. You may have to turn up the heat. With MIG you can run a bead and not really get enough penetration. If it looks like the bead is just sorta sitting on top of the metal like a rope and not really melted down in then you need more heat.

This site also has some good info.

Yea as Eric said you need to turn up your heat and wire speed quite a bit. Your not going to get that stacked dimes look you think your going to. The only way to get semi close is a really crazy weave or pulsed mig.

If theres no gap no need to weave but if you have a gap you need to weave to fill it.

the edges of your welds need to blend in with the base metal without under cutting if your burning thru you have to much heat, practice with different thickness of metal

[junes]

Thats not true thick sections require a weave.

[robert]

And maybe multiple passes on thick sections instead of one wide weld ,its easier to control your puddle.

Just make them more even all the way along. Keep practicing , trying some joints.

Slow down as well. Did you use fluxcore before using solid wire on this machine.
