This is my first time welding with GAS, so please be nice...............

Am I moving to slow or not hot enough? This is the welder I am using and It will really just be used for exhaust and intercooler piping, do you know what settings are best on this?














I just don't know why they look like there sitting on the metal. I can see it penetrating but it still not flush.

Thanks for any help guy.

 

I would slow down your wire speed a little bit

remember mig isnt going to look perfect, but can still look good

for piping i would put the power on the 2nd lowest setting, maybe the lowest. wirefeed at like 50%

 

The wire speed is on 1 witch is as slow as it can go. My friend said I need to speed it up on the pipes, that is why it looks so tall.

I am also not looking for it to look like tig or anything, just want it to be a good weld.

 

More heat.

 

Ok so like I have it on 30 volts I should turn it up?

Do I need to speed up still if I turn the heat up?

 

if you want the bead to go down nope. You just gotta find the right settings.

 

you're moving too slow

 

Ok, so just turn it up and stay at the same speed.

 

I think my dumb *** just figured out somewhat of what I was doing wrong.

 

yeah it looked like a combination of not moving fast enough, needing more heat, and too much wire speed

but of course changing one of those can affect the other, so just find the setting that works best for you

 

i would use more heat and stay the same speed... by they way how much was that welder ya got there?

 

Practice on some T joint fillet welds for a while.

nice, I'll smoke that fat joint.

by the way, just open up the cover of the welder and there should be a chart to guide you as far as the settings goes. That's the best way to start. know what gauge or thickness metal you're welding turn to that setting then go on from there.

 

Thanks alot guys I will try this when I get home. I was not reading the dials and thought the top one was the heat but it was the speed. So all I was doing when I thought I was turning up the heat was making the wire faster lol.


I payed 495.00 for the welder.

Thanks I'll post some more up tomorrow.

 

I think you should practice with two plates and do butt welds, beveled plates and mig welds look best. Actually, practice on what you are actually going to do. Mig and thin wall pipe/tubing isn't very easy. The flat piece will not look right when you run a bead on it, there is just nowhere for the filler to go. Secondly, for flat butt welds, go forward about a quarter inch then back up into the edge of the puddle.

 

My welder's has been doing the same thing lately. I tried various types of setting. Could it be too thin of a mig wire? That's the only thing I chance on mine. I went from .035 to .025.

Is this any better?










I turned the heat up but it still a little high. Can someone show me what it should look like?

I tack welded the first pic witch seems to be a little easyer.

Thanks for the help guys.

 

You still need more volts. Avoid the tack weld method. If you ever were a welder and tried that **** you would most likely get fired on the spot. It leaks and it breaks.

 

I was at 3 at times but I keep getting that crackle pop and not a nice buzzz.

I need to turn up the speed as well?

 

OK do you have any idea what your heat settings translate to in actual volts? that would make it a WHOLE lot easier to set this thing up right.

 

I'll have to check this out. There are 4 settings, and I think there is a toltal of 25-140 volts I think.

 

What is your gas at?
Cleaning up the metal before welding will definitely help. But it looks like once you lay down an actual bead, you might be fine. The added heat from a constant flow should drop it down

 

I just need to see what some other mig welds look like.

 

that's amps not volts.

I can't take pics where I work or I would be able to throw you some sweet sheetmetal mig weld pics. I'll try and find some though.
