What a difference some Gas makes

[UncleSatan]

Using the No Gas Flux Cored wire my welds were just a splattery hell

But this morning I got some gas and here are my first attempts

Not perfect by any stretch of the imagination, but an incredible improvement.

Obviously with these I was playing around with power and wire feed, but any constructive criticism would be gladly received.

You used gas with No-gas wire? Certainly, someone will explain it is bad combination...

I think we're moving from gasless in the first photo to gas with solid wire in the second photo.

You can see a lot better what's going on with the weld pool with a shielding gas - makes life much easier. In the second photo the penetration looks good or too much, but the welds look narrow. Maybe both power and travel speed are too high? What thickness of metal is that in the second photo?

Zst: No I used normal wire with the Gas, sorry I should have explained better

Malcom: The metal in the second picture was about 1mm, will try slower on a lower power

...and what gas is it?

Your welds are looking good.

I hope that the Agent was very helpful. Please let me know if there is anything else that I can help you with.

I tried to go up to welding 3mm steel and was having difficulty with the welds being too high and so not hot enough.

So I tried going very slow with the wire feed higher, but still couldn't get good results so looking to the welder, my tension was too high

After sorting out my welder, it I was a bit happier with the results

On the flux cored wire it looks like there is some sort of coating on the metal did you clean it of first? Because that would not of helped if you didn’t
