Errrm...wow!
With what settings did you weld this taz?
Looks like you're not high enough on amps....wirespeed too high...errrr, wow!
keep practiscing!!!!
Travel speed looks way too high on some of them towards the bottom of the pic and the ones towards the top look like you're using a stop-start technique which isn't ideal for learning.
Looks like you've got next to no gas coverage too. Are you on disposables? Welding outside?
What thickness is that steel? Looks quite thin judging by the blow-holes, use something around 2-3mm for practising your first attempts on, go thinner as your technique improves.
A good friend of mine, who is a TIG fabricator by trade, will spend 10 times longer doing the prep than the actual welding. And after applying this ethos I have to agree! Welding to clean, crap free, well prepped joints is a damn site easier and less stressful than just trying to bang it together.

You always need to grind off the surace "mill scale" and/or rust to shiny metal underneath, to make sure you have a good contact point to weld on. Let us know what welder you are using and what settings you have it on, as well as the thickness of the metal. You may be better off with thicker metal to start off.
Hi Tazzy
I will repeat what the other guys have said....preparation, preparation, preparation, ....and practice
Even the very best welder when using a different machine has to get the settings (wire speed, amps, gas flow) right before puting down sound welds, and the way to do that is by doing some practice welds
hi guys thanks for the advice i am using a clarke 135te turbo mig welder i am using disposables bottles and Welding outside the wire feed is on 6 what wire speed do you advise?
Perhaps you should try a bit indoors just to see if the wind may be carring your shielding gas away. Not sure about the wire speed though. These seem to vary from machine to machine. Maybe someone with a similar machine will come along soon to help with that one!
Can you make the next lot of photos a bit clearer? I suspect from the last lot that you are very short of gas. Flat penny on penny welds can be a characteristic as can brown stuff immediately beside the welds. Spatter and holes in the welds would be other characteristics.
Difficult to judge from the photos so I could be miles out. Too fast even if you are short of gas.
how close are you holding the tip to the metal. try slowing movements
start a weld and try and cover a distance of 30-40mm in about 5 seconds, have a look at the weld and go from there
