I am, I thought it would be better to have both hands free and be able to see where the tip is before pressing the trigger.

Good pair of gauntlets and a fireproof apron are a sound investment too

I have a pair of thickish leather gardening gloves and to be honest they are a little short. I think when I order the spare tips and shrouds i'll check in a pair of long MIG gloves and an apron.

yes both hands been free is best ,if your welding your disco puddle welding (making your own spot welds by drilling holes in top or outer layer to fill ) is a very usefull technique

Be fine if wearing long sleeves but gauntlets are far better and only £3 a pair for cheap ones
That all makes sense Rob. From what you describe about the wire speed and looking at the condition of the tip after a 'go' I think you may have nailed it, the arc is certianly cutting in and out. Now you've mentioned it I can see the issue, at the time I was totally confused.
Guess how I am able to describe it so well :suspicious: I went through the same steep learning curve a few months ago!
The spares pack is a good idea to have in stock too.
I have been using 0.6mm wire for all my welding on the Disco
You got to do all the preparation work, and when she's hot and the juices are flowing, you can adjust the power and speed to maximise your penetration!@Oldseadog.
What part of my 1st date do I tweak to get the power and speed adjusted!
If you try and rush things, it ain't going to happen!
This is how I got the youngsters interested when I used to teach welding and fabrication at a local college!

So todays efforts..........
This is what the settings were for all these: http://i1254.photobucket.com/albums/hh606/Jebbus12/IMAG0436_zps4c4d33e8.jpg
This was an attempt to join two bits of scrap together: http://i1254.photobucket.com/albums/hh606/Jebbus12/IMAG0443_zps4d6865e7.jpg There was zero penetration on the other side. This would be too low power or me moving to fast?

This is the other side of the previous image: http://i1254.photobucket.com/albums/hh606/Jebbus12/IMAG0439_zpsefdedde3.jpg Is this enough penetration?
Again, thanks in advanced for scrutiny!
A side note. I did actually spend a fair bit of time cleaning the plates. For some reason after welding them they go brown!? I am guessing the metal is ****e and the rust is all the way through?

I'd say turn down the feed and power up a tad and then try and move slower in a n shape as you work up the weld. Remember to push the torch instead of pull

Thanks Evil, I'll give that a go. I have read about pushing and pulling the torch and there seems to be equal number of people saying either is fine. I pulled with these, the next batch I will push

Pushing is better IMO

You have to take a but more time when pushing so it heats slightly longer and gives a stronger weld I find
Push mig, pull TIG and oxy

don't use pub gas it' not pure .
you can get clean co2 from most fire extinguisher places like arco . i pay £12 for a pub gas bottle refill

There's nothing wrong with pub gas
He isn't using pub gas, he posted earlier that he was using argoshield
Agree with Evil pushing will give you better gas shielding coverage.
Cant tell for sure if this joint attempt was overlapped or butt welded?
If doing this as a butt weld I would start on 2 (low) and place several tack welds along the joint every few inches. This ensures the heat doesn't pull the work pieces apart as you try to place a run of weld.
Then start to join the tacks up with beads of weld possibly upping the power to 3 (low) Welding two sheets together you should push and also weave / zig zag between the two sheets keeping an eye on how much heat is being generated.

Methinks its butt. I go with a high ish heat and tack everything in place then turn it down and seam
