And some test welds. What do you think?

wire speed to high - the bulge of weld looks quite high.
The important question is how much penetration you've got. weld an end of square steel tube to the middle of another tube, at a 45 degree angle
cut into the weld along its length till your half way through the weld bulge, then hit the metal backways and forwards with a hammer till something
breaks. Hoepfully you'll find the parent metal stuck to the weld and a ragged edge on the tube. If the break is the weld then ..... need more
penetration.
Also, you should be using either co2 or argon & co2 mix not pure argon (although why not pure argon i don't know so perhaps it is
acceptable).

I tried some welds after altering the adjustments of the machine. The wire speed is now at 3.5 (from around 6-7), the power setting is 2 out of 4 and
the gas is around in the middle of the pressure range (i don't remember the actual figure though).
The welds are less high now but i have lost a bit in terms of looks and i have noticed that around the weld there is a messy surface like microscopic
spatter.
What do you think and what should i do now to improve my welds?
Do you think that by using a 75/25 Argon/CO2 mix my welds will look a lot better?

MikeR is right, pure Argon is wrong for Mig unless your welding aluminium.
You need a argon CO2 mix, which should give you nice clean welds, I've welded using pure CO2 as well and have got good results in the past but
the Argon mix is the best
