Ronnie has hit it again,.6 for light stuff and .8 for commercial.
I use a commercial set coupled with a spot welder that at full duty will produce 1,000 amps and when the trigger is pulled the 1 1/2" cables jump alarmingly upwards.

How interesting. The welding gear vendor I bought my set from told me I can get more power from the welder if I up the wire to 1.0... Any comments Ronnie?

I expect it's more a question of technique than anything else. A good welder will get good results with a variety of set-ups, and a bad welder won't.

Furthermore, a good welder will get better results with a particular set-up than he would with another set-up, but another welder might find he prefers the other set-up.

You get the same thing with guitar players. In the end, it's in the fingers.

I'm sorry, no offence intended! Must be the language barrier.

Alga, I dont thinkk theres any easy way to explain it but. A MIG power source has a Flat characteristic, i.e small change in voltage = large change in amps, this maintains arc length. pull torch away from workpiece arc gets longer resitance increases amperage goes down burn off rate reduces wire gets closer to workpiece correct arc length is maintained. Increase the wire diameter to 1mm and maintain wire feed your pushing more wire into weld pool therefore more amperage required to burn off wire therefore more heat into workpiece and more penetration. Having said that the voltage will obviously need to be increased. Now if your welding set you have purchased has the capacity you will certainly be able to liberate more power and a higher current density from larger wire diameters.

lets get back to the question asked.

those welds look fine. dont worry too much about the height thats what the grinder is for.

just thought id add my 2p's worth
those welds look ok to me
I always use .8 but if you use .6 just turn up the wire feed

I always use .8 aswell but as someone previously said its what you feel most comfortable with, if you got your settings correct both should achieve the same results.

Those look good enough to me.

Once you have more experience and confidence in your welds you just "know" when its penetrated properly....... oo er missus
