there is a lot of splatter with CO2, especially as its usually windy when i do it. Nearly all my welds need touching up when its finished.
You can buy anti-spatter spray at most welding supply shops, some of it is paintable.
Not as pleasant in the aftermath, and not quite as good, is supermarket home brand cooking oil spray. It stops the spatter sticking, but smells like
someone's barbequeing. It also leaves a very slightly sticky residue, but the chassis wont rust!

Washing up liquid does the same job - I have worked for some tight employers in my time!

Wow...! Thanks all for your responses and sharing.
I have just confirmed the Kemppi w Argoshield. It really feels much better than the rest. It sounds like bacon frying in the pan with all correct
adjustments. And yes, when the gas flow too high, the weld does look a little porous! Looking for RHS now and hopefully to start by Sep! Can't
wait...
What wire size should I go for? Is 0.8 ok? I've read somewhere (probably from previous postings) that 0.6 would be ideal. The reason I ask is,
it is rather difficult to get 0.6 wire spool. I have to specially order and that will cost. On the other hand, 0.8 is widely available. So is it
really worth to go thru the hassle and pay for the difference for 0.6 or 0.8 would be just fine tho it may not be as good as 0.6?

I built my car with 0.8. It is probably slightly easier when joining tube edges to use 0.6, but certainly not impossible to use the former. 
Dont just build it.....make it!

I always use 0.8 wire and find it builds better than the 0.6 and is much more forgiving. If you cock something up putting the power up a notch and
running over it again to flatten it out works better with the thicker wire. I don't know if it is a trait of my welder but I also find the arc
easier to control, maybe that it feeds thicker wire better.
yours, Pete.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Just a quick tip, don't be tempted to use 15Kg spools on a small welder, even if they fit and the manufacturer says you can use them. It puts a
hell of a strain on the wire feed at the begining of the weld and the flywheel effect can over feed the wire at the end of the weld. With welds only
25mm long there ain't much in the middle!

On my second reel i got the 0.6 by accident, it seemed not enough was coming out, so i turned up the feed to compensate, but it wasnt the same... i
cranked up the current for good measure. Next time i'm definitely gonna use the 0.8 again, even if it is a little harder to thread...
With the thicker wire you have the wire feed slightly lower, so it seems more relaxed - the wire comes out gentler.
All IMHO of course!

Cool! Thank you all for all the inputs! Glad to hear that 0.8 wire is better, as 0.6 is very scarce here and it will cost a bomb to special order
it.
Yippee! One bit of good news for the weekend!
Have a great weekend everyone!
