Choice of machine plays a big part in the proceedings,I have had to buy one as the one I used to use went with the job I had been unfairly dismissed from so purchased a Siegen 180 and after a little fiddling the bacon is frying nicely even though its using cellar gas c02 at £10 a bottle.

I test my welds with a big hammer!
  It was 90˚s beforehand. by CTWV50, on Flickr It's not pretty but the 2mm box started to bend before the welds even thought about breaking. Need to see if I can fold into two but I'm a lot more confident thanks to this thread and some further reading. Big BOC Argoshield bottle and £40 reg helped, just need to refine my technique a bit to be more economical but happy all the same. Tried to switch to 0.8mm wire but the wire just kept exploding on contact with the work piece so I panicked and put some more 0.6 in could be down to the feeder but not sure.

Thanks for the reply Michael, I did grind back the steel and bevel filed the ends of the tubes so shouldn't be contaminated. I'm using BOC Argoshield at 10 L/min. Might try heating the steel first see if it helps to remove any contaminates. I'll finish the weld and then a big bubble will grow where I finished. I'm not a great welder as I'm inexperienced, should I try more of less gas? I'll also try a test on some other steel I've had more luck with.
