Welcome to the forum. Sorry there were no replies for so long - for my part I've had the most manic week ever.
I tend to experiment with the gas setting to get it right. Not enough gas will leas to a porous weld - full of holes. I normally use a test piece of steel and regulate the gas down until the weld starts to go porous, then regulate it back up a turn. The idea is minimum gas for an acceptable weld (for economy).
You might to turn the gas up some more if there is a little wind, if you are welding slightly less clean steel, or if you want to cool the steel quickly.
Hi Malcom,
Thanks for the reply, I'll try this technique first thing in the morning. I really appreciate your help and the sites brilliant.
Oh please excuse the spelling mistake (WETHER instead of Whether)
in the original question.
Thanks again

Nice article (that I've helped with a bit ) Gives rough guidelines to litre/minute settings. I started with that, figured the flow meter on my reg is near useless (cheap Clarke thing) and instead adjusted it till it gave the right amount out.
To measure it: drink the beer from a pintglass and fill with water, then invert it (while still full of water) into a bowl/pan of water. Bubble gas into it*, and time how long it takes to displace the water. There's about 2 pints in a litre, so 10 l/minute should empty that glass in about 3 seconds. 15 l/minute will empty it in 2 seconds. Do your own maths for more examples
DO NOT STICK THE END OF YOUR WELDER INTO THE WATER! (Use a separate tube or something). KEEP WATER AWAY FROM ELECTRICITY.
Disconnect welder from mains first. Do not do this in a lightning storm. Do not operate machinery while hands are wet. Do not operate machinery while drinking that lovely beer. Make sure an adult is present. Etc.
Hey,Mat-C easy for you, you have real beer I'm stuck with
!@#%$ instead of beer! Guiness and Boddies are expensive imports.
BUT the weather's great and I am allowed to own guns.
