I've got some proper gas to weld with rather than the little chuck away bottles, I'm all excited. Had to share it, the guys at work and the mrs think I've gone bonkers.....
Only thing that concerns me is the bottle threads look a little dirty, just give them a clean out before you put your reg in just incase there is any loose crud floating about. No problems with mig gas, but if that was oxygen i wouldnt have accepted the bottle because of the corrosion, and wiping it out could introduce something that might react.
mark you will find you have so much more control with a proper bottle, and welding will improve as well, because you will get a more constant flow of gas, Argon mix is far better than trying to cheap skate it with pub gas, and at the price you paid its a good deal
Got it all hooked up this evening, what a difference it made, welding improved by at least 100% Well chuffed.
Only thing that popped up was when the metal was cooling down a couple of silvery spots appeared, looked like gas might have been escaping. It was a lap joint I was playing with, and the back was open. Might I have been too keen with the gas, the hiss was louder than with the little bottles.
