My set arrived over the weekend, tried it out Monday. Fit up is fine but I found on alloy a very dirty porous weld even tho argon certainly seems to be flowing. Tried on both 1.6 and 2.4 as these are the two sizes of tungsten I commonly use. Strange thing is when same kit is fitted with a ceramic welds aluminum spot on so collets and collet bodies seem fine. REALLY ODD. I could have something fitted up wrong but why does a no8 ceramic work ?

I do have a lathe but I cannot be bothered. Rather get on with projects than wasting time on this.I ordered the #12 ebay kit aswell. Same results. I did notice compared to my Furick cups, was the ebay cup had a sharp edge, compared to the furick had a nice smooth radios.
Im Guessing this has some sort of Venturi effect? If i had a lathe...Would be worth turning the ebay cup with a radious edge and see how it performs.
