I seem to get a slight cover of white dust on my fillet welds when tig welding at high amperatures, does any one know the reasons/effects of this. I have tried all the obvious fixes(gas lens, changing work angles, more, less gas, ect.) to no avail. It's the same dusting that occurs normally on the outskirts of a normal weld, it just covers the weld it self. Any help is appreciated.
No announcement yet.
