Thanks... I won't buy the HF one... Still, I have a hobart goggles with

permanent lens and it says #5... I am not sure what "#5" lens signifies?

Could of course Google, but if you got a quick

explanation/reccomendation, go with it? The hobarts I got allow for lens

changes...



The number is the shade. I prefer something in the 11-12 range for my

stick machine. I don't think I would do any kind of arc welding with a

#5. That is more like a gas shade.





What about a MiG wire feed? Or is that one of the ones you mentioned above?

MIG stands for Metal Inert Gas, and is a form of arc welding. The wire carries the current and is the filler, and the gas flowing from the gun shields the arc. The flux in flux core wire generates the gas when it burns instead of having to have a gas bottle and its associated regulator and plumbing.
