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

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.

A number 5 permanent lens is too light for welding. It's for a cutting
torch or something.

Auto darkening lens have two numbers associated with them. The first is
the lens darkness with no welding going on. The second is the darkness
when triggered by exposure to the arc.

A number 5 auto darkening lens would allow you to still see through it
slightly when not welding but would then go to a higher number when
exposed to the arc.

Depending on the amps being drawn, you want at least a number 10
permanent lens or an auto darkening that goes to at least 10 for flux
core welding.
