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.



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.



Thanks, I thought it was weird that I could see inside the house with
the goggles I got from Santa Guess he isn't a welder... I will shoot
them back and get a Hobart Helmet or similar... with a 10 or higher lens.



At least you won't be learning from the practical joker who first showed
me how to TIG weld. He set up a small metal plate with another small
plate standing on edge on the first and told me to weld them together
along the edge where they met.

One plate was stainless steel. The other was aluminum. He and his
buddies stood back and laughed their asses off as I muttered and swore
in frustration.
