My aching eyeballs after practicing FCAW.

5 minutes? Nope. I sit at least 1/2 hour.
Welding jacket? Good. Can get lightweight ones. Not a lot of money either. I have an 8,000 lb leather one.
Weld burns from the glare? Very harmful,wicked sunburn. if i need to weld bare hands, its at least nitrile gloves. Most often good leather gloves, not them 5 cent fuzzy leather ones.

so its not just a helmet, its all the gear to keep you safe. No welding with crocks on!!

i wear proper steel boots, 100% while in my shop
