When using a mig/tig welder you need a face sheild that has a # 10-13 shaded lens due to the intense flash/light it gives off. Now when using a Oxyacetylene torch you need to use goggles with a # 5 shade. Yes Oxyacetylene is not as bright as mig/tig welding but you still need to protect your eyes and not with just clear lens safety glasses. Welding Goggles are designed to protect for certain types of Gas Welding or Oxygen Cutting. Welding Goggles not only protect your eyes from the heat and flying debris, but also from intense ultraviolet and infrared light. Not wearing Welding Goggles can give you Photokeratitis, a painful condition similar to receiving a severe sunburn of the cornea! If I found out my kids 23 year old shop teacher wasn't teaching the proper safety methods in shop class, there be hell to pay. Safety first!

Just sayin
here there everywhere!
