You do NOT use "goggles" when arc-welding. You use a proper face-shield (mine is the auto-darkening type), and you should not expose any skin to the arc's intense UV radiation.
A darker helmet shade, compared to gas welding. A shade of 10 for 70 amps, it works up from there, or you could buy a auto-darkening hood which you can see out of, but when you strick the rod on the metal it darkens to the right shade for you to still see out of.
An electric welding arc produces ultraviolet light and the UV light will damage the retina. With a good welding helmet, your eyes will be protected, but you must have the proper shade (somewhere between 9 and 14 depending on your amperage) and if using an auto-darkening helmet, it must switch on quickly.

SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
Safety awareness, Welding helmet, gloves, welding jacket, welders hat, chipping hammer, safety glasses, heavy pants, leather shoes, hand grinder, and a wire brush.
If by gas welding you mean-oxyacetylene welding. The difference is just that arc welding requires a darker shade of lens. When oxyfuel gas welding (OFW) usually a shade 5 lens is recommended. When arc welding, a minimum of shade 10 lens should be used (actually shade should be determined by amount of current used).
The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.
The most important equipment you can have is your safety equipment, your gloves, visor and heavy-duty clothing. You have to have some sort of a power source to generate the electricity necessary for arc welding, so I'd say a power source is your most important arc welding equipment.

It protects your eyes from the bright light of the electric arc and covers your head and neck to protect you from sparks.
If you are asking for the correct nomenclature it is Shielded Metal Arc Welding.
Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.
Yes, arc welding does create ozone. It is because the temperatures created during arc welding convert the nearby oxygen to ozone.
