Basics

This page goes over the Personal Protective Equipment (PPE) needed for Welding
The main difference is the unique heat (conductive from splatter, as well as radiant from the Arc Flash )
Thus most aspects (at least those closer to the arc/"splash zone" such as the hands and arms, other areas are less demanding materials wise, granted this depending on many factors) need to be made of "Welding-Proof Materials" (Want a better page, but that will have to do for now)

Head + Shoulders

Some sort of Welding Cap, Hat, Durag (Piles of spelling variations for that) / Bandanna to protect forehead, hair, and partially theneck from Arc Flash + Spatter

Safety Glasses (General Shop Requirement + Extra Protection from Sparks/Splatter if they get past the welding hood) (Can also be tinted to protect eyes from others arc flash, and cutting/grinding while the welding hood is up
Welding Hood (Protects from arc flash, and dims the light allowing the arc and Weld Puddle to be visible)
Safety Goggles (Needed under certain circumstances and *guarantees* eye protection from sparks/splatter) (Some glasses have thicker sides and thus are a good comprimise in most situations=

High (and Buttoned!) Collar (- Decent Protection, but not Perfect, adequate in most situations, but can allow for some sparks/spatter to "sneak by")
Welding Shroud (Akin to the hood of a hoodie/sweatshirt, but with drawstrings and just the neck portion) (*Welding hoodie when*) Covers head and shoulders completely, only downside is overheating (and aesthetics if that matters to some!)

A Dust Mask can block and sparks/splatter that comes under the welding hood from going into your mouth!
If a fume extractor / *very* well ventilated work area are not being used a Respirator or PAPR should be used

PAPR Welding Helmets / SCUBA Welding Helmets Supplied Air Welding Helmets
- Provide clean air (and to a certain extent cooling!), usually full shielding of head/neck via a shroud and in some an enclosed "space suit" kind of helmet vs a "hood" with exposed rear and sides
- Tend to be *very* expensive (Need to see material + certification costs vs markup etc)
