It really depends on the gas your using when welding too. Sometimes your in a well ventlated area so a normal flash mask can be used, but if the area dose/is known to not cycle air well a gas mask can be required/recommended by the job site. Most gas used is Argon and if breathed in for long periods (without the occaional breath of fresh air) it can damage your lungs.
