Is P2 mask OK for welding?
Respiratory protection and good ventilation are a necessity! ... P2 rated respirators protect against thermally generated particulates (which includes those given off when welding galvanised steel). You may also notice an odour or sour taste from the fume – if so, using an additional odour filter will help.
What kind of welder do you need to weld galvanized steel?
For galvanized steel, a standard arc welder is probably the best way since arc welding is versatile, and the alternating currents allow you to create a good arc that can melt the flux quickly. Arc welding sometimes creates flux, so you may want to work outside if possible.7 ago 2021
Can you get poisoned from welding galvanized steel?

Severe cases will align with symptoms of the flu like chills, cold sweats, vomiting, fever, and shaking.22 may 2018
Does galvanized steel produce toxic fumes when heated?
Zinc toxicity can occur when an individual is exposed to and breathes the heated yellowish fumes produced from welding or heating galvanized steel. For hot-dipped galvanized steel the recommended maximum temperature is 392 F (200 C), before the metal presents a toxicity risk.
What are the side effects of welding galvanized steel?
