A mask such as any of these will not substitute for good ventilation. They will protect your respiratory system from particulates and some will filter out gasses but they do not prevent dust, particles and condensed metals from your torch plume from seriously contaminating your work environment. Use a mask with appropriate ventilation but NOT in place of it.
