Aluminum can be found in many alloys, e.g., Copper, Nickel-Chromium, steel, zinc, magnesium, brass, and filter materials. Breathing in fume containing aluminum while not wearing a respirator can irritate the respiratory system.
The workplace exposure standard for welding aluminum
The aluminum workplace exposure TWA is set at five mg/m3.
This means that the highest average airborne concentration of welding fume containing aluminum, when calculated over an eight-hour working day over a five-day working week, must not exceed five milligrams of substance per cubic meter of air.
Welding respiratory protection when welding aluminum
Below is the advice when using MIG, Stick, TIG, Plasma welding, or cutting
The best atmosphere with forced ventilation: A powered air-purifying respirator is advised.
Limited ventilation: Gas filtration and particles via powered air respirator with a high-efficiency filter and Al gas filter fixed.
Supplied air is forever advised when working in a limited area. A powered and supplied-air respirator must never have an atmosphere immediately dangerous to life or health.
Types of welding respirator
These kinds of respirators are generally used by people who wear welding helmets. Because they are disposable, they are typically made from lightweight and thin materials so that you can be amazingly worn under a helmet.
There is no cleaning or maintenance required for this type of respirator. It also does not get in the way of movements. You can discard it when it is not being used.

Power air-purifying welding respirators
These welding respirators are generally linked to your welding helmet through a hose. A blower inside it forces the best standard air into the filter or purifier, the respirator.
This is the top when it comes to coverage, as it can save not just the lower part of your face but also your eyes or the entire force.
