In the workplace, dealing with argon at low amperes requires an excellent mask like this one. Everything is captured by the filter. Some pros: Excellent filtration quality, high-grade plastic construction, and a comfortable headband, despite having some jamming issues. First, let's talk about the price. A certified filter that has four units is not a bad deal at all considering the price. Some disadvantages: The imbalanced attaching of the head to the mask is, in my opinion, the most significant disadvantage. In spite of the fact that the mask has a moderate amount of weight to it, the center of gravity has been visibly moved forward. My opinion is that controlling the light filter from outside the shield is not the most logical approach. Furthermore, the switch for the stripping mode is embarrassingly small, and you have to wear gloves in order to adjust the regulators for the other settings.
