The welder is recognized as the top athlete among the metal craftsmen. They need to cope with harsh work conditions such as fumes, constantly changing levels of brightness and heat. Additionally, welders have a high level of responsibility. A flawed welding seam might, in extreme cases, be the cause for deadly incidents. Hence, a perfect welding helmet becomes increasingly important. It makes the weld process safer, more efficient, more accurate and more comfortable. Therefore only the best is good enough. So do not settle for anything less! Discover the uniqueness of the Optrel e684.
