DIY Welding Helmet Ventilation/ Schweißhelmbelüftung

thingiverse

Welding fumes can harm your health, espacially welding stainless steel so me and a colleague decided to make our own 3M speedglass style vent system powered by the compressor system in our Workshop. Instruction: -Find yourself a Pressure regulator (Ebay), an old belt, some zipties, an about 19mm inner diameter flex hose and either double sided tape or velcro. -Put the hose on the printed part, attach the other end to the pressure regulator (you might have to get extra fittings) -Fix the regulator to the belt -glue/tape the printed part in your welding helmet above the darkening module (picture) -Fix the tube to the helmet with some zipties for strain relief And boom there you have your own crude but working ventilation system that keeps the headaches away Also in summer it might be quite relaxing and anti fogging to get some cold air blown in the helmet Quick tipp: aigainst noise from the escaping air you can try to stuff some cloth or carbon filters in the tube/ the printed part
