HSE is the UK have just decided that welding is finally dangerous for your health after years of saying the evidence was inconclusive.
They are bringing out new regulation regarding ventilation and controls to limit exposure to welding fumes.
As if by magic the £250 welding mask respirators have increased in value to £550.
The respirators that connect to air lines are the most bloody dangerous things you can think of, effectively you get drowned or worse. You have stale air in compressors which can have harmful H2S gas content, not exactly the alternative i would be looking for.
I have been playing around with the idea of 3D printing parts to attach a hose to the back of a welding mask and using the guts of a travel hair dryer (12v) powered from the guts of an old cordless drill to make a forced air system which would be mounted in a belt back behind the operator. Just like a real one. Cant get enough air pushed through. As it is a gotta have piece of kit we will all have on our wish list, I'm looking for us all to collaborate on a share alike open source design to come up with a cheap, reliable and easy to build alternative to the £1200 Miller equivalents.
Thoughts on the back of a cigarette packet please.
