[Noisebridge-discuss] let's get a TIG welder

[Jake]

Yes, i'm comparing soldering irons to welding machines.  they get hot and 
give off smoke, and are excellent and useful tools at hackerspaces.

How does a TIG welder have "the potential to produce red hot metal slag if 
you're using it to remove material"?  I've never heard of this.
Citation needed!

"Not everyone knows that welding galvanized metal or chromed metal gives 
off harmful fumes" but also not everyone knows that using the laser 
engraver on moleskine notebooks or any plastic with vinyl gives off DEADLY 
CHLORINE GAS yet we decided to take a huge risk and get a laser engraver 
anyway - and no one has died yet.

Have you noticed that we have propane torches?  We also have a drill 
press, chop saws with no safety buttons, a fucking table-saw (with no 
hotdog sensor), a laser engraver, and yes, dozens of soldering irons.

All of these tools have safety precautions.  Don't laser ABS plastic (like 
what comes out of some of our 3d printers) because it emits CYANIDE GAS 
and tends to melt.  cutting PVC emits chlorine gas!  yes, people should 
not use the TIG welder on galvanized metal, they might get the metal flu.

I think we can handle making a few warning signs, a ventilation system, 
and a vinyl curtain to block UV rays from escaping.  We are hackers and we 
are capable of operating dangerous equipment.

I think we should take Martin up on his offer and get some gloves, masks, 
and pliers.  I've got one welding mask and set of gloves on it already.
Then Martin will give a demonstration / instruction class and we can all 
see how excellent TIG welding can be.
