Re: [sudo-discuss] welder in sudo room

Hi Hol, that's a really neat welder! If you want to tune it up and make it work better, you might want to replace the tube that the wire gets pushed through. When it develops friction, the drive wheel can't push the wire through reliably. Fortunately the tube can be replaced with bicycle brake cable! Just get some of the good stuff (teflon lined) from a bike shop, and razor off the rubber coating so it fits in place of the original hose. The welder will work better than new! As for the flux-core wire, it is very dangerous to use that indoors, because the flux is for preventing oxidation - and our lungs need to oxidize! So it should never be used indoors (and using it outdoors will require a shield so passersby don't see the arc) At some point we should talk about making a ventilated corner of sudoroom, where welding and other fume-producing tasks can take place. Hell, maybe the Robot will be welding by then. http://www.youtube.com/watch?v=osErRS4m4S8#t=55 -jake Hol wrote: i brought in a small wirefeed welder. it uses fluxcore wire so doesn't require a shield gas, just turn it on, clamp the ground to your work, point and click. the wheel that drives the wire from the box through the cable to the gun doesn't have very good traction, so check there if the wire doesn't feed. the welder uses 17 amps so only use directly plugged into an outlet (!!!) bring steel! the antique saw actually works really well for cutting stock down to size
