    Default Welding Fume Extraction Holding Arm

    I had no idea how many health issues welding courses until I started looking into Fume Extraction. Particles damage the lungs. Most extraction systems don't filter the gas unless they have a charcoal filter which is an optional extra in most.
    Galvanized steel, Stainless steel and Aluminium are all bad for your health.

    Even though I have a well vented work space I am still installing a fume & particle extraction system. If your space has a low ceiling like mine than you require an extraction system that removes the fumes & particles from two different locations. The particles from the arc level and the fumes above your head. That way there is only clean air below your nose.

    Fumes are not just smoke but toxic gases including the shielding gas.

    I am currently testing the amount of suction power required to extract particles, but with any new product there is always welding. I started welding a holding arm for the suction nozzle. It will sit up in the portal frame of my bay when not in use.

    Holding arm installed tucked up into the ceiling area out of the way.
    Able to be rotated and extended to any position on the welding bench.
    Just have to fab the nozzle and it's attachment.
    I have also fixed my Tig hose to a portal frame so it also drops down from the ceiling. This gets it off the bench or floor away from red hot material. This also ends the constant fight with the heavy hose.

    Well im convinced i dont like you! you have all the cool ideas, an unlimited supply of aluminum that in itself is just not fair and you seem to be a **** of a welder.Yup convinced dont like ya Just kidding, very nice as usual seems like you have a great start. So where does all the bad stuff go once evacuated from work area?

    Hi Three Turbos,
    Because I don't have a charcoal filter in my shop vac, I will keep the shop vac outside the welding bay in open air. That way the bad stuff goes outside away from me to become even less parts per million. I also have to form a spark arrester for those wayward sparks that may get into the vac or lodge in the hose and melt or burn stuff.

    Nice intro mate ha ha ha.
    Pretty cool
    Keep well

    Ji,
    I agree that fume extraction is very important, but I also worry about abrasive dust among other things. I considered fabricating a system like you are building, but it seemed like a daunting task. Here is the solution I came up with. Let me know what you think.

    Hi Kiwi,
    Yes those units are regarded as the best system for multipurpose use.
    The other unit you should consider is the down draft table.
    That is where the vac sucks all the fumes and grindings down under the table. They where designed for grinding on as well as welding on.
    There as some great you tube vids that you can take a peak at.
