I'm sure everyone has seen those fume extraction and ventilation systems for sale for anywhere between $1500-$5000 and up. Ventilation is a must, but spending that kind of money seems ridiculous. This is a simple design I came up with using 8 inch duct work, a 735 CFM greenhouse fan, an outside vent fixture, and an adjustable mount that can hang on my shops rafter ties. I tested it out running a couple of 6011 rods at 125 amps and sure enough it sucked the smoke right out. Total cost: $200
Reply:my fume extractor...
Reply:I'd recommend some metal at the inlet for at least a couple feet to minimize the risk of sparks catching your flex duct on fire. It can also give you some solid to help position it if you make it moveable somehow. I see you also have a fire extinguisher there, so good on you! Looks like a good setup.-DaveXMT304 with: 22A Feeder, or HF251 Hi Freq DC TIG air cooled

Reply:Great ideas. I just ordered an optrel swiss air PAPR to wear because my setup isnt conducive to fume extraction like this. $1300 hit.www.FirehouseFabricators.comZachMillermatic 255Lincoln SW200Hypertherm Powermax 45xp2x4 CNC Plasma Table.

Reply:My welding shop outside in field . My machine shop was indoors. It is very common to see a welding/fab shop outside with small building for machine tools only In Fresno California. It cuts the overhead down.Dave PS If you wonder how you in rain 🌧 simple save work that can be done in the machine shop last or when rains 🌧.

Not everyone is going to set up camp in the driveway to do a welding project or weld multiple pieces for production work. You really need a hobby, dude. You reply to nearly every single post with a lot of times some very objectionable advice. Its getting old.
Reply:I used umbrellas 🌂 for rain 🌧 too.Not used in the summer The welding table was under a awning still outside. Dave

My actual land is 40x100 and my neighbor is about 10 feet away. The exhaust from the garage does a nice job building up iron on my truck that has to be regularly removed with expensive automotive iron remover. It's just not quite farm country.... I'm considering buying a building for my business to operate out of, but to the tune of 7 figures while I currently have no real overhead its a tough decision.

Reply:Did you buy one buy for the mice and bugs. For summer you setup air duck from the evaporate cooler. I use a small evaporate cooler when welding outdoors in 110° F days. It like sea breeze while welding. Note I pointed air on me not the weld.Dave

Reply:Maybe Keeping the overhead down and living where on good year we 10" of rain 🌧. But start work in high school and then college as a iron worker. FYI iron work paid for college no loan or GI loan. Wall of college paid for.Dave
