    Default Welding ventilation

    I have been burning a bunch of 7018 and a little 6011 trying to practice. I have had lots of ventilation for the fumes. The thing is that the weather is starting to cool off and I wanted to know how much ventilation that I need to have. I'd like to go inside and close the shop door a bit to stay a little warmer. I will say that the cold encourages me to weld almost constantly! My little inverter welder doesn't mind because I stay at the 100% duty cycle amperage or below.

    Depends on the size of the shop and how airtight it is, but if you can smell it, it's WAAAAAAY too much. Put a fart fan in the side of the shop near your work area, and create a closeable (or self-closing) fresh-air inlet near a heater so the incoming air won't be freezing.

    Install a exhaust fan in the wall or a box fan by a window. Position a fan to suck fumes and smoke away from you. COLD ? What's your temperature out there ?

    The lows this week in Flagstaff are running between 3 and 8 degrees above. You have to call ahead to RV parks so they can plow a space for you.
    Flag averages just over a hundred inches of snow per year, much more at higher elevations. There's a ski resort just outside of town and another ski run about 30 miles away in Williams. I've worked many, many times in sub zero weather across No AZ. Like he said, AZ has a wide variety of terrain.

    Where are you at? We should get together and drink some beer and talk about how cool blue stuff is... ha! Flagstaff is essentially where I'm at.

    I know this sounds a little stupid but when sticking, I take a deep breath and have learned how to hold it in and release it slowly, the odd time I need another, I just get another one in and do the same again but I never let the fumes get near my helmet and for sure never inside it.

    I'm based out of NW AZ but I work all over.

    I get a kick out of some people, I was in Wyoming and the guy next to me in the RV park was from Minnesota, he told me "it doesn't get very cold here, this is WAY south of where I live".
    He lernt a harsh lesson, 25 below with a 40 mph breeze will freeze up a "weekend camping trip" type RV in about 2 1/2 minutes. But it was the guys first job on the road so he was pretty shallow into the learning curve.

    I've worked in El Paso Tx in single digits, and cars were sliding off wholesale on the ice. That's pretty far south too : )

    Some folks are happily unaware of conditions beyond their backyard, outside of what they see in the movies ; )
