are the fumes from FCAW more dangerous than other, or is just quantity that matters the most in this case ???

some people says that FCAW procedure is more dangerous because it produces much more cancerogenic particles than other procedures...
is that true, or is just bull...???

thank you for your answer in such a short notice :) i am an IWE, and i don't want to use cellulosic electrodes in my technologies anymore...especially when it comes to high risk pipeline systems with gases and other dangerous and flamebale fluids...in Serbia, these electrodes are very common and all...

7016 are electrodes with both types of polarity...why they are so neglected when it comes to root passes ???

it would be a nice thing if somebody take a video of that procedure...

thanks in advance...
