  • I hope they are not teaching you that flux core is a GMAW process. FCAW is Flux Cored Arc Welding, GMAW is Gas Metal Arc Welding (hard wire). ;-)

  • T-11 :) i was doing that today in college... my coveralls completely ignited and combusted on me from the heat coming off of that...

  • I miss old school SMAW!!! That's what built America! But the FCAW is more economical and just as strong as stick!

  • I love fcaw and hard word u don't have to Chang out the rod everytime MIG and fcaw r faster

  • I agree with mosses

  • We no longer need to use welding machines -all we have to do now is spray on some jet fuel and light a match, presto weld complete.

  • i hate the gmaw saying when you think about it all envolves some kind of shielding gas and metal the only onethat is suitably described is gtaw or tig because it is using tungston

  • did anyone notice or was it just me? That construction guy was doing some serious number crunching off the top of his head! WOW what a genius!

  • @Gobnobber i think this was t-9 wire being used. it has that purple flash to it. plus t-9 has seismic properties in the wire.

  • @msanchez007 be the 1/8th in and up plate cert. aws D1.1 or something i beleive. you do the test in dual sheild though, but it covers flux also. test is a double bevel V-groove 1 inch thick, overhead and vertical.
