the past few days, i have been contracting to an industrial construction company. they are making a cooler for an aggregate drier "cooler". the finished product was coming out of the cooler still way too hot and needed more surface area. the drum is 36 foot long (only the last 15 feet get the fins) set on 4 inch centers... my big blue pro 300 is getting a decent lil work out as the fins are welded solid weld on both sides to the drum. im still in the fit up phase, so more pics to follow... (btw, the fella in the last pic (part of the construction crew is 6 ft 4 and 300 pounds)..... to give you an idea of the size of this "giant radiator")

i have a trailblazer 302 and 12vs suitcase, im using that to tack it all together and for fit up, i have a stand alone feeder on a frame with wheels powered by the pro 300 that i will be running 1/16th FCAW. the fillet on the weld was spec'd to 5/16... i can do that in a decent paced single pass with the bigger fcaw wire....this one is definitely a one time deal, i doubt very seriously that i will EVER weld 3/8 rings on a drum on 4 inch centers.....................ever...

this might be the wrong thread to post this, it should go in the "not so bright" thread, but, it was on this job..... get this.... I'm running 1/16 fcaw with a c02 shield (not a self shielded wire) and the engineer comes over and decides that i shouldn't be using flux core because the breeze was puffing a little bit and that i should be using solid wire mig.... when i told him that both use an inert gas shield over the weld puddle, he abruptly and snidely replied " Well, I am the engineer..." and to which i replied "y'all are paying me by the hour, i'll run 3/32 7018 stick rods if that's what ya want" (they are on a time constraint and need this thing welded out by Tuesday morning) so, its on to 16 hour days until its welded out with .035 solid wire mig...... baaaaaaaahhhaaahhahhhahahahahaaaaaa

they asked for a bid on this and i told them that there was absolutely no way that i or pretty much any other welding/ fab service that would bid it. i said hourly or not at all.... the construction company has used me a bunch in the past, i guess they like my smarta$$edness and my welds

here's another one from the same engineer that should be on the not so bright thread........ so, i'm welding with solid wire mig 12vs extreme and a pro 300 machine, and the engineer stops me and says that im running too hot... said that i have the machine set at 29 volts and that is too hot for .035 solid wire mig... i tried to tell him that the voltage at the feeder was gonna be less for having 150 foot of lead and 3 tweco style quick connects in line and get this: he says that i should not be having voltage and amperage drop through welding leads, that welding leads wont drop amperage over 500 foot let alone 150 foot.... where do they find these people???
i do like to run a little on the hot side as the rings are 3/8 and the drum itself is 1 inch thick... 200 amps @ 24-25 volts at the feeder and c-25 mix.... sounds like procedure not too hot
