LOL. Its funny Darren, we have a gasless unit on site and we drag it out from time to time when its a simple pain to get gas bottles upstairs into the plant where there is no lift. We have a pool of boilermakers from Dawsons and to be honest, they could probably weld using chopsticks they are that good. I have seen welds laid by guys up there on SS316/SAF2507 and 904L, acid affected as well, that are absolute works of art, verticals, overheads, just head shaking unbelievable. My little 24/36V Rediwelder runs flux core and it lays a good bead, but dragging the batteries out of the truck to do it, nope, not happening.
