The plain-words read of this example
40.0 ft of 0.2500 in fillet weld holds 4.68 lb of steel weld metal (0.117 lb/ft). At 95% deposition efficiency for GMAW you buy 4.93 lb of filler, 5.17 lb with 5% extra: 1 × 33 lb. At 6.0 lb per arc hour and a 35% operating factor that is 0.78 h of arc time and 2.23 h of welder time. About 1 pass; job total $185.37, $4.63 per ft. Minimum preheat at 0.500 in: None above 32°F (0°C) base metal.
