The fan will draw away the fumes and pull in air from behind you. Just make sure it is close but not too close to hinder your flame. The flex duct is easily suspended by hangers or even rope.

I wouldn't use this as ventilation for fuming. The torch plume, complete with exhaust gasses and metal vapors, will spread quickly as it rises and creates turbulence in the air around it. A furnace booster fan won't give you enough pull to capture this exhaust plume. You really need to use a hood of some sort as described by Carolyn.
