Quoted from Ballsofsteel:

i've become quite good at guiding my solder at the point of connection with my teeth at times. just cut off a 5 inch piece or so. i've had enough fumes in the oil and gas industry that a lil solder doesn't bother me, compared to welding indoors without vents, cleaning out water trucks tanks used to haul crude oil, breathing natural gas, working inside a treater building, etc. etc. etc
