The 5000BTU (~0.4 ton) window unit I have installed makes a noticeable difference in the comfort level of my garage. On a hot day (90-95F/95-100%RH outside), temp in garage will get over 80F (when I set the unmarked thermostat so that the compressor will cycle on and off) but the humidity is knocked down to about 50%. 50% is still a little higher than I would like but MUCH better than 100%. I have some box and radial fans on standby but haven't done enough hard work out there to spin them up so far.
If you're going to be welding, you'll need to keep a close eye on your A/C filter(s).
I'm hoping that when I finish insulating the ceiling the A/C will be able to drop the humidity even more. I also need to install a seal on the bottom of the garage door - bought the seal, just haven't felt like installing it.
Edit: An extractor hood would probably be counterproductive - it would blow your conditioned air outside and suck outside air inside.
