I wouldnt think just the outside motor would require an a/c license. U mite try to find a motor elsewhere with the same power supply requirements and output arbor diameter.
Off the subject though, but did did end up gettin a plasma cutter and tig machine?
I am ordering a new MIG and a spool gun for aluminum next week that is cheap for what I am getting. I would like a plasma but I should hold off until I have a real need for it. I figure I can make some stuff and sell it to earn the money for a better MIG and a nice plasma intead of getting a cheap plasma. I will practice aluminum and then make some boxes to put up for sale. A MIG and a decent cut off tool should be all I need to make some nice boxes. Plus I like to weld so it will be fun. I may try my hand at making a dog/hog trailer for myself too. If it is good enough maybe someone will buy it. I would love to make enough to quit the job I hate so much.
