Hi Dan, I also just bought a Hobart Tigwave 250 in February of this year. I am just like you and spent alot of time looking for information on my welder, most of all i was looking for the manual for my welder. If you do a search on this site you will find a posting i made for the different shops that have the manuals for our welders, i listed some other shops that can do repairs on the P.C.boards used in our welders.
You will find that the people on this forum are very kind and helpful and they take the time to answer all of your questions. As you spend time here make sure you check out the items that are listed for sale, i picked up a nice pulser for my Tigwave 250 from a member in Canada for only & 50.00 dollars, and let me tell you it sure makes welding thin sheet metal super easy.
If you would like to add a pulser to your welder contact me i know of someone that may have one for sale just let my know and i will put you in contact with him.
