Buying a welder, which kind? which model? which brand? and beginning the process of developing the design for the roof on our structures

After researching all the various types of welding it is apparent that each style has their own highs and lows.  It seems that stick welding it hot, deep, and produces a lot of spatter and a mess to clean up.  MIG welding, especially using flux core style wire feed, appears to be a great way to control and get started with very little experience.  While TIG welding appears to be one of the best, but requires more experience and skill to create beautiful and amazing welds.  While I may not be spot on for what I just said, this is what I have learned and I am here to share my own experience.  The welder that we are focused on buying is the EASTWOOD ELITE MP200I MULTI PROCESS WELDER - MIG, TIG, STICK.  This device does all 3 types of welding and has a current price of $799.99, but after JUST CHECKING right now... the sale is showing $699.97!!!  OMG, I bought the welder (05/08/2020) even though it is out of stock until 05/17/2020.  But I don't need it today, but having it would be a real motivator to get into the yard and start getting my lessons going forward.

I called Eastwood and asked about the details related to this device.  Since the electrician is going to be coming by soon and installing the electricity into the garage, we will want to install the right 230V VAC socket to accommodate this device.  They confirmed that the socket will be the following type:
