What neighbors? LOL
My garage is heated to about 50 degrees all winter, unless I am working in there then I will turn it up. So no need for the block heater, but I did have the doors open, and the air temp was 0F.
I have used a Lincoln welder before, when I put floor pans in my Corvair, and I had good success with it. At work I have a MIG welder, and that is nice to use, but for around the house I am sure I can mange just fine with this Lincoln welder.
