My cousin bought one, pretty sure its the same model a few years ago. I used it to build this for him:
You will NEVER go back to a grinder with a cutoff blade, or a torch. You will get spoiled instantly. Cuts 1/2" like butter.
Tip- for straight lines, get a piece of high temp plastic about 2" wide, 1/2" tall, and about 2-3 feet long. Comes in Very handy, you rest the tip on the plastic, and just slide the gun along. The 1/2 tall plastic holds the tip exactly 1/8" off the metal. It has to be plastic so that the tip doesnt arc. A local welding shop guy told me that, and sure enough, worked perfect.
