Not a professional welder by any means. Self taught with a very old Harbor Freight 240v Mig welder but it finally failed on me the other day. Boss bought a new Titanium Mig170 from Harbor Freight yesterday and I am impressed! Welded this today on a very rusty Van Hool muffler. Probably going to need to do the other tail pipe soon but I didn’t have time today because the bus had to leave ASAP!
