Re: Arc Welding on engine muffler area?
You're better off following the advice above.
Trying to weld the low quality steel muffler to the low grade aluminum the jug is cast from is almost guaranteed not to work. An arc hot enough to weld the muffler material will create a puddle of liquid aluminum between your feet.
Any day that starts with a good ride is already a better day, and a bad day riding still beats a good day working.
