How do I size aluminum welding rods? How do I size aluminum welding rods?

When you use aluminum welding rods, you need to remember that it is a hot weld that will go fast. As you become more experienced with aluminum welding rods, you will realize that the more welding you do on aluminum, the better the finished product looks. But you can still over-do it, if you are not careful. Always go with an aluminum welding rod that is much bigger than you will need. In order to do the job right, you need to see what you are doing. When you are learning, use 1/8 inch rods, to get a feel for how they weld. Once you gain experience, you can start bringing rod sizes down, to accommodate your jobs.
