Recently came across a great deal on a brand new Miller 200 tig set up. Been practicing on some mild steel . Kinda takes some getting used to after using a mig for several years. My question is What are the starting points for aluminum? Reason I ask is a friend of mine has an aluminum boat that has a cracked weld where the eye is welded on the front of the boat (where the rope ties on). It just needs a small weld. Any idea where to start.....filler rod, heat setting ,tungsten diameter, etc? Also I did a search but did not come up with anything that helped. Thanks in advance.
