Welding Muntz Metal

I used to weld a lot of Muntz using Silicon Bronze filler rod. TIG welded it
using DCEP, using either pure or 2% thoriated tungsten, sharpened to a point.
The key to a good weld is to watch the weld puddle, and adding filler rod at the
correct time. If you wait a second too long, the puddle falls away. With a
little practice, you can make very nice welds that are imperceptible after
grinding.
