John,
Did you have the machine set to AC and high
freq continuous? I was having a really tough time one day until I figured out
that the machine was still on DC. It just won't work that way. Also, make sure
the tungsten isn't contaminated, and if there is black smoky looking stuff on
the weld, that's oxide. It melts at about 5K degreesF, so that will also cause
your part to melt. If you have the machine set right, and the proper size
tungsten, and enough gas (need more in drafty conditions) , aluminum is
easy to TIG. Sounds like a machine setup problem to me. Mike
