"When I got it home I made a steel table - no problem., but I couldnt weld anything aluminum without melting the entire piece." 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.
