Blender:

What gage aluminum were you trying to weld? Lack of penetration seems to be typical with these little welders, but then they are designed to weld REALLY itty-bitty stuff.

I watched a video of a guy repairing a ring that had either been broken or sawn off. He filed a vee in the break almost to the bottom, then started filling the gap with repeated passes using an Orion to weld in a REALLY fine gold wire as a filler. He had steadier hands than mine ever would be.

I'm guessing that because the weld cycle is so short, and you can only get about 1 weld per second, that the heat doesn't have a chance to build up in the part?
