Mike Hull said:I think the biggest difference besides power is the AC/DC abilities of the more expensive units.
Rob! said:The etchomatic also has AC/DC capability - just uses a small diode on the ground clip. It works great and in this case, the low power is almost an advantage because it goes slow enough that you don't go too far too fast or burn out your stencil.

I'll try it again with many more shorter bursts and less solution. Also I'm using the general purpose solution for A2. Is there a better solution??
