I have never wired aluminum...until today. Having huge problems with an edge start (non submerged machine Mitsubishi 90C) The wire breaks instantly as soon as it contacts the work piece. Right now I'm about at wits end, I have been playing around with it pretty much all day and while I got one part started (after it started it cut fine), this next part seems like its even worse (same thing as the first, just another one), and I can't get the wire to stop breaking. I have tried all different flushing settings, and even machined a little piece of material with a slot in it and clamped it to the work to contain the fluid, cranked the wire speed all the way up, dropped the voltage change over (for different work piece thickness) as low as it goes (64 volts), power as low as it will go, tried coated wire, plain brass wire, (all .012) and nothing seems to make a difference. Material is Alcoa 6061, 1" plate (Made in USA) Got a good ground, nothing mechanical I see that would be breaking the wire.
Is there some special procedure you have to use for Aluminum? I have no epacks for Al. so in the dark. I'm kind of leaning towards it being something with the machine, if you hand jog the wire in .0001" increments, it cuts, but since I don't have any experience with Al. trying to find out if there could be something I'm missing to make sure I eliminate all the simple things it could be. Thank you so much for any input!
