I'm having a little trouble with my O-attys, and thought to ask the assembled experts for help
I've been using SS316L, 26 ga. Single, compressed coil, around .4 ohms. Often, when I first fire it to make sure everything is good, one of the legs - the one wrapped around the positive post - breaks. The end of the wire is clipped to the inside, and isn't touching anything. This happens perhaps 50% of the time. What am I doing wrong?
TIA!
Sounds like a severe case of hot legs. Make sure the outer coil is making good contact with the inner coils on both sides and especially the hot side. Short pulses with a squeeze of the ceramic tweezers while firing should do the trick.
