Thanks for acknowledging the assistance. It just means I have to keep working for you now
If its the plasma cutter telling you its lost an arc and not a synthesised one from the torch voltage, then it really lost the arc. This could have happened becasue you were too high. .060 sounds better to me.
If you are experiencing intermittent/random faults it will be becasue there is not enough current flowing through the plasma cutter's relay which results in oxide build up on the contacts. There was a thread on this recently. The solution (which you should do anyway) is to add a pull down resistor from the mesa input to field power ground (0 volts). We recommend you add 3 x 27 ohm 5 W resistors in parallel. This will give 90 ohms at 15 W current handling (6.4 W dissapation required). This will see 267 mA flow through the relay to get well above the 100 Amp minimum we've seen on a couple of machines now (Everlast and Hypertherm). It may take a few cycles to settle down but it will make for a more reliable signal. You should not really be cutting without an ArcOK.
Other causes could be poor earth or cutting too fast.
Oh, and there should be an application in the menus to take a screenshot.
