Hi,
I see that such problems are not typically discussed in the forum but I hope somebody can help me. As university researcher I work with an old (1991) Plasma Technik M500T plasma spraying system. Better to say I would work if it were working
The troubles began when the powder feeder did not started but the plasma was ready. Nevertheless I was able to spray with a simple gravitation feeder which I get from a simple combustion gun.
Since then an other problem has arisen: the automatic starting process stops at the third step and the plasma flame doesn't forms. (for appreciatives: X117 input is inactive.) This means that the current reaches only appr. 170A and the voltage is 80V instead of the operating 68V, Argon is flowing.
I would greatly appreciate any useful advice to solve the failure(s) before we would be forced to call a technician from Sulzer Metco for on-site repair. Thank you!
