Inside Housing Temp is too high. Resulting in plasma being shut off at the end of start up (torch axis, EM, Plasma correction, standard lenses tune, resolution/ axis, performance report). I a have to reignite plasma and it runs to completion without shutting. Not a daily issue but happens 3 out of 5 days of the week.
2. Sampling cone is not tightened enough.
3. Laboratory Temperature and Humidity condition.
