Just finger tight it on, there is no need to crank down on it with any amount of force. As soon as the switch in the head is depressed and the plasma cutter kicks on, it should be tight enough.

I often exchange the nozzle and electrode,so that thread has a little tolerance and must tight enough to plasma cutter kicks on.
if this will cause life of start cartridge(9-8213) bring down?

My start carridge that is working 7 hour in day only using for 30 days .reed

What is the life span of the start cartridge? with heavy cutting I would be expecting to replace that part at least 2 times in a month.

Typically for a light use table where you are cutting almost every day, the lifespan ends up being about 2 weeks per start cartridge, possibly a month with clean enough air.
