1- 	On-hands training IN installing ........
2-	On-hands training ON installing....

Answer

Use "in" before a field of study or expertise.  For example:
I have hands-on experience in carpentry.
My degree is in Biology.
I've been working in business management since 2004.

Answer

Hi Farhad!
I would say #1 using "in" however "for" would also be appropriate depending on the sentence :)

Answer

Thank you Peter
