How to ask for a raise as an associate.

I don’t plan on moving up in the company but i’ve learned a little bit of everything. How to put in window leads, how to cut wire, rope, carpet, wood, blinds, and louvers. I also have all my licenses at my store there’s only 5 machines. I make 22 and some cents with the most recent raise as of a couple days ago. I’m not too happy because it was only 3 percent. My first raise was basically the same when i had no licenses and no knowledge of the rest. I’ve been with the company for 1 and a half years and the basic pay you come in at my store is 21$. What are the chances of me actually getting a higher raise if i ask them?
