Prachya Isarow in action in Hua Hin.
Both players struggled in windy conditions at the Hua Hin Centennial Club in the ATP Challenger Tour event.
The first set was close but SEA Games champion Warit ran out of ideas in the second.
In the second round, Prachya will meet Japanese Yuichi Sugita who beat India's third seed Yuki Bhambri in the first round.
The Indian retired due to an elbow injury after losing the first set 6-0.
"I made a lot of unforced errors but he did not play well,'' Prachya said after the match.
"It will be tough against the Japanese although I have never played against him before because he qualified for the main draw at Wimbledon in the past two years."
