The incident occurred in January almost three years ago in Sävsjö.
The violence caused both pain and second-degree burns.
According to the verdict, the motive is partly divided.
The burnt man claims that it was a discussion that was behind it, while the now convicted man says that he was upset about how the other man behaved towards him.
Serious assault
The man is sentenced by Eksjö District Court to two years in prison for aggravated assault, unlawful threats and minor drug offenses.
He has admitted certain parts of the course of events, but denies the crime.
