Highly dangerous

Soldering tool was stored in a dry and dark in toolbox. After I had not used it about 1 year, I've refilled it. When inflamed, the entire unit was under fire. Between the black base and the transparent incipient shell plastic parts have become leaky. This most likely attributable to fatigue defect should not appear on this unit after 2 years.
A star because he has to work in the first year.
