The La Tecno ST1 Heat Shrink Gun features forced air to evenly apply heat across the surface of the capsule. Hot air is pushed downwards over the shrink capsule and results in more uniform shrinking, faster process, and consistent results. Traditional heat shrink guns with hot coils, but no internal fan for forced air, can cause the capsule to wrinkle as it shrinks. Chrome-plated body with insulated handle and three-position switch for off, cooling, and use. 1,000 Watt / 110V.
