The rotary control on the REAR OF THE HOT-AIR TOOL ENABLES ACCURATE SETTING OF THE WELDING temperatures up to 700șC

Plastic components can be repaired from the front or the rear according to ease of access.  Reinforcement welds can be used across the rear of a front repair to restore strength to areas designed to withstand impact.

If the damage passes behind a decorative or protective trim this must be removed from the damaged component to provide complete access to the repair area.  Trims are usually fixed with an adhesive that softens with heat treatment.  Attempting to remove a cold trim can damage it beyond repair.
  Moving the hot air tool over the trim surface aids even heat absorption to soften the adhesive. It also prevents localized heat build-up causing damage. When the adhesive is soft the trim should pull away neatly, allowing re-use after the repair.

The LEISTER TRIAC hot air tool can supply 230 liters of air per minute at a precise temperature between 20 and 700°C.  For trim removal the hot air tool is used without a welding nozzle at a temperature of 300°C.  The temperature charts on the tool body show the rotary control setting to achieve the correct air temperature.  Whenever the hot air tool is in use the barrel becomes extremely hot. Do not touch the barrel and always rest the tool on its stand when not in use.                                                          
The rotary control on the rear of the hot air tool enables accurate setting of welding temperatures  up to 7OO°C
