6. Our advice

Every time you change nozzles, material batches or working conditions (site, workshop, summer or winter, etc.), check the heating temperature of your appliance.

Proceed as follows:

• bring the nozzle close to the material without contact (approx. 5 mm gap),

• Observe: the material must melt (shiny appearance) without deforming under the air flow (wave), without changing state (liquid), without strong odor, and without changing color (no degradation),

• check the quality of the material's deformation on contact,

• change the temperature setting downwards or upwards if necessary,

• change ventilation settings as a last resort, if necessary.
